Which household hammer drill is better to choose for work: rating of popular models, user reviews (Top 8)

Types of rotary hammers

First of all, when choosing a tool - not just a hammer drill - it is worth answering two questions: how often will you use the tool and what do you need it for.

If you want to do home renovations and don’t plan to frequently drill holes in the walls in the future, then there is no point in spending money on expensive professional equipment. Otherwise, professional craftsmen can safely pass by shelves with “household” devices, since they are not intended for daily and complex work.

Like other repair tools, hammer drills can be divided into three types:

• Household . A distinctive feature is its low weight, within five kilograms. Used for home repairs and simple work. Often, for the sake of savings, manufacturers refuse additional functions and complex settings.
• Semi-professional . A borderline option that is suitable for both amateurs, not limited by budget, and professionals. Such hammer drills are more powerful and, accordingly, heavier than household models.
• Professional . The most serious cars are powerful and heavy. A professional hammer drill can weigh more than 9 kg. Often has increased impact power. They can withstand high intensity of work and do not require frequent breaks in drilling.

Which brand of hammer drill should I choose?

Today, in any consumer electronics store you can find a couple of hammer drills from mass brands. However, we advise you to go to a special store for a special tool. There is more choice - and prices are often lower.

But how can a beginner understand the abundance of manufacturers and models presented? It is clear that you will have to pay extra for proven brands, and market newcomers often cost less. The price difference between the two classes of devices can reach 30-35%. But is such a discount worth the risk?

For example, hammer drills from the legendary Hitachi, Makita and Bosch cost 3-5 thousand rubles more than tools from little-known companies. Brands ask for money not only for the name, but also for the quality of the instrument for which they became famous. In addition, iconic companies often concentrate only on the production of power tools, and therefore rely on quality and technical know-how. This applies not only to professional models that embody the best engineering solutions, but also to simpler, household tools.

Of course, new companies try to attract new fans with a low price, an interesting set of supplies, or an additional guarantee. Therefore, you need to think carefully about what is more important to you - a couple of additional drills or, for example, an ergonomic design.

In any case, when choosing a hammer drill for professional work, we advise you not to save money and take a closer look at well-known brands that provide a guarantee of at least 36 months. If you need a hammer drill for your home, you can also evaluate inexpensive models from Chinese manufacturers, since the pace of home repairs depends on you. If the hammer drill breaks down on site, the timing of all work may be at risk, but at home you can calmly hammer the walls at a rhythm convenient for you.

Don't forget to carefully review the instrument's data sheet. This way you will find out all the technical characteristics of your future hammer drill and will be able to compare the models that interest you in all respects.

What to look for when choosing a hammer drill?

A hammer drill is a serious tool for punching holes in any material. Therefore, first of all, you should pay attention to the impact force of the model that you like. It will determine what materials you can work with, how long the process itself will last and how comfortable it will be. A tool with low (up to 2 J) or medium (4 to 10 J) impact force is suitable for home use. For professionals, it is better to take a closer look at hammer drills with a stronger impact (from 10 J).

What does impact force depend on? First of all, it depends on the power of the tool. The lowest power ones - up to 800 W - are suitable for home repairs. Medium-power (from 1000 to 1300 W) and high-power hammer drills (from 1300 W) are aimed at the professional market.

The next characteristic is the versatility of the tool. Rotary hammers can not only gouge holes, but also drill them. Therefore, if you need a multi-functional tool, you should avoid choosing rotary hammers with one operating mode. Some professional tools can also drill.

Another important parameter for any master is the ergonomics and weight of the device. Naturally, the heavier the instrument, the more powerful it is. Therefore, professional hammer drills can weigh from 7 to 12 kg. You won’t be able to hold such a tool in your hands for a long time, which will naturally affect the pace of work. There are two options: go to the rocking chair or choose an easier hammer drill. The optimal weight for home is 3-5 kg.

Last but not least, the factor is the type of food. It is logical that there are wired and wireless devices. The first ones are perfect for home repairs, since the outlet is most often at hand. Cordless hammer drills are useful in a de-energized facility where there is no electrical wiring yet.

A special case is pneumatic hammer drills. They operate from high-pressure pneumatic systems, which are usually located in workshops. If you do not plan to work in a factory, then simply avoid the shelves with this tool; you are unlikely to need such hammer drills in everyday life.

