Impact or Non-impact Screwdriver Which is Better

Top 14 screwdrivers

In general, a screwdriver is a device almost as versatile as a screwdriver or a hammer. Not a single repair or construction can be done without it. A good device can effortlessly cope with tasks such as installing audio or television equipment, installing baseboards or drywall, assembling furniture, attaching shelves and pictures, installing door handles and much more. The presence of a screwdriver, at the same time, makes the process not only faster, but also of better quality. A correctly selected model will help you cope with the task in a few minutes. How to choose the optimal solution? View my list of the best screwdrivers for the home.

Comparison

We have already found out that these power tools perform completely different tasks. But the main differences don't end there:

The rotation speed of a cartridge with a screwdriver is much lower, plus there is no inertial moment. In other words, as soon as you turn off the screwdriver (release your finger from the button), the chuck immediately stops, whereas when drilling it spins for some time by inertia.
Safety precautions. When working with a drill, experts recommend wearing safety glasses to prevent small particles formed during the drilling process from getting into your eyes. The screwdriver does not need to adhere to special safety precautions, you just need to be careful and careful when working with the fastener.
Various operating modes. It was stated above that the drill can be turned on in both normal and impact modes. The screw gun is regulated only by the rotation speed, nothing more.

The best corded drill driver

Battery-powered drills and screwdrivers are convenient and compact, but their corded counterparts cope better with heavy loads. In particular, among the popular models the following modifications should be noted.

The best impact screwdrivers in this class are Makita, Bosch, DeWalt, Metabo, etc. These devices are designed for serial installation of fasteners. They can also be used as a drill.

Among the equipment presented in this class, the Makita 6960 and the domestically produced device (together with China) Titan PUS 101 stand out.

Bosch Metabo Which screwdriver should I choose? GSR 12V-15 vs PowerMaxx BS

A Russian corded screwdriver intended for use in professional activities consumes 300 W during operation. The designers have developed an ergonomic body design and a comfortable handle. Thanks to this, high working comfort is achieved. Illumination of the working area is provided. Another advantage of the design is access to the carbon brushes without having to disassemble the tool. Titan PUS 101 is a worthy competitor to similar foreign models of professional equipment.

The Makita 6960 impact drill/driver is characterized by high torque. Her weight is optimally balanced. The handle has a built-in reverse switch. This is a worthy tool that will be easy and fast to work with.

Among the types of network equipment, one most popular model stands out. The Makita TD 0101 impact screwdriver is considered one of the best for home use. This device has a tangential impact. It is directed across the axis of rotation. When tightening screws or other fasteners, it turns out to increase the torque. Thanks to this device, the presented screwdriver greatly facilitates the work of the master.

One of the advantages of the model is the smooth speed control. At the same time, working with the presented equipment is noted as comfortable. You can perform all the necessary actions all day long without getting tired.

Among the disadvantages of the model, users note that the cord is not long enough to connect to the network. If desired, you can replace it or use an extension cord. Users also claim that there may be a slight lack of power when drilling into hard materials. This complicates the process. However, the lightness of the device and its thoughtful functionality make the presented model popular among users. For home use, the presented model has enough power, quality and comfort.

Screwdrivers from the best manufacturers

Specifications

Looking at the impact screwdrivers on sale today. You should familiarize yourself with the basic technical characteristics of household and professional models.

The power of network devices for home use ranges from 200 to 500 W. The same figure for professional equipment is over 500 W. If the master purchases a battery device for household purposes. A device with an operating voltage of 9.6 to 14.4 V is suitable. This figure for a screwdriver that works frequently and for a long time is from 14.4 to 18 V.

The battery capacity of a household appliance is 2 Ah, and that of a professional one is 4 Ah. Conventional screwdrivers usually do not have the ability to change speed. Professional equipment has a wider range of functions. Therefore, in such devices there are 2-3 speeds. Their torque is 20 Nm or even more. Household screwdrivers have this indicator at 15 Nm.

In addition, specialists purchase a tool that is not afraid of loads, mechanical shocks and even falls from a height. The cost of such devices is quite high. Therefore, more fragile but cheaper power tools are used for home use.

Impact screwdriver and its advantages

Large torque, in some models reaching 250 Nm.
Convenience when tightening screws and screws. With a low level of resistance, the tool is able to operate in shockless mode, developing the continuous force required for tightening. If the resistance increases, the tool switches to impact mode, when tightening is performed with a high torque.
There is no need for large pressing forces, which allows you to save the surface of the screw heads from “licking”. This feature of the tool makes it possible to unscrew screws whose heads have already begun to lift up.
The amount of torsional load on the user's wrist is reduced.

General characteristics of the tool

Impact screwdrivers are designed to perform a number of functions that were beyond the capabilities of the usual variety of such equipment. This power tool is designed to screw in and unscrew screws, drill holes of various diameters, tighten, etc. It significantly speeds up the work process, improving the quality of the final result.

There is a wide selection of models of such equipment on sale. First of all, there is a distinction between professional and household screwdrivers. Their characteristics meet the requirements of different categories of masters.

