In a private house, a chainsaw is not the best handy tool: requires regular refueling, maintenance of the carburetor and air filter, and the resource of a high-speed two-stroke engine, especially on budget Chinese models, is far from ideal. But most of the work performed by the saw in such conditions takes place not far from the outlet - it is enough to stretch the extension cord outside to be able to use the electric saw. The electric motor does not need refueling, its resource is an order of magnitude higher than that of a gasoline one, besides, the owner gets rid of smoke, roar and vibrations, which are inevitable for a gas tool. If the saw is also battery-powered, then binding to the outlet can be avoided.
Well, it's worth seeing which chain saws can be called the best in 2017-2018. Given the variety of models, we will divide them into five categories:
- Amateur electric saws is the budget segment of the market, simple tools Chinese production. Battery Models We will not consider the lower segment: here you will immediately have to sacrifice either the quality of the battery or performance. Feature power saws - this is the lack of a clear separation in terms of power and tire length, like gasoline ones: what an amateur, what a professional power saw will have similar characteristics.
- AT middle segment models of electric saws are presented, which, if necessary, will be capable of long-term work - this implies greater attention to both engine cooling and oil pump reliability. Battery Models this segment in terms of performance will be lower, but will already show decent autonomy.
- Professional chain saws both network and rechargeable, are designed with the expectation of long-term work with maximum efficiency: this is not only the quality of materials and workmanship, but also thoughtful ergonomics, without which a professional tool cannot be considered as such.
Ranking of the best electric chain saws 2018
For any male representative, a good chain saw will be useful in the household, regardless of where it will be used at home or in the country. If you need to prepare firewood, carry out construction work, work on suburban area, then the chain saw is the perfect helper. The main thing is to choose when buying quality tool, which can last for many years and will delight you with impeccable work.
When choosing a tool, you need to take into account a lot of important parameters for you, ranging from power to the safety of the device. If the device is required for simple jobs on the site, then you can give preference to low power, but if serious work is ahead, then it is necessary that the engine power allows for uninterrupted operation. That is, for periodic use, a model with a power of 1.5 to 2 kW is quite suitable. For frequent it is worth choosing from 2.5 kW and above.
The next selection criteria are engine location and tire length.
The location of the engine is of two variations: transverse and longitudinal. With a transverse arrangement, the center of gravity of the device shifts, respectively, this affects the ergonomics, since when using the tool you will often have to align the cut. The longitudinal placement option is more convenient, but the price of such devices will be higher.
Regarding the length of the bar, this parameter affects the maximum section of the workpiece, sawn in one go. For professional use optimal length from 50 cm to 70 cm. For domestic needs, a length of 40 cm is quite suitable. The longer the tire, the larger the diameter of the tree it can cut. But at the same time, a large tire has decent resistance to a rotating motor, so the length must match the power.
Also, when buying a chain saw, look for additional features that can simplify the operation of the tool. These features include the presence of a soft descent, protection against accidental activation, protection against overheating and a chain brake.
You should also pay attention to the way the chain is tensioned. There are two options here: key and without the use of wrenches. On the one hand, this is very convenient when there is no need to carry keys with you and you can tighten everything on the saw during operation. On the other hand, it is believed that the nut tension is safer and more reliable, since the keyless tension mechanism can loosen and fly off during operation.

What power saw do you like?
If you live in your own house or have a dacha, then a good chainsaw will definitely come in handy for you! A saw is a necessary item for cutting firewood, pruning branches, or cutting beams for construction. Previously, they used a hand saw, a lot of time and effort was spent on it. Now everything is much simpler, the use of a chainsaw greatly facilitates the work. The only question is which chainsaw to choose, because modern market provides a considerable number of types of this tool, as well as companies that manufacture them. To do right choice regarding the model and manufacturer of the chainsaw, I propose to consider this issue in detail below.
Chainsaw types
Amateur chainsaw
Used for small jobs . The amateur chainsaw has low power and is intended exclusively for operating it in the garden. This type of tool can be used for no more than 45 minutes a day and has a power of 2kW. The low profile chain used on this chainsaw helps to reduce vibration during operation. The disadvantage of this circuit is its insufficient performance.