The best cordless hammer drills

DeWalt DCH481N-XJ

Another professional cordless hammer drill, whose characteristics are very similar to the previous model. Equipped with a 3,000 mAh battery. It has three operating modes: drilling, drilling and chiselling. Chambered for SDS Max cartridge. The advantages include the force of the impact mechanism of 6.1 J with a small weight of 5.4 kg for such power. Users note the high ergonomics of the device: the handle is equipped with a start button, which comfortably fits several fingers of the palm. For additional convenience, the manufacturer added a removable handle for drilling to the package.

True, specifically for this model, the manufacturer did not put anything else in the box. Additional batteries and charging for the hammer drill must be purchased separately. Because of this, the price of the device seems too high - from 38 thousand rubles in Russia. If such amounts do not scare you, then the tool is perfect for construction and finishing teams, installation of windows, entrance doors and even satellite dishes.

Bosch GBH 180-LI

The company that invented the rotary hammer (Bosch made the first rotary hammer in 1932) continues to produce high-quality tools to this day. GBH 180-Li differs from other models of the brand by its battery capacity of 4,000 mAh. In this case, the weight of the assembled device (including the battery) does not exceed 7 kg. A little heavy for home repairs, but perfect for professionals. They will also enjoy three operating modes: chiselling, drilling and hammer drilling. In addition, the model can tighten screws, which is convenient if you don’t have the appropriate tool at hand.

The GBH 180-Li is chambered for SDS Plus, so if you have drills with a standard connector from other kits, they can be used with this device. Another bonus is the extra battery included. By charging both batteries at once, you can work continuously for up to 1.5 hours. Minuses? First of all, the price. Bosch is asking up to 10 thousand rubles for a model on the Russian market. For this money you can buy several rotary hammers from our rating.

The best rotary hammers in terms of quality and reliability

If you need a good hammer drill that can delight you with excellent build quality and reliability, then you don’t have to choose a model from the professional segment. Well-known manufacturers today offer good options for tools in the middle power class (800 - 1200 W), even in the middle price segment, and their capabilities are enough for the average buyer even with a margin. In this category, we have also selected 3 of the most attractive devices from well-known brands that will be an excellent option for purchase.

KRÜGER KBH-1400

The Kruger hammer drill from the German brand has an increased power of 1400 W, so it copes well with a wide range of jobs such as drilling holes, breaking concrete, and dismantling various building materials. The Kruger rotary hammer is equipped with various functions, such as reverse. That is, if the drill gets stuck, the operator can easily pull it out.

The ergonomic rubberized handle provides a secure grip on the drill and prevents your hands from slipping. Light weight – 3.1 kg – guarantees ease of use of the device. You can work with a Kruger hammer drill for a long time.

Another advantage of the Kruger hammer drill is the rich equipment of the device. It comes with a high-quality depth gauge for drilling straight holes of the same length, an additional chuck that can be replaced with one click. Also included are three drills, a drill and a pick. The device fits into a convenient compact case for easy transportation and storage.

• light weight;
• comfort of use;
• three operating modes.

Flaws:

• not found.

AEG KH 27 E

One of the best rotary hammers in terms of operating reliability can undoubtedly be called the KH 27 E model from the world famous brand AEG. The power of the device is 825 W, which provides 1500 rpm at idle and 4500 bpm. The force of the latter is 3 J, which can be called an excellent indicator for a device of this class. Reviews of the KH 27 E hammer drill often highlight its low weight and good delivery set as its advantages. The maximum permissible drilling diameter when using this model is 13, 26 and 30 millimeters for metal, concrete and wood, respectively.

Advantages:

Makita HR2470

Makita rotary hammers are considered one of the best on the market today. The quality of the products of this Japanese company surpasses most of its competitors, although the cost of power tools from the famous manufacturer is at a very affordable level. The HR2470 model, equipped with a 780 W motor, was no exception. The capabilities of this solution from Makita are very impressive: three operating modes, drilling diameter up to 24 millimeters (for concrete), frequency and impact force of 4500 per minute and 2.4 J, respectively. The HR2470 is a high-quality and versatile hammer drill with good equipment and a 4-meter cable, which allows you to work with it over a large area. At the same time, the weight of the device is only 2.6 kg, which means the load on your hands when using it will be low.

Advantages:

• network cable length;
• high build quality and reliability;
• fits comfortably in the hand;
• protection against drill jamming;
• good protection against dust.

Flaws:

• not detected.