There is also a corded and cordless impact driver. Each of them has its own advantages and disadvantages. The specifics of the wizard’s work allow you to select the optimal type of device.

Today, the power tool market offers customers a large selection of domestic and foreign devices. Depending on the technical characteristics, the price of the presented equipment is determined. When choosing an impact screwdriver, you need to have knowledge of the advantages and disadvantages of each model. This will allow you to make the right choice.

Chuck type

The function of fastening various drills in the tool, as well as attachments, is performed by the chuck.

Key. It is widely used due to its low cost and reliable fixation of the drill. A special key is used to tighten or loosen. The disadvantage of such a cartridge is that you can lose the key.

Quick-clamping. It is easy to use, has proven itself in everyday use, can be clamped by hand and provides reliable fixation. However, it has a higher cost compared to a key chuck, and with a high torque, fixing such a chuck may not be enough. Available in the following versions:

single-socket – to replace the drill, the spindle must be fixed. Depending on the drill model, it can be locked automatically after stopping the engine, as well as using a locking ring or a locking button;
double-clutch - clamped with two hands.

MK 2, MK 3 – with Morse taper. Used for heavy drills and bits and provides the necessary fixation as well as centering.

Weldon 19 mm - used in heavy drilling units for heavy attachments, cutters and drills of large diameters.

G 1/2”, 1 1/4” UNC – a specialized chuck for fastening diamond bits when working on concrete.

7/16 Hex – chuck for hex shank. Used in screwdrivers.

For installation in chucks: MK 2, MK 3, G 1/2”, 1 1/4” UNC, Weldon 19 mm, 7/16 Hex conventional drills, a corresponding adapter is required.

What to look for when choosing?

If you want to purchase an impact screwdriver (corded or cordless), you need to pay attention to the factors that determine your choice. First of all, experts recommend identifying the scope of application of this equipment. If the master uses the device once or twice a year, you can give preference to simple models. Their cost will be less than that of more powerful equipment.

However, even for a one-time use of an impact driver, it is worth considering the future load. For example, when assembling a garage or other metal structure, you should not purchase the simplest, low-power devices. In this case, the work will take more time and effort. Also, experts do not advise purchasing the cheapest power tools from unknown manufacturers. Such equipment quickly breaks down.

If a master uses a tool in his professional activities, it is better to give preference to a more durable, powerful screwdriver. It will allow you to solve even complex repair problems. The cost of this equipment will be higher than that of simple models. But a screwdriver quickly pays for itself when carrying out repairs or other work at a professional level.

The work of a home craftsman or professional builder requires the use of special tools. It must be universal, allowing several actions to be performed using the same equipment when carrying out repairs. Among the electrical tools, one of the most popular is the screwdriver. It may have various additional qualities. These include the possibility of impact during operation of the mechanism. This expands the scope of the tool.

Users also note such a model as Ryobi R18PD-LL15S. The set includes 2 batteries. Thoughtful ergonomics allow you to work for a long time without hand fatigue. There are 2 speeds, which increases the range of capabilities of the presented device.

What criteria should you pay attention to when choosing a screwdriver?

If you are wondering which cordless screwdriver to choose for your home, then you should pay attention to the main characteristics and additional functions, because they may be useful in one or another job.

Design

The battery device may have the following design:

Pistol . Standard perpendicular position of the handle in relation to the body. Pistol-type devices are comfortable to hold and apply pressure during drilling/unscrewing. If you don't often have to work in cramped conditions, then a pistol screwdriver is your option. We also note that units of this type, with other indicators, are more powerful than corner “Shuras”.
Corner. In these models, the cartridge is located at an angle, thanks to which you can get into hard-to-reach places, for example, when you need to screw in screws somewhere under the ceiling. Also, corner devices are very convenient when assembling furniture. However, if you are engaged in serial assembly of furniture, then most likely a pistol device will be enough for you.

Function difference

Most screwdrivers on the power tool market today belong to the semi-professional class. This means that the equipment has improved qualities, but does not meet the requirements for professional devices.

Almost all manufacturers produce both powerful and simple models. The most popular impact driver is Makita. Bosch, Metabo, and among domestic brands - Interskol, Zubr.

A professional tool is distinguished by its ability to work without interruptions for a long time, high power, and quick replacement of equipment. This type of device does not require too careful handling and is distinguished by its endurance and durability.

Home screwdrivers are characterized by a more modest set of qualities. It should be said that in professional series of equipment there are also low-power types of products. For example, this is a Bosch Professional impact screwdriver with a 10.8 V battery. However, they are included in this group due to their high build quality, thoughtful ergonomics, and long working life. Such devices are indispensable, for example, in furniture assembly plants.

Disadvantages common to impact screwdrivers

Despite their fairly extensive list of advantages, impact screwdrivers are not without their disadvantages, the main ones of which include:

Low twisting speed in case of transition to impact mode.
Impossibility of using jaw chucks, except in rare cases. Impact tools are almost always equipped with hexagons.
Inability to install a torque limiting coupling. For this reason, control of the entire process rests with the worker, which can be quite inconvenient, since the tool shaft rotates at a very high speed.
Increased noise level when using shock mode.