This tool is comfortable and lightweight, during its use the hands are not particularly loaded. For work in the garden, the tool justifies itself quite well, such tasks as pruning branches, chopping firewood and small construction work will be completely mastered by this chainsaw.
Semi-professional chainsaws
The power of models of this class is able to cope with both construction work and logging. But the minus of these models lies in their short-term operation, using the tool for many hours every day hello to an early breakdown. Chainsaws of this class have a power of 2.5 kW, their weight is 5-6 kg.
For building a house, namely: laying floors, creating a roof frame, as well as for building a bath, this unit is ideal, and its operation in the garden will save a lot of your time.
Professional chainsaws for felling trees
These tools are quite powerful (2.7-6 kW), they are designed for many hours of daily use. Such a chainsaw is often not purchased for private use, unless you need it for a full-scale construction and cutting firewood for the entire winter season. Such chainsaws are bought mainly for felling forests, since this tool is quite wear-resistant and is designed for cutting very thick trees and can withstand about 2000 hours.
For home use in a professional chainsaw, there is little need because without certain skills, it is quite difficult to use. Its weight exceeds 6 kg, and the vibration is very noticeable, these qualities create a lot of discomfort when working for an inexperienced person.
What power to choose a chainsaw
Power is the main indicator of the saw, it determines the speed of sawing and depth. To understand how much power you need the unit, it is important to decide for what purpose you are going to purchase it. If the use of the saw does not involve sawing very thick trees, and you are not going to use it every day for many hours, then for ordinary work in the garden you will be fine with a tool with a power of up to 2 kW.
Important ! The greater the power of the unit, the more difficult it is to control it.
saw set
When choosing a saw, there are many factors to consider, one of which is the capabilities of the saw set.
Consider all types of saw tires:
- Narrow flat. Such tires are put on non-professional chainsaws. It works in conjunction with a low profile chain and there is virtually no risk of injury while using the machine.
- Lightweight. It consists of two plates fastened with polyamide. This design significantly reduces total weight the entire saw, and this fact is important, since the process of controlling the unit is greatly simplified. For example, if you work at height, it can be quite difficult to cope with a heavy chainsaw.
- With replaceable heads. Designed for professional chainsaws with high power, specially designed for many hours and daily work.
Also, do not forget about the length of the bar, which should correspond to the power of the saw. The long bar allows for a deep cut, making it easier to handle wide logs. The discrepancy between the length of the tire and the engine power is fraught with the fact that, with insufficient power of the unit, the sawing speed drops significantly, since the rotation of the crankshaft consumes a lot of energy produced by the engine. The sawing process will be slow, and fuel consumption will be large, as well as the fate of the engine in this situation is sad. It will wear out soon. Pay attention to the instructions, it will indicate the recommended tire length for your unit.
Important ! You can not use the tire more than indicated in the instructions, smaller size allowed, although not recommended.
Chainsaw chain
The chain, or rather, its pitch, greatly affects the sawing speed. When choosing a unit, you need to know that there are three types of step:
- 0.325";
- 38 inches;
- 0.404 in.
Household chains have a pitch of 0.325 inches. Chains with this pitch are characterized by almost imperceptible vibration, and are not designed for continuous operation. If it is cut for a long time, it will lose its cutting ability very quickly.
Chains with a pitch of 38 inches and 0.404 inches put on powerful units. Designed for very long work and sawing thick logs. But even such chains are not able to cope with frozen and dirty trunks. For such work, there are chains in which there are carbide solderings.
It is important to understand that all chainsaw components must be from the same manufacturer, since parts different brands are simply incompatible. Let's say if you have a Stihl unit, then you can replace parts in it, only of the same brand.
Kickback protection
A great danger for a person working with the unit is the “backstroke”, that is, during operation, the saw can strongly bounce in the direction of the worker. The tool may bounce when the end of the bar hits the wood. Therefore, when choosing a chainsaw, it is extremely important to find out if the saw you are interested in has a kickback protection.
There are two types of protection, one of them is a special brake, and the other is an additional shield. The brake is more commonly used, it is a lever that has two positions. When starting the unit, the lever switches, becoming closer to the hand, when kickback the hand itself presses the lever, which switches it to a mode in which the chain stops.
An additional shield is designed to protect the hands of the worker from contact with the cutting part of the tool. It is installed at the end of the saw set. The Swedes do not use such protection, as they always cut trees with the end of the headset.