When choosing a manufacturer of rotary hammers, remember that even though models from different companies have the same functionality, a tool from a more well-known brand can cost an order of magnitude more. The main parameters that you should pay attention to when choosing a tool are power, impact energy, ease of use and reliability. For a tool used in everyday life, it is recommended to choose a hammer drill that has at least three operating modes. And, as a rule, it is worth paying attention to the presence of a protective coupling and adjustment of the shaft rotation speed.

The best networked hammer drills

Patriot RH 400

Semi-professional hammer drill for repair work. A fairly powerful model with an impact force of 9 J weighs only 6.3 kg, thanks to the magnesium gearbox. There are only two functions - drilling and chiseling, but if you have other tools in the house, the RH 400 can handle any task quite well.

A distinctive feature is the vibration damping system. Because of this, you can work with a heavy tool longer, without your hands getting tired from constant shaking. In addition, the handle is covered with a rubberized coating, which prevents your hands from slipping.

The manufacturer included a carrying case, a drill and a pair of chisels with a flat and sharp tip in the box with the device. Perhaps this will smooth out one of the few disadvantages of the device - the short (1.9 m) wire. For comfortable work, you will definitely have to buy an extension cord.

Price: ₽ 14,090

Makita HR2470X15

A convenient hammer drill for home repairs from a well-known brand. One of the obvious advantages is the long, 4-meter power cord. With such a length, you can safely work in small rooms, including under the ceiling. If the wire is not long enough, you can always use an extension cord. In addition, the manufacturer assures that the elements of the case and the inside of the device are protected from dust.

Makita engineers have seriously worked on the ergonomics of the device. Users note the good build quality and pleasant weight (only 3 kg!) in their hands. The handle does not slip in the hand even with gloves thanks to the rubber coating. The mode switch is conveniently located under the left hand. However, this option is not suitable for left-handers - the start button is on the right.

The package includes a special case for transportation with compartments for fasteners, drills and drills. For 8 thousand rubles - an excellent offer. Especially if you are not going to regularly tap walls or perform complex work on de-energized objects.

The best semi-professional hammer drills

A semi-professional tool can be used both at home and to solve some professional tasks in the field of repair or construction. A characteristic feature of such rotary hammers is the increased power of the power unit.

Bosch GBH 240 Professional

Abundance of modes, German quality
The GBH 240 rotary hammer is a real all-rounder. Such a tool will be appreciated by private owners engaged in repair and installation work. Impact force 2.7 J.

Find out the price

Reasons to buy:

• Reliability;
• Rich set of modes and functions;
• Improved design for increased performance;
• High quality cord 4 m long.

A powerful 4-mode hammer drill copes equally well with chiselling, impact and non-impact drilling. Reverse will help unblock jammed equipment, and thanks to it, the unit can be used as a screwdriver.

Bosch GBH has atypically high performance for semi-professional equipment - solely due to the innovative design of the gearbox. Smooth adjustment of the rotation speed is also available here - it ensures high-quality and accurate drilling in any materials. The only thing that’s a little disappointing is the traditional configuration for Bosch instruments.

Bort BHD-800N 1000-TURBO

A powerful tool for household use.
A surprisingly high-quality model with good power that can cope with serious, but short-term work on concrete. Impact force 3.5 J.

Find out the price

Reasons to buy:

• Good power;
• High-quality assembly;
• 3 operating modes (drilling, impact and drilling with impact);
• Very rich equipment.

A model with a good impact power rating will allow you to solve most everyday problems related to working on concrete and stone. The hammer drill is easy to use and built to last, which is not typical for budget “Chinese” manufacturers.

Among the pleasant functions there are: spindle locking, rotation speed adjustment. The tool itself does not overheat and can easily withstand increased loads, although it is not designed for professional use.

Many will be pleased with the extensive equipment: a case, 3 drills, a chisel and a lance, a key for the gearbox and replacement brushes. There is even lubricant, although initially the hammer drill does not require this - the gearbox is very generously lubricated.

The best hammer drills with two operating modes

Rotary hammer Makita HR2300

Inexpensive (up to 8 thousand rubles) semi-professional device for working at heights. Light weight and ergonomics allow you to operate the device even when climbing to the very top of a stepladder.

The engineers thought about left-handed people and created a convenient system for controlling the drill's reverse motion. Now the reverse can be started and adjusted with one hand, and with the other hand you can hold the device itself by the handle.

The delivery set, in addition to the case without additional drills, includes an additional handle with a locking button. In addition, you can adjust the rotation speed of the drill to accurately drill holes in ceramics or other difficult surfaces. Due to its versatility and low price, the model is perfect for home use.

