The most important things about electric chain saws for wood
This is a popular power tool in carpentry workshops, construction sites, and household work at home. The design is similar to chainsaws, but with an electric motor instead of an internal combustion engine. These are the advantages over chainsaws:
- no exhaust gases, you can work in enclosed spaces without the risk of poisoning.
- There is no roar from the operation of the internal combustion engine, you can work without disturbing others.
- always ready for work, do not require preparation of the gasoline/oil fuel mixture.
Disadvantages compared to gasoline saws:
- Lower revs and power.
- Depends on the presence of an electrical outlet nearby (does not apply to battery models).
Otherwise, they do the same work as gasoline saws: they cut any workpieces, including large ones - beams, logs, blocks, slabs, carriages, boards, etc. When using special chains, you can saw through piles of cardboard, linoleum, ice and even hard materials, including concrete.
Main parts: engine, body and saw set - bar and chain. The chain is sharpened and lubricated in the same way as on all chain saws.
Advantages over circular saws, reciprocating saws and jigsaws: the ability to cut workpieces of any depth (thickness), even stacks. The length of the cut is significant and depends on the length of the tire.
Despite their simplicity and compactness, modern electric chain saws incorporate the latest developments in the field of mechanics and electronics - soft start, speed control, overload protection, etc.
Classes
Electric chain saws are divided into several groups: household, professional or industrial, and as a subtype - battery-powered.
Household
These include the cheapest, budget models with minimum and average power and service life. Well suited for occasional housework. They are also successfully used as an auxiliary tool at construction sites and in workshops. If you don't need to run an entire shift of power saws for months or years, household models from brands with a good reputation for quality can serve well.
Approximate characteristics of household options.
- Power – from 1500 to 2500 W.
- Weight from 3.3 to 7.5 kg.
- Price for mid-2021 – from 3,000 to 12,000 rubles.
Moreover, in terms of characteristics, there are no clear boundaries between household and professional models. There are models that are positioned.
There are lightweight models that are highly reliable and durable and can be used professionally for many years. But they can't be cheap. As a result, the main feature of household models is low and average price and power.

Professional or industrial
These are electric saws that are designed to be used for many hours per shift over several years. They are reliable, hardy and unpretentious.
As a rule, these are power saws from well-known brands with a good reputation for the quality of their products. Industrial chain saws are sometimes labeled without a brand name. For example, EHR 3.0 -2.
A long service life does not negate the regular replacement of individual parts - chains, tires, sprockets. The latter are changed less often, but the saw set (chains and bar) on all chain saws is practically a consumable item (subject to regular replacement).
Depending on production and professional needs, tools of different power are used. For construction and finishing work, carpentry work, carpentry workshops, where most of the workpieces are small and medium in size, medium power is sufficient. At sawmills and logging sites, where you have to cut stacks and logs, powerful options do a better job.
Average parameters of professional electric saws:
- Power from 1800 to 2700 W (industrial - up to 8000 W).
- Weight from 4.5 to 6 – 7 kg (and higher for industrial ones).
- The price range is wide, as of mid-2021 - from 8-9 to 150 thousand rubles.
Industrial and professional electric chain saws are also used for longitudinal sawing, manually or on sawmill stands, including homemade ones. For this, a special saw set is used:
- Narrower bar and chain.
- The sharpening angle of the chain tooth is 10 degrees.

Rechargeable
No power extension cord required. They can work completely autonomously anywhere, until the batteries run out. More convenient than networked options for pruning gardens and construction work at heights, where the cord will get tangled and interfere.
Flaws:
- Low power.
- The need to regularly charge batteries.
Most models use modern brushless motors, which increases service life. The power of such electric saws is not indicated in W, only the battery voltage (12, 16, 18 Volts). The main parameters by which they are assessed:
- Weight, from 2 to 6 kg.
- Tire length, from 25 to 40 cm.
- Chain speed – from 4 to 20 m/sec.
The large difference in chain speed in different models is due to design features. When you gain speed, you lose strength. Some manufacturers rely on chain speed, others on strength.
High speed models are better suited for tree trimming. Reason: sawing branches and branches must be started at high speed, then there is less chance that a chain tooth will catch on a thin branch without sawing it, and the chain will get stuck. By entering a branch at high speed, the chain is less likely to get stuck.