Anti-vibration protection
When you choose a chainsaw, ask the seller to give you the included tool in your hands to check its vibration. In low-power units, the vibration is light, but if the tool has anti-vibration protection, unpleasant vibrations disappear.
Vibration protection is rubber pads installed between the body of the saw and the handles.
You can not use protection only if you are not going to operate the unit every day for many hours. The vibration emitted by the tool negatively affects the hands, which can later cause their disease.
Chainsaw in female hands
Usually men use a chainsaw, but sometimes women also want to learn how to work with a tool. For women, only a saw with low power is suitable, because it is not heavy and has a low level of vibration. professional tool a woman simply can not hold in her hands.
Perfect for women, it is light and has no vibration. But you can work with it only if there is a source of electricity nearby.
What brand to choose a chainsaw
And so we figured out the main components of a chainsaw, and also determined which type of unit is more suitable for home use. But remains open question which measure to give preference to. the best firms are: Husqvarna and Stihl, below we will briefly consider their pros and cons.
Husqvarna
The main advantages of the Husqvarna unit:
- The bar is longer than other tools (38cm) ;
- Easy start;
- Chain pitch 3.25.
Flaws:
- Does not show the level of oil and gasoline;
- Hypersensitivity to bad gasoline;
- Expensive service.
Stihl
Advantages of the Stihl saw:
- Shows the level of oil and gasoline;
- Not sensitive to the quality of gasoline;
- Much cheaper to maintain.
Flaws:
- The air filter clogs up quickly.
Video which chainsaw is better Husqvarna or Stihl
Take away the saws from mankind and progress will stop. This statement is not a joke. Without a tool capable of cutting wood and metal, concrete and stone, functioning is impossible. industrial enterprises and other areas of commodity production.
In the household, too, it is not possible to do without saws. Every man has at least one hacksaw, and good master you can find a whole arsenal of "toothy helpers."
We will look at the most common types of saws to get an idea of their working capabilities and application features.
It all started with a simple hacksaw
It is this saw that is the ancestor of the family hand tool designed for wood processing. As soon as the first ingot of iron was smelted, a person had the idea to forge a tool for cultivating the earth from it.
It can be assumed that the ax became the second after the hoe. The third was probably a saw with a handle, known to us today as a hacksaw. Over the centuries that have passed since its invention, she has acquired numerous "brothers and sisters" who perform dozens of different jobs.
The accepted classification divides this type of hand saws into two groups:
- Hacksaws for wood;
- Hacksaws for metal.
Depending on the cutting direction, hand saws for wood are divided into three categories:
- For ripping cutting;
- For cross cutting;
- Universal (longitudinal-transverse).
The difference between them is in the shape of the cutting teeth: on a rip saw they are inclined forward, while on a crosscut saw they are straight.
Universal hacksaw tooth also tilted forward, but has a special sharpening. It allows you to cut along and across the fibers.
By appointment, hand saws are divided into several types:
- Classic hacksaws (transverse or longitudinal cutting);
- Circular saws (for cutting holes);
- Spike saws (for cutting connecting spikes).
When choosing hand saw An important role is played not only by the shape, but also by the size of the teeth.
There are three types of incisors:
- Small tooth - 2.0-2.5 mm (for high-precision sawing and cutting of small products);
- Medium tooth - 3.0-3.5 mm (for medium-sized parts);
- Large tooth - 4.0-6.0 mm (for rough cutting of timber and logs).
The international classification divides hacksaws not by the height of the teeth, but by their number per 1 inch of the cutting blade. This standard has taken root with us, so do not be surprised if you see the letters PPI or TPI on the tool label. The number behind them is the number of teeth per inch of length. The larger it is, the smaller the tooth (eg PPI 8 or TPI 14).
Today on the market you can see modernized look hacksaw. They are easy to distinguish by the gaps cut in the canvas. As a result, the teeth are arranged in groups of 6-7 pieces.
This tool is designed for cutting raw wood. The gaps between the teeth are needed so that wet chips do not clog the cut and are easily removed during operation.
In addition to the usual hand saws, users today are offered an electrified version of the tool. A powerful electric saw can easily handle a large amount of lumber cutting work without tiring the owner too much.