Price: ₽ 8,560

Interskol P-32/1000E

Domestic hammer drill with a vertically mounted motor. This simplifies the design and allows all components to be contained in a smaller housing. As a result, Interskol managed to make a semi-professional device weighing less than 6 kg.

Russian engineers also used an anti-vibration system and an additional handle to adjust the drilling depth. Thus, the tool has become even more convenient when performing work that requires accuracy and precision. Adjusting the rotation speed of the drill also serves these purposes.

The delivery set already includes the usual case, but the manufacturer was greedy and did not include additional drills in the kit. In addition, many may not like the 2 unfortunate meter long cord.

Price: RUB 7,850

The best professional hammer drills for the job

Bison ZPV-32-1250 EVK

Inexpensive for a professional device (7-8 thousand rubles) model of domestic production. Supports three operating modes: can drill, chisel and drill. Thanks to a special damping mechanism, the device copes with vibration, which is especially noticeable when working with hard stone materials.

With a weight of 6 kg, ZPV-32-1250 has a small impact force of 3.5 J, which may not be enough for construction work. This is compensated by the motor power of 1250 W.

The delivery set is not rich: a carrying case, a depth gauge and lubricant. No additional drills, no second handle. The latter is not critical, because it can be purchased separately.

Price: RUB 7,510

Enkor PE-780/24ER SDS+

Lightweight professional model - only 3 kg. This is with an impact force of 3 J and a power of 750 W. Relatively low power narrows the field for the use of PE-780. Basically, a hammer drill is used as an additional tool for working at heights.

Additional advantages: a universal cartridge for the SDS Plus standard, three operating modes and a low price of 3.5 thousand rubles. The package includes nothing interesting: a carrying case, a depth gauge and an additional handle.

Price: RUB 3,367

The best hammer drills for home and professional use

To choose the right tool, you need to initially understand how you will use it. Light class models will not withstand operation on a construction site, but heavy class models will be able to demonstrate almost a third of their abilities in everyday life and will turn out to be completely useless if you need to carefully drill something.

Therefore, manufacturers conditionally divide rotary hammers into household and professional. The first ones are light class, with a horizontal or vertical configuration. Household hammer drills are designed for occasional use and can be used for drilling, hammer drilling and slotting. Of course, you can try to dismantle the wall with a household tool. But with a 90% probability, you will have to throw away the tool much earlier than the wall is dismantled.

Household hammer drills are offered by brands:

• Bosch - with green body;
• Hyundai;
• Skil;
• Hammer;
• Makita.

Many offers can be found from Russian brands:

• Caliber;
• Diold;
• Interskol;
• Energomash.

Professional hammer drills are designed for regular and long-term use. They endure an eight-hour workday and handle reinforced concrete work. They can work for a long time without interruption, without overheating, and without the risk of breakdown. It is easier and more comfortable for a technician to work with such a device: the impact force is greater than in light models, and the protection against vibration is higher.

Among professional models, the undisputed leaders remain:

• Bosch;
• Makita;
• DeWALT;
• Metabo.

The cost of professional models is several times higher than household ones. The difference in price by 3–4 times is explained by the design features of the devices.

The best home hammer drills

Soyuz PES-25101

Another inexpensive model that will cost no more than 5 thousand rubles. PES-25101 can drill, drill and chisel holes with standard nozzles, since the device’s chuck is made to the SDS Plus standard.

The model weighs a little more than its competitor in the “Best Home Hammers” category – 4.9 kg. However, the device from Soyuz carries a powerful (1000 W) electric motor that can withstand even intensive drilling for a long time. Working with difficult surfaces is a little easier due to the impact force of 4 J, which is more than enough for home repairs.

At a low price, the manufacturer supplies a rich set of bonuses with the device. There is a carrying case, two drills, augers, and a depth gauge. The kit also includes an additional handle for a second hand, for maximum fixation of the device during operation. Minuses? Perhaps only a two-meter wire, which is not enough to work in apartments with high ceilings.

Price: ₽ 4,760

Bort BHD-800N-K

One of the cheapest models in our top - from 3 thousand rubles. The BDH-800N-K is also very lightweight, especially compared to professional devices. Weighing 2.85 kg, the device can operate in three modes: chiselling, drilling and hammer drilling.

With such dimensions, an impact force of 3 J does not seem insignificant. This power is more than enough for home repairs. When working with concrete or brick, you should be careful, as the drill can get stuck in the material. However, the motor rotates the drill in both directions and the stuck tool can be easily removed.