How to choose?

When choosing a specific impact screwdriver model, pay attention to the smallest details. The first thing people usually pay attention to is the type of food. Pneumatic models are definitely not needed at home, but electric ones can be mains or battery-powered, as mentioned above.

The network option is good for working in an equipped room; it is most valued for its almost unlimited power. Having given preference to such a device, evaluate its cable - it should have a significant length and thickness, have good insulation and not raise doubts about the strength of the place where it enters the unit.

In the case of the battery model, there are more selection criteria. First of all, you need to find a balance between the large capacity of the battery, which extends the battery life, and the weight of the device, because a capacious battery always weighs quite a lot.

Another point is the choice of battery type: today the most common are lithium-ion models, but nickel-cadmium models are also found. The first ones are good because they have a small mass with a significant capacity, they allow charging at any time, but they are more expensive than their main competitor and can quickly wear out at low temperatures. The advantages of the nickel-cadmium solution completely offset the disadvantages of the lithium-ion version - such a battery is cheaper and is not afraid of frost, but it is both heavy and environmentally hazardous, and most importantly, it must be completely discharged and then fully charged, otherwise the “memory effect” will cause rapid wear of the media.

Which screwdriver to choose: impact or simple.

At high voltage, the engine power also increases, but for home use you don’t need sky-high performance: 500-700 W is enough, otherwise the tool will turn out to be heavy and unreasonably expensive.

The screwdriver chucks in which the replaceable attachments are mounted can be quick-clamping or key-type. The first can be organized in different ways, but its advantage is that maintenance can be done with bare hands. The key cartridge has a characteristic rim; servicing it requires a special key, which is not always convenient.

Since we are talking about the cartridge, an important criterion is the maximum diameter of its opening - the larger it is, the more different attachments you can use.

Maximum torque is an indicator of how hard the attachment will rotate. This indicator does not always directly depend on the power of the motor; sometimes it can be increased due to the gearbox, but it is always desirable that the maximum torque be quite high. Models with continuously adjustable torque are preferred, since they are more gentle on fasteners and surfaces being drilled.

Differences between impact and non-impact drills

Impact and non-impact drills differ primarily in the type of application:

a) material processing . As already mentioned, an impact drill is used on wood and metal, but a regular drill is used on wood, plywood and plastic. However, with more powerful characteristics, ordinary drills are sometimes used, both on brick and concrete.

b) impact mechanism . This mechanism (back and forth movement) is present only in impact drills, rather than in conventional ones. As a result, the hammerless drill is light in weight.

In second place are the differences in the characteristics of these two instruments:

1. Power . Typically, impact drills, due to their back-and-forth motion feature, have higher power compared to a regular drill.

The power range in a conventional drill is from 300 – 600 W.

The power range in an impact drill is from 500 – 1200 W.

2. Rotation speed . The torque in impact drills is faster than that of conventional drills.

3. Weight and dimensions . A regular drill is lighter than an impact drill.

4. Type of cartridge. This characteristic varies among the drills under consideration. Conventional drills mainly use a keyless chuck, while impact drills use a serrated or key chuck.

A chuck is a device necessary for fixing drills and other types of drill bits. There are different types of cartridges:

The quick-clamp is intended for heavy loads and hard materials, for beginners when working with a drill.
A hexagon bit is used for various types of drills.
Gear or key - a chuck with a jaw clamp for professional work.

Final differences between impact and non-impact drills:

1. Price . The cost of an impact drill is higher than the cost of a non-impact drill, since the functionality of the first is much richer than the functionality of the second.

2. Quality . The same can be said about quality. Analyzing the main differences, we can conclude that since a conventional drill is lighter than an impact drill, it means that it is usually made worse, which explains its short period of operation.

What is it and what is it for?

An impact screwdriver is a special power tool that allows you to most effectively drill into walls for the purpose of screwing in screws and installing other fasteners. Unlike non-impact models, this relative novelty on the domestic market makes a hole not only due to the actual rotation, but also with the help of directed impacts. The latter usually do not have a permanent nature - the corresponding mode is turned on at the operator’s request or automatically if the drill encounters an obstacle of particular hardness. In a sense, it's a little jackhammer.

An impact screwdriver is a device in itself that is more complex and “smart,” so a certain versatility should not be surprising. This means that the tool, as a rule, is fully compatible with various attachments, due to which the scope of its potential application expands significantly - instead of a drill, you can attach, for example, a hole saw or a mixing attachment.

Do you need an impact driver?

It is logical that such a tool costs slightly more than non-impact models, but its purchase is often justified even at home - the external, load-bearing walls of multi-story buildings are usually distinguished by their highest strength, which only an impact screwdriver can overcome.

The device is also appreciated by professionals who drill walls or various parts every day - according to them, with all its assertiveness, an impact screwdriver drill usually does not cause significant damage to fastener elements, increasing their durability. This characteristic is especially valuable in the context that the same tool is often used to assemble furniture.