Hand-held circular saws
An indispensable tool at a construction site is a hand-held circular saw for wood. It is capable of cutting sheet material (plywood, various wood-based boards, metal), and with its help it is easy to cut boards of small thickness.
The circular saw is universal. It copes equally well with the transverse cutting of wood; it can be used to make precise longitudinal cuts. For any material and method of work, it is easy to choose a disc with suitable parameters. Thanks to a properly selected saw blade, the saw will provide a thin, even cut with clean, smooth edges.
When choosing this power tool, you need to take into account its main characteristics.
Engine power. The more power, the more “omnivorous” the saw, but also the higher its cost.
Rotation speed (rpm). The higher this indicator, the harder the material is on the saw teeth and the cleaner the resulting cut.
Depth of cut. Maximum disk output. In household devices this indicator is at the level of 50-65 mm, in professional models – up to 130 mm.
Among other things, when choosing a circular saw, you should pay attention to its weight. The mini-tool is highly maneuverable; when working with it, you do not need to exert excessive effort, but the low weight will certainly affect the power indicators.
What characteristics should you choose based on?
All models, even of the same brand, differ from each other in both significant and minor details. Below are the main qualities, the most important first. Then in descending order.
Engine power and location
The more powerful the engine, the easier the electric saw cuts the material. If two models have tires 40 cm long, but engines are 1.2 kW and 2.2 kW, both are capable of sawing a stack 35 cm long. But the more powerful one will do this easier, faster, without overheating and overload, which means it will last longer.
There is a pattern - the more powerful the electric saw, the heavier and more expensive it is, and consumes more energy.
Therefore, when choosing, you should choose the option that is suitable for the upcoming work . There is no point in sawing medium-sized workpieces with a heavy tool. Medium power chain saws are the most versatile.
Power type
Comparisons of corded and cordless electric saws are given above. Battery-powered options are chosen without hesitation when you need to work far from electrical outlets, at heights, or in hard-to-reach places.
This includes pruning the garden, preparing firewood for a fire in the forest, and construction work, especially at heights. That is, wherever there is no network electricity nearby or the wire will seriously complicate work.
Due to the weakness of the engine, the saw set on such a tool must always be in good condition. If with a powerful engine you can saw with a slightly dull chain, deformation and slight jamming of the chain in the tire groove, then the battery version will lose a significant part of the power and capabilities.
Kerf dimensions
What diameter of a log, or how wide a stack can be sawed in one pass, depends on the length of the bar and chain (saw set). A 25 cm long tire is capable of sawing a log with a diameter of 20-24 cm and a stack of the same width. Why not 25 cm - it’s better if the tip of the bar extends outward, so sawdust is easier to remove from the cut.
In this case, the height of the stack can be any. Therefore, the depth of cut for such a tool is not limited.
The thickness of the cut for different models is from 6 to 10 mm, always slightly thicker than the thickness of the saw set. A thin cut is preferable - when sawing, there is less wood resistance, higher cutting speed and accuracy.
Availability of oil tank and its capacity
The chain requires lubrication during operation. That's why all models have an oil tank. The volume of the oil tank is specified in the operating instructions for each model (approximately from 100 to 180 ml). The larger it is, the less often you have to fill in oil.
An enlarged tank increases the size and weight of the tool. Taking into account the fact that the sizes of the tanks differ slightly, this parameter is of little importance when choosing.
Power cord
In many cases, work is carried out at a distance from the outlet. Therefore, you have to use an extension cord. The longer the wire of the saw itself, the more often an extension cord is not required. A wire 1.5-2 m long can be considered an advantage. But it turns into a disadvantage when storing and transporting the instrument.
It is easier to put a power saw with a short cord of 30-50 cm in a box on a shelf. No need to wind and unwind the cord. Long extension cords are wound on a drum or left permanently in place, making them easier to handle. There is no point in installing a drum under the cord on a hand-held instrument (dimensions, weight). That's why most models have short power cords.