Along with the hammer drill, the manufacturer included a plastic case, a second handle and a drilling depth limiter in the box. In addition, the case already contains three concrete drills and two chisels of different shapes.

Price: RUB 3,263

After all, for this model, the loads are not critical either when working with a drill with a diameter of up to 28 mm, or with non-impact bits, or during the chipping process.

Characteristics Values

DeWalt D25103K

Thanks to the price of the D25103K horizontal rotary hammer, the potential of professional equipment has become accessible to the average amateur.
This means that independent performance of a wide range of repair and finishing work will not be overshadowed by frequent engine overheating, requiring long-term rest, unstable operation of the impact mechanism (due to design features and, at the same time, an easily solvable problem in most models of inexpensive tools) and injuries received during operation. The reasons for this are, respectively:

1. low shaft speed
2. design features of the impact bolt that prevent it from jamming when operating without load
3. the presence of a safety clutch that stops the transmission of torque to the shaft immediately when the drill, chisel or lance is blocked.

Thus, domestic consumers will never lose interest in a decent branded instrument, even if it is made in China (affects only the final cost).

Like most mid-range models, the PBN 300 FRE comes in a plastic case, with an auxiliary handle, a depth stop, a set of branded bits, a chisel and a quick-release chuck for regular drills. But such possibilities as:

1. work with crowns (up to 68 mm in diameter), which allows you to minimize the time for preparing places for sockets and switches;
2. adjusting the number of revolutions, which makes it possible to avoid chipping the plaster when drilling, and correctly (without aerating the solution) mix 20-25 kg of dry mixture with water;
3. a safety clutch that reduces the risk of injury if a drill or bit gets jammed during operation of the tool, and others, indicate that this hammer drill is a professional model. And only the price reminds you that this is a middle-class instrument. Theoretically, this is the possibility of long-term use in domestic conditions. But in fact, domestic professionals use such a tool quite often. Since, with a proportionate load and timely maintenance, even the “green” series from Bosch is capable of showing decent results throughout its entire service life.

AEG KH24E

The 2009 restyling did not affect the appearance of the KH24E; the main changes were made to the “filling” of the instrument.
For example, in the updated models the impact force was slightly reduced, which increased the accuracy and duration of work. Thanks to this, this hammer drill is suitable for an amateur, because in order to use the full potential of the model, it will take more than one year and a wide range of interests (the manufacturer allows work on wood, metal, concrete) for a professional who will come up with the need for the first maintenance in about a year ( The service life of the new KH24E has increased due to the reduction in power). At the same time, each of them will appreciate the elastic coating of the handle, the ability to adjust the speed by pressing the trigger, and the presence of a quick-release chuck with a shank included in the kit.

How to choose a professional hammer drill

Professional models of rotary hammers differ from household models in power, endurance and a long period of continuous operation. To choose the best option for such a power tool, you first need to pay attention to the following characteristics:

• Impact mechanism type.
• Impact power and energy.
• Drill mounting type.
• Anti-vibration protection.
• Spindle speed.
• Brush reverse.
• Corded or cordless tool.

A professional class cannot be called a cheap tool, so the master must clearly understand what qualities the optimal model should have.

Impact mechanism type

Rotary hammers can use one of two types of impact mechanisms: pneumatic or electromechanical.

Pneumatic impact mechanism

The principle of its operation is that the piston of the drive mechanism compresses the air cushion. The second, free piston is surrounded by air on both sides. It moves forward to the striker, transferring the created force to it.

The actuator piston then moves backward. At this time, the free piston is pushed away from the striker, which moves backward. The compression of the air cushion on the other side of the free piston increases, causing the piston of the drive mechanism to stop.

Under the influence of high pressure, the free piston flies back to the firing pin at increased speed. The impact is transmitted to the equipment during the operation of the tool.

Watch the video on how a pneumatic impact mechanism works:

Important! When choosing a hammer drill for professional use, you should give preference to a pneumatic impact mechanism.

Electromechanical impact mechanism

An electromechanical system that creates impact force is often equipped with lightweight models. In such systems, the lever spring is driven by an eccentric. It moves the impact device back and forth. Through a special hammer, the force is transmitted to the equipment. The recoil is absorbed by the spring, increasing as the mechanism moves forward. This system is less durable and is not used for long-term, high loads on the tool.

Watch the video on how the electromechanical impact mechanism works:

Power and impact energy

Professional models have impact energy from 7 to 27 J. The higher this figure, the more productive and durable the tool. The power of a professional type tool is from 1 kW.