The classification of impact screwdrivers is not so extensive, but is still capable of driving many inexperienced consumers into a dead end. What is most confusing is the logic in dividing tools into drills, screwdrivers and screwdrivers, but in reality everything here is extremely simple: the mechanism is generally the same for all, and the exact name depends on the attachment.

Thus, a drill is usually equipped with a drill for making holes, and a screwdriver and screwdriver are also able to screw in fasteners. Some models require simple replacement of attachments, so they may have complex compound names like “screwdriver-drill,” but if such multifunctionality is not provided, the unit is called the most exact term.

Often, when choosing, beginners are also confused by the fact that the device is supposedly electric and pneumatic. Electric models are the most common, especially at home, but pneumatic ones are perhaps very rare models that will definitely not be in demand at home; their main places of use are various service stations and tire shops.

Since the screwdriver runs on electricity, it should be noted that it can be both mains-powered and battery-powered. The first is good for minor home repairs or daily work in a well-equipped workshop, because it is lighter and the technician does not need to constantly remember to charge the battery.

However, it is the battery version that is the only solution during the construction process or for outdoor use, when the work site does not require the presence of functioning outlets.

Which Screwdriver Is Better Impact Or Non-Impact

One of the typical criteria for assessing the masculinity of a house owner is considered to be his ability to drive a nail (or, in modern terms, screw a self-tapping screw) into a wall. Without this simple skill, it is impossible to hang a shelf, decorate a room with a painting, or install a curtain rod.

An electronic screwdriver is designed to cope with this task more quickly and without unnecessary effort, and an impact screwdriver is often praised, but, alas, not many people understand what it is and what it is for.

An impact screwdriver is a special power tool that allows you to drill into walls better with the intention of screwing in self-tapping screws and installing other fasteners. In contrast to non-impact models, this relative novelty on the Russian market makes a hole not so much through actual rotation, but using directed impacts. The latter usually do not have a constant character - the corresponding mode is activated according to the operator’s wishes or automatically if the drill encounters an obstacle of particular hardness. In a sense, it's a small jackhammer.

An impact screwdriver is a device in itself that is more complex and “smart,” so a certain versatility should not be surprising. This means that the tool is fully compatible with different attachments, which is why the scope of its potential implementation expands significantly - instead of a drill, of course, attach, for example, a hole saw or a mixing attachment.

It is necessary to distinguish between an impact screwdriver and the same drill. The latter, being aimed at making holes, implies a longitudinal direction of blows, while a screwdriver hammers in some way longitudinally, thereby significantly increasing the torque.

Content

Is it worth overpaying for a blow in cordless drills and screwdrivers?

It is reasonable that such a tool costs slightly more than non-impact models, but its purchase is often determined even at home - the external, load-bearing walls of high-rise buildings are usually distinguished by high strength, which only an impact screwdriver can overcome.

The device is properly evaluated by specialists who drill walls or various parts once a day - according to them, with all their persistence, the drill of an impact screwdriver usually does not cause significant damage to fastener elements, increasing their durability. This feature is especially valuable in the context that the same tool is often used to assemble furniture.

The systematization of impact screwdrivers is not so extensive, but in any case it can drive many inexperienced consumers into a dead end. The most confusing logic is in dividing tools into drills, screwdrivers and screwdrivers, alas, here we will try to consider this issue in detail: the mechanism is ultimately similar for all, and the clear name depends on the attachment.

Thus, a drill is usually equipped with a drill for making holes, and a screwdriver and screwdriver can also screw in fasteners. Some models imply a simple change of attachments, therefore they have complex compound names like “screwdriver-drill”; on the contrary, such multifunctionality is not provided; the unit is called a more precise term.

Often, newcomers in the selection process are also confused by the fact that the device is supposedly electronic and pneumatic. Electronic models are more common, especially at home, but pneumatic ones are just very rare models that will definitely not be needed on their own; the main places for their use are various tire shops and workshops.

Since the screwdriver runs on electricity, it is impossible not to clarify that it can be both mains-powered and battery-powered. The first one is not bad for small home repairs or everyday work in a well-equipped workshop, because it is lighter, and the master does not have to constantly keep in mind that the battery needs to be charged.

But specifically, the battery version is a non-alternative solution during construction, or in other words, for implementation simply on the street, when the work site does not imply the presence of functioning sockets.

When deciding whether to choose an impact or non-impact screwdriver model, you should first understand how they differ.

Some consumers who have managed to evaluate the performance of the impact mechanism will say that such a unit is better, and this is how they are ready to prove their point of view.

Through targeted impacts, the torque of the impact tool is increased to a range of 80-250 N/m, making it possible to break through more complex obstacles. It is significant that throughout it is not even necessary to press the body tightly against the wall - the tool bites into it even without significant pressure.
In the absence of the need for constant physical effort applied to the tool, the wrist and hand of the master get tired much less, which increases the same productivity.
Taking into account that even a strong wall is not able to successfully withstand the pressure of such a tool, it usually does not deform the fastener, which will allow it to be removed in the future without additional effort. In addition, some models provide an additional reverse function for removing old fasteners from the walls, even those that have experienced severe deformation due to long-term use.
The screwdriver works not only with bolts, but also with nuts, each time achieving a very tight tightening. A “smart” machine usually automatically switches from shockless mode to shock mode when it senses that the nut has become tighter at a certain moment.