Modern electric saws compete well with gasoline models. But you need to choose your option thoughtfully and without haste.
Additional functions
Modern electric chain saws are equipped with electronic and mechanical safety systems for the operator and the mechanism itself. Some options are not available on all models.
overheat protection
An electronic device turns off the electric motor at critical overloads. With such a device, the engine will not smoke or burn out if, for example, the chain is caught in a cut or the engine overheats. Useful feature. But on budget models it may have its drawback - frequent shutdowns even under normal loads. On quality saws such “excessive vigilance” does not occur.
Safety
All electric chain saws, without exception, are equipped with basic safety systems. This is primarily a brake that stops the chain even if the engine is turned on. Until the operator turns it off, the chain will not spin. The brake is turned on and off with a protective handle, which simultaneously blocks the space between the hands and the chain.
Adjusting chain tension
It is impossible to use this tool without adjusting the tension, therefore the function is present on all models without exception. The principle of adjustment is the same everywhere.
The design solution may differ - loosening the cover and tightening it with or without a wrench, with a built-in regulator. The regulator is more convenient, no additional key is needed. The plastic regulator cap of quality brands is reliable. Not always with budget ones, so for them tightening with a wrench is easier and more reliable.
In general, the design of the chain tensioning system is not a decisive criterion when choosing a model. More important is the strength of threads and metals. When purchasing, it is impossible to visually evaluate this moment. Only indirectly, by brand reputation.
Smooth start
With this function, the chain does not gain momentum immediately, but smoothly. The system protects the electrical network from overloads when starting the electric motor. Plus, during a soft start there is time to correctly route the chain, which increases safety. The disadvantage of a soft start is that it takes several seconds until the engine reaches full speed. For those who are used to normal starting, this may be annoying at first.
How to choose a chain saw
Before choosing an electric chain saw, you need to study its electric motor characteristics and safety system. At the same time, there is no need to save on the power of the tool, since work productivity largely depends on this parameter.
You also need to select a power saw according to the place of use. Since the characteristics of an electric saw for the home are very different from saws used in professional activities.
In addition, one of the most important requirements for all devices is their ergonomics. Therefore, choose the option in which the electric saw will fit comfortably in your hands. Otherwise, you will get tired quickly, and your work productivity will be very low.
Ergonomics
Most models are made “in length”. Only some have a transverse electric motor. For the user, the overall ergonomics, dimensions and weight of the tool are important.
It is important how the electric saw “sits in your hands.” It is advisable to hold the instrument in your hands before purchasing. Is there an overweight in one direction, is the instrument too heavy?
Impressive weight may mean using reliable parts of the required thickness, without trying to save on cost and reduce weight.
But “heavy” here does not always mean “reliable”. The ability of Japanese designers to make miniature, reliable parts is well known. In addition, heavy weight may mean that heavy ferrous metal was used instead of light and expensive magnesium-aluminum alloys. As a result, you cannot judge the quality of an electric saw by its weight. But a heavy tool is harder to work with.
Equipment
Together with the electric saw, the buyer receives:
- Tire.
- Chain.
- A screwdriver key for tensioning the chain (for models with a key tensioner).
- Operating instructions.
An example of a complete set of an electric chain saw from Champion; in addition, a plastic container for storing oil is supplied with the tool.
Rating of the best models
Below are several high-quality and reliable electric saws that deserve the buyer's attention.

Popular manufacturers
Among the many brands of electric chainsaws, the most popular are Makita, Huter and Patriot. This does not mean that you should only buy tools from these manufacturers, but they are purchased more often.
Today, none of these companies can be said to be, for example, German or American. All these companies are global. Production facilities, design bureaus, sales offices, and service centers are located all over the world, including in the Russian Federation. However, everyone has their own national origin. Makita started in Japan, Patriot in the USA, Hooter in Germany.
The easiest way to understand which country a particular electric saw was made in is when purchasing a Makita tool. After the serial number on the nameplate there is a letter designation, which is deciphered according to the following table:
- E – made in Japan.
- R – Europe, Romania.
- Y or K - made in China.
- D – made in Germany.
Makita is also produced in the USA (letter A) and England (G). But Makita products are not supplied to Russian markets from these countries.
Today, production around the world is most often controlled by engineers and designers from these countries. Therefore, all brands still retain traditional Japanese miniature and thoroughness, German reliability, American rationalism and convenience.