Such equipment has a wide range of functions:

• drilling holes, including those with a diameter of over 100 mm;
• drilling natural stone;
• chipping of concrete when openings widen;
• creation of grooves for laying communications.

Drill mounting type

To fix the drill in rotary hammers, quick-release fastening systems of the SDS type are used. The most common is the SDS Plus drill mounting system, but it is not used on professional hammer drills. For professional models, the mount has been improved. Power tools in this category are equipped with an SDS max type mount. Designed for operation under high shock load conditions.

Cross section of SDS Plus and SDS Max shanks:

SDS Max.

The shank diameter of the SDS max equipment is 18 mm, which makes it more reliable. The design of the cartridge has a number of features. The shank is fixed in it using 5 grooves. Often rotary hammers with SDS max operate in 2 modes: drilling with impact or only impact. Therefore, it is impossible to use a hammer drill of the presented class for simple drilling and creating precise holes.

Anti-vibration protection

Professional-grade rotary hammers are equipped with active anti-vibration protection. You can work with such a power tool all day long, taking only short breaks.

The basis of the anti-vibration system is a dynamic counterweight, which is located inside the housing of such devices. The mechanism absorbs vibrations that are transmitted to the master’s hands. This significantly reduces the likelihood of developing an occupational disease called carpal tunnel syndrome.

Household models provide the simplest passive anti-vibration protection. Therefore, it is undesirable to use such a technique in professional activities. Over time, health problems may arise.

Spindle speed and impact frequency

The rotation speed of the tool fixture depends on the spindle speed. This indicator is inversely proportional to power. Rotation is necessary to remove the cuttings generated during the drilling process from the hole.

If a master more often uses a hammer drill to drill holes, it is better to give preference to a model with an indicator of up to 2000 rpm. For drilling, a high rotation speed is not needed and a hammer drill with a spindle speed of up to 1000 rpm is suitable.

Impact frequency is one of the most important indicators of a rotary hammer. The higher this value, the faster the drilling will occur.

Electronic and brush reverse

The reverse function is provided in many modern models of professional-class rotary hammers. In this mode, the drill moves in the opposite direction, which makes it easy to remove it from any material.

The following types of reverse are used in rotary hammers:

• Electronic. The position of the brushes does not change with this type of reverse. The direction of torque is changed electronically. Because of this, power drops and the brushes wear out faster. Electronic reverse is used on inexpensive models of household periorators.
• Brush. This is a more advanced reverse system. Switching is done by turning the brushes, which avoids a drop in power. The mechanism is more complex, which increases the cost of the equipment. But for professional use, it is more advisable to choose brush reverse.

Corded or cordless tool

Professional builders and repairmen have to work in different conditions. If the area is small and has a stationary power supply system, it is better to give preference to network models.

Cordless hammer drills are used in facilities where there is no access to the power grid. Such models are used when performing work at heights in confined spaces. Also, a cordless hammer drill is more convenient to use if you need to drill holes along a long fence or building facade.

The performance of a professional power tool with a battery is not inferior to some mains models. The only drawback of battery technology is the limited operating time. Therefore, it is better to purchase models with two batteries or purchase another battery additionally. While one battery is being charged, you can continue working.

A hammer drill with a battery is chosen by installers of ventilation, windows, air conditioners, and other workers who travel to various sites.

Which hammer drill to buy

When choosing a tool, decide how often and what tasks you will solve using a hammer drill - the class of suitable equipment (household or professional) will depend on this.

For home use, preparing small holes and working with easily destructible materials, an inexpensive hammer drill that produces about 2-3 J (we do not recommend considering purchasing less). The optimal impact frequency is in the range of 4000-4500 min-1 .

The engine power for a rotary hammer is not so important, but its reserve will allow the tool to work without overload and not heat up so quickly. , immediately look for a model with a power of at least 800-1000 W. You can even limit yourself to purchasing a battery-powered device.

Serious repair and construction work, when you have to drive a tool for several hours every day, will require you to look for a higher-class hammer drill. For most craftsmen, an impact power of 5-7 J , which will allow them to easily cope even with reinforced concrete. The power consumption of the tool can be in the range of 1000-1200 W , weight - from 5 kg .

Professionals working with complex (strong and dense) materials and capital structures will need a minimum of 10 J. This will already be a heavy hammer drill with a power of at least 1200-1500 W and chambered for SDS-Max.