Unfortunately, such a solution will have certain shortcomings that will never allow it to completely supplant non-impact models. Thus, an impressive twisting speed is observed exclusively in the unstressed mode; when switching to impacts, it decreases significantly .

Not just any chucks are suitable for such a tool - strictly hexagonal ones are required. Most models do not have a limit coupling, so the degree of tightening must be carefully monitored by the operator, otherwise there will be no damage to the wall or other parts. After all, at high speeds such a unit is capable of producing loud construction noise, so constant work with a child implies the indispensable use of protective equipment.

When choosing a specific impact driver model, look at the smallest details. The first thing people usually look at is the type of food. Pneumatic models are definitely not useful at home, but electronic ones are mains and battery-powered, as described earlier.

The network option is not bad for performing work in an equipped room ; it is more appreciated for its virtually unlimited power. Having given preference to this particular device, evaluate its cable - it must have a significant length and thickness, have good insulation and not even cause fluctuations in the strength of the place where it enters the unit.

If the passage with a battery model, the selection criteria is not easy. First you need to find a balance between a large battery capacity, which extends battery life, and the weight of the device, because a large battery always weighs a lot.

Another point is the choice of battery type: now lithium-ion models are more common, alas, nickel-cadmium models are also found. The first ones are quite good because they have a small mass with a significant capacity; they allow you to always charge, but they are more expensive than their main rival and there are variations that quickly wear out at low temperatures. The advantages of the nickel-cadmium solution completely offset the disadvantages of the lithium-ion version - such a battery is cheaper and is not even afraid of frost, but it is both heavy and environmentally unsafe, and - it must be completely discharged and then fully charged, otherwise the “memory effect” will provoke rapid wear of the carrier .

Batteries can produce different voltages, but for repetitive household work, choose models with a value in the range of 12-18 V.

At the highest voltage, the motor power also increases, unfortunately, for use at home, sky-high characteristics are not necessary: 500-700 W is enough, otherwise the tool will turn out to be languid and unreasonably expensive.

The screwdriver chucks, where the replaceable attachments are attached, can be quick-clamping or main. The first one may be organized in different ways, but the gaming slots have it in such a way that the service is performed with bare hands. The main cartridge has a corresponding rim; servicing it requires a special key, which is rarely convenient.

Since we are talking about the cartridge, a fundamental aspect is the largest diameter of its opening - what makes it more difficult is that they simply use different nozzles.

The maximum torque is an indicator of how hard the nozzle will rotate. It is rare that the indicator directly depends on the power of the motor, and it may be increased due to the use of a gearbox, but it is always better that the maximum torque is sufficiently high. Priority is given to models with continuously adjustable torque , since they are most gentle on fasteners and surfaces that are drilled.

The last, but very important aspect of choosing a tool is its weight. Unfortunately, it is impossible to make a lightweight, yet powerful and functional device, so you need to decide what is more important: lightness or performance. Please note that with constant everyday work, the first factor is much more important.

The use of an impact screwdriver will be harmless and very effective only in such a situation if done correctly. Of course, the first piece of advice is to read the instructions before implementation; alas, there will be other reasonable tips for use.

For example, if possible, do not set the equipment to the highest torque, because some fragile materials with a treated surface for this reason can simply be torn, and you will ruin the workpiece. In addition, working at maximum speeds up the wear of the tool, we are not saying that in this mode it needs to be held more tightly, otherwise there is even a possibility of injury.

Review of screwdriver vs impact driver, Makita DF030 vs Makita TD090

The operating modes, when, are described in the annotation not by chance - they imply rational options for performing this particular task, but may not be suitable for another. Thus, drilling is needed to make holes, and the screwdriver mode is needed to screw in fasteners; using the opposite reduces efficiency, but increases the risk of injury.

It is completely unacceptable to change options on the go, with the chuck rotating - this can break the unit.

Always wear safety glasses and gloves, especially when working with fragile materials. When drilling into walls, make sure in advance that there are no electronic wires there. Remember that the continuous operation time of the device is limited - if the nozzle or other unit becomes noticeably hot, let them cool down.

When, if a drilling mode is not provided in a certain screwdriver model, then it is better not to even try to drill anything while using it - such experiments often end with a burned-out engine.

When using a cordless screwdriver in cold weather, be aware that any type of battery, and especially lithium-ion, will discharge much faster, so you need to charge it more often.

If you received a battery-powered model, remember that the battery should always be in the disconnected position, except for specific work. With all this, the nickel-cadmium battery must be completely discharged before turning off the device, and then immediately put on charge . Besides everything else, it is also not capable of storing a charge for a long time even at normal conditions, so it needs to be charged from time to time, even if you haven’t used it.

Operating rules

The use of an impact screwdriver will be safe and most effective only if it is done correctly. Obviously the first tip is to read the instructions before use, but there are other sensible tips for use.

The operating modes, by the way, are described in the instructions for a reason - each of them assumes optimal settings for performing this particular task, but may not be suitable for another. So, drilling is needed to make holes, and the screwdriver mode is needed to screw in fasteners; when used, on the contrary, efficiency decreases, but the risk of injury increases.

Always wear safety glasses and gloves, especially when working with fragile materials. When drilling into walls, make sure there are no electrical wires there in advance. Remember that the continuous operation time of the device is limited - if the nozzle or any other component gets noticeably hot, let it cool down.

By the way, if a particular model of screwdriver does not provide a drilling mode, then it is better not to try to drill anything with its help - such experiments often end with a burnt out motor.

Drill power type

Network. The most common drill models by power type. They can operate both from the mains and from diesel or gasoline generators. Easy to maintain, they have higher power, longer operating time, and performance compared to battery-powered ones.

Rechargeable . They are a portable tool; I can work in various places where there is no electrical network or where it is impossible to use an extension cord (carrying). Can be used as a screwdriver.

Mobile drills require constant maintenance of batteries, which quickly discharge and heat up during intensive use, so it is recommended to have a spare battery included.

For stationary work

Powered drills are recommended if there is no particular need for mobility. Why buy a cordless drill when your home is full of outlets?

For work away from the network

Cordless models are more powerful than cordless screwdrivers, so they are in demand among specialists working “in the fields” - outside the coverage areas of electrical networks.

One of the unique criteria for assessing the masculinity of the owner of the house is considered to be his ability to drive a nail (or, in modern terms, screw a screw) into the wall. Without this basic skill, you won’t be able to hang a shelf, decorate a room with a painting, or install a curtain rod.

An electric screwdriver is designed to cope with this task faster and without extra effort, and an impact screwdriver is especially often praised, but not everyone understands what it is and why.

Difference between drill and screwdriver

On the modern market of power tools you can find a wide variety of options that greatly facilitate construction, finishing and other types of work. When it comes to comparing a screwdriver and a drill, many people simply do not see the difference in these devices. Of course, they can be understood: in appearance, both power tools are very similar, even more so. They can perform the same function. For example, many craftsmen use a screwdriver as a drill. That is, using a special drill, they make a hole (the main purpose of the drill). However, there is a difference between the two devices in question, and it is significant. In this article we will focus primarily on the differences between them.

Distinctive features

When deciding whether to choose an impact or non-impact screwdriver model, you should first understand how they differ.

Many consumers who have had time to evaluate the performance of the impact mechanism will say that this particular unit is better, and this is how they are ready to justify their point of view.

Due to targeted impacts, the torque of the impact tool increases to a range of 80-250 N/m, making it possible to break through the most difficult obstacles. It is significant that during the process there is not even a need to press the body tightly against the wall - the tool bites into it even without significant pressure.
Without the need for constant physical effort applied to the tool, the master's wrist and hand get tired much less, which allows for increased productivity.
Considering that even a strong wall is not able to successfully withstand the pressure of such a tool, it usually does not deform the fastener, which will allow it to be removed in the future without additional effort. Moreover, many models also provide a reverse function for removing old fasteners from the walls, even those that have experienced severe deformation due to long-term use.
The screwdriver works not only with bolts, but also with nuts, in each case achieving the tightest possible tightening. A “smart” machine usually automatically switches from shockless mode to shock mode when it senses that the nut has become tighter at a certain moment.

Unfortunately, this solution also has certain disadvantages, which may never allow it to completely displace shockless models. Thus, an impressive twisting speed is observed only in the non-impact mode; when switching to impacts, it decreases significantly.

Not just any chucks are suitable for such a tool - you need strictly hexagonal ones. Most models do not have a limit coupling, so the degree of tightening must be carefully monitored by the operator, otherwise there will be damage to the wall or parts. Finally, at high speeds such a unit is capable of producing deafening construction noise, so constant work with it requires the mandatory use of protective equipment.

Advantages and disadvantages of percussion type instruments

For many buyers who are faced with the choice of which drill or impact driver to choose, the question arises as to how an impact driver is superior to a non-impact model.

The increased torque allows the technician to apply significantly less effort when working with the tool, without putting pressure on the body itself. For most models, the values of this indicator range from 80 to 250 N/m.
Can be used not only for self-tapping screws, but also for working with nuts. When the product moves freely, the screwdriver operates in standard mode; when resistance occurs and the free movement of the nut along the thread decreases, the mode automatically switches to impact mode.
Since there is no need to make excessive efforts to tighten the bolts and screws, the caps are not deformed. The power of the tool is also sufficient for the reverse action - unscrewing components that have modified their original shape or have rusted;
The ease of use of the tool also helps relieve stress from the user's hand and wrist.

The limitations and disadvantages of impact-producing screwdrivers include a decrease in the twisting speed during the impact mode, since the actions of the tool are concentrated on the turning moment and the quality of work. You can also only use hex chucks. The degree of twisting must be controlled independently, since there is no limit coupling. There is also an increased noise level when working at intensive speeds.

Care Tips

If you purchased a battery-powered model, remember that the battery should always be in the disconnected position except during direct operation. In this case, the nickel-cadmium battery must be completely discharged before turning off the device, and then immediately put on charge. Among other things, it is also not capable of storing a charge for a long time even when idle, so sometimes it needs to be recharged, even if you have not used it.

Comparison in numbers

So that you can compare similar models of impact and non-impact screwdrivers yourself, let’s summarize their characteristics in a general table:

So, now you have all the information you need to understand how interesting a tool such as an impact driver is for you.

I put all my soul and all my knowledge into the materials I write in the hope that it will be useful to visitors to our site. I would be very grateful to everyone who decides to write their opinion about my work, their comments and suggestions in the comment form available after each of my published articles.

Features of the shockless design

It is known that the simpler the design, the more reliable it is. Due to the absence of constant alternating loads, the chucks and rotors of impactless screwdrivers are less susceptible to wear. Add to this the relatively low cost, small size and weight, longer operating time without recharging - and we get a number of obvious advantages over impact tools. So, if the main task of the device is to work with wood and soft brick, screwing and unscrewing serviceable fasteners under light loads, then preference should be given to a non-impact screwdriver.

Problems will appear when the owner of the tool has to face complex tasks. The main disadvantage of a hammerless tool is its almost complete uselessness in drilling hard, inelastic surfaces, such as concrete or stone. When working with damaged or rigidly mounted fasteners, there is a high risk of damage - the working head will just scroll in the cross or on the hexagon without doing any useful work.

Main types of device

What types of screwdrivers are there:

Household. Used for small household jobs.
Professional. Suitable for specialized daily use. They are more powerful, equipped with additional functions, cost more, and are designed for long-term use.

The device is divided into types, differing in their function:

electric impact wrenches;
cordless screwdrivers;
drills and screwdrivers.

Electric impact wrenches

Used for installation and dismantling of threaded connections. In addition to the rotational movement, an impulse with a certain frequency is transmitted to the working part, which allows you to unscrew even rusty connections. Mostly they have a “pistol” shape, rarely they can be “straight”.

Distinctive features:

low rotation speed;
high torque;
lack of torque regulator;
the presence of a square adapter for socket heads;
good as a separate addition to a screwdriver.

Electric impact wrenches

Cordless screwdrivers

They are inferior in functionality, but have certain advantages:

light weight;
compactness;
have a lock that allows manual tightening;
possibility of using the device in cramped conditions;
equipped with a chuck adapter for hex bits.

Screwdrivers differ in layout; they can be pistol-shaped, folding, with a swivel joint on the working head. The device's battery is not removable and is charged from the mains.

The disadvantages include:

small battery up to 9 V;
low rotation speed up to 250 rpm.

Cordless screwdriver

Drills and screwdrivers

The most widely used type of instrument. One device combines several functions: drilling, driving, turning out screws.

Distinctive features and features:

presence of an air cooling system;
the body is equipped with rubberized pads;
simple speed switching;
different types of cartridges;
torque control;
works for a long time without recharging;
lightweight battery.

In order to understand how to choose a drill/driver, you need to study the parameters, decide what needs the device is for, and choose the type of battery.

Drill/driver

Which is better: an impact or non-impact screwdriver?

Their advantages and disadvantages will help you determine whether an impact or non-impact screwdriver is better.

Pros and cons of the impact device:

copes well with concrete and brick, although it lags behind the hammer drill;
no tool can compare with it in screwing “with interference”;
easily unscrews damaged fasteners;
there is no strong impact on the human wrist;
rapid wear of the impact mechanism;
high noise level;
work speed decreases;
no additional components.

Important! The cost of a percussion instrument is an order of magnitude higher than that of a non-percussion instrument.

Pros and cons of an impactless device:

simple design;
low cost;
small weight and dimensions;
works longer without recharging;
copes well with wood and soft brick;
useless when drilling hard materials (concrete, stone).

How then to choose a screwdriver if both options have disadvantages? In this case, a powerful impact device is ideal for professional use. You should choose one with a capacious battery and a high rotation speed. This screwdriver will not let you down under heavy and frequent loads.

For home use, a hammerless tool is sufficient. They can be found from Russian and Chinese manufacturers.

Impact or non-impact screwdriver: what to choose and in what case

The main feature that distinguishes a screwdriver from a drill is its compactness and the ability to operate autonomously. Just a few years ago, the operating time of the device without recharging was relatively short, but today, after the advent of more capacious and energy-efficient batteries, manufacturers were able to significantly increase the mobility of screwdrivers and provide them with new functions. One of them is the impact mechanism. Which is better - an impact or non-impact screwdriver, and what criteria should you use to choose this tool?

Rating of popular models

Which one is better to choose? To purchase the best impact screwdriver model, experts recommend that inexperienced users consider a number of popular devices offered by well-known manufacturers. In this case, it is worth studying in advance the main technical characteristics, pros and cons of both battery devices and network devices.

Pros and cons of an impact driver

If you have tried to drill concrete with a regular screwdriver, then you probably know how long, labor-intensive and thankless it is. An impact screwdriver can easily cope with such a task and gives an advantage when working with brick and masonry, but still its efficiency is far from the capabilities of a full-size impact drill and, especially, a hammer drill. But in tightening screws and screws “with interference,” the impact screwdriver has no equal.

In addition, the tool makes it relatively easy to unscrew fasteners with a damaged cross or partially erased edges. Do not forget that during long-term continuous use, an impact tool does not load the wrist as much as a non-impact tool.

However, the impact design can create a number of inconveniences:

The pusher mechanism is subject to rapid wear, which is especially pronounced in inexpensive models.
With the transition to impact mode, the operating speed drops significantly, and the noise level, on the contrary, increases.
An impact driver cannot be equipped with such useful components as a jaw chuck (hexagons are almost always used) and a torque limiting clutch.

How a corded and cordless impact driver works

An electric impact screwdriver, whether corded or battery-powered, provides a tangential impact in a plane perpendicular to the axis of rotation. In other words, when tightening screws, the force generated by the tool is not continuous, but is a high-frequency series of small blows. Its operation is similar to what happens, for example, when putting an open-end wrench on a nut and tapping the wrench with a hammer.

The total force that a corded or cordless screwdriver of this type develops is the sum of the forces of the blows it produces during a unit of time.

Externally, the impact screwdriver is very similar to its non-impact counterpart:

Regular non-impact screwdriver

What to choose and in what case?

For professional work, the best choice would be powerful impact screwdrivers from Bosch, Makita, Einhell, DWT and other well-known brands. They will not let you down in construction and repair, and will help cope with damaged or outdated threaded connections. Give preference to better models with a high spindle speed and a capacious battery.

At the same time, for home use you should pay attention to cheaper models. The same companies offer entry-level non-impact tools; in addition, good impact and non-impact screwdrivers can be found from domestic manufacturers and Chinese brands, for example, Zenit, Vityaz, Intertool, Sigma.

Ultimately, the only thing you need to know for sure before choosing any tool is where, for what and under what conditions it will be used. Based on this, it is easy to choose a model that will fully satisfy all your requirements.

Design

According to the principle of power supply, power tools can be battery-powered or mains-powered, operating at a voltage of 220 V. Despite these differences, the tools are similar in appearance and internal structure. They consist of the following parts:

Plastic or metal case.
Clamping chuck for various attachments.
On/off buttons
A reverse switch that allows you to adjust the screwing in and unscrewing of fasteners.
Speed controller that controls engine speed.
Power-on locks.
Tightening force adjustment switch.

Inside the housing there is an electric motor with a board and capacitor, a coupling and a gearbox.

Drill/driver

This is a universal tool. They can be drilled and screwed on without fear of ruining the piece or excessively submerging the cap into the material.

There is a configured mechanism (popularly called a ratchet) through which rotation passes. Once it reaches a certain resistance that you set, it simply snaps back in one click and the bit stays in place, secure and reliable.

In addition, a drill-screwdriver differs from a regular electric drill in that it is equipped with a gearbox, which has a large gear ratio. Therefore, with the same motor power, the drill/driver has a higher torque value. This means that, for example, a power cord drill with a 400 W motor will have the same torque as a 700-800 W drill. However, the sizes will be smaller.

The price paid for it. Fewer maximum spindle speeds. If it reaches a value of 3000 rpm per drill, then their number per drill is no more than 600-800. And if it is a two-speed one, then all the same, the revolutions do not exceed 1500 per minute.

Thus, we conclude that the drill bit is a good all-round option as it can handle most of both drilling and self-drilling jobs.

However, such a tool will not replace a drill for work that requires high rotation of the chuck. This is, for example, drilling bricks, when the work takes place in shock mode. And although some models of screwdrivers have a hammer mechanism, it is not very effective due to the low speed.

It should also be remembered that they not only drill with drills, but also, for example, mix mortars using a mixing attachment. And here, too, high speed is needed. Therefore, the driver is also poorly suited for such work.

Special mention should be made about cordless drills. Firstly, these are drill-drivers that are made with a battery, but there are no classic drills with a rotation speed of up to 3000 rpm with a battery.

Secondly, using battery technology has both advantages and disadvantages.

The advantages include the following:

Independence of work. That is, the ability to work for a certain time away from power grids with pre-charged batteries;
There are no wires, which is convenient, for example, when working on the roof.

The disadvantages are the following:

Aging batteries. If used frequently, they tend to last no more than 3 years, and if they are rarely used, they still age and become unusable anyway after 5-8 years, even if they are just sitting idle;
Inability to immediately start working if it suddenly turns out that the batteries are running low.

These are my thoughts on this matter. I hope that after reading the article, you will understand for yourself which tool you need. Let me finish this. Until we meet again!

Screwdriver

The screwdriver can only be used to tighten the screws as it only has a hexagonal seat for the pieces. Although it should be said that there are also drills with a hexagonal lining, how to beat, but they usually only come in a small diameter, and they are not on sale everywhere.

Thus, for this tool we conclude that it can only be purchased for tightening screws. At the same time, remember that it is tied to the network, which means that you will not be able to work with it autonomously.

It is more convenient to use this device in any assembly workshop where work is carried out at one workplace to tighten self-tapping screws or self-tapping screws.