The versatility of its application is achieved due to the configuration of saws with different length and blade width and tooth size. This allows you to successfully work not only on wood, but also on plastic and metal. Another name for this tool is a reciprocating saw.
The main parameter characterizing the capabilities of electric cutters is power. It is in the range from 400 to 1600 watts. The depth of cut directly depends on it, which ranges from 90 mm for household to 200 mm for professional models.
Hand tools for metal processing are not so diverse. There is only one type of hand saw that can cut this material. Its working body is a wide or narrow blade with fine hardened teeth. It is inserted into the bow holder and tightened with a screw.
Circular saws
The idea to replace the reciprocating movement of the cutting blade with a circular one can rightly be called revolutionary. It arose after the advent of the electric motor and significantly increased the speed and productivity of work.
A typical representative of a tool that uses this principle is a circular saw. Its main advantages - mobility and high power overshadowed the modest capabilities of a hand hacksaw.
By design, circular electric saws are divided into gear and gearless. In the first case, the electric motor rotates the gear reducer, on the shaft of which there is a saw blade. The second option is to mount the disk directly on the motor rotor shaft. Both designs have a mechanism for adjusting the depth of cut and the angle of inclination.
The advantage of gear mechanisms is the ability to perform deeper cuts. Gearless saws have two advantages: lighter weight and affordable price.
In the passive, they are inclined against the course (negative sharpening angle).
Passive discs are indispensable when cutting metal. Active ones are used for wood processing. The disc teeth can be hard-faced. They make it possible to cut harder materials, but negatively affect the cleanliness of the cut.
The working capabilities of the tool depend on the power of the electric motor (from 0.65 to 2.5 kW). Manufacturers also indicate the maximum depth of cut that a circular saw can perform (from 25 to 85 mm).
A variation of this power tool is a circular saw, which is mounted on a fixed frame. Such a solution allows high precision cut long and wide material.
Some manufacturers offer an interesting compromise - hand-held circular saws that can be turned over and fixed on the table, turning it into a stationary "circular saw".
When answering the question of what kind of saws are, it is impossible not to mention trimming devices. In this case circular saw mounted on a pendulum arm. As a bed, a rotary plate with a conveyor (angular) marking is used.
The advantages of a miter saw over a circular saw are obvious: you can make perfectly precise cross cuts at any angle. This operation is especially important when docking different wooden parts(platband, plinth, lining, timber).
Chain saws
Often, when working with wood, it is not the cleanliness and accuracy of the cut that is important, but its depth. This is precisely the task that the chain saw solves - a powerful device with an electric or gasoline engine, designed for felling trees and cutting firewood.
It has two main interrelated technical parameters:
- Engine power;
- Tire length.
A tire is called two flat plates interconnected with a small gap for installing a saw chain. At one end it has a driven sprocket, and at the other there are cutouts for the tensioner.
Power chain saws with electric drive range from 1.5 to 4 kW. When choosing a device for household work on the site, it is better to stop at a power of 1.5 to 2 kW with a saw bar length of 30 to 40 cm. This is quite enough not only for sanitary pruning garden, but also for firewood.
If necessary, such a tool can dissolve a board, log or beam, although High Quality and you will not get cutting accuracy.
There are two subspecies of chain saws:
- With lateral (transverse) placement of the engine;
- With longitudinal motor mounting.
The first type is simpler in design and cheaper in price. But the second one is more convenient to use, although more expensive due to the introduction of a gearbox into the design.
The main thing that gives the owner a chainsaw is autonomy. With such a tool, you can go to the forest and cut firewood there. You will have to pay a price for such a significant plus: chainsaws are more complex in design than electric ones. This difference is especially felt when buying a cheap "but-hire" device. Problems with starting, carburetor, rings and candles are frequent companions of such a purchase. Therefore, it is better to buy a more expensive one. chainsaw than to lose money when operating an economy option.
Electric jigsaw
Circular saws and chain saws cannot replace a device that uses a narrow blade that moves up and down at high speed.
Thanks to this arrangement of the working body, the jigsaw allows you to quickly and accurately cut curved flat parts. Plywood, ceramics and plastic, OSB and soft metal - all this can be cut with a good jigsaw with a quality file.
Electric jigsaw
For each material, manufacturers make special saws that differ both in the inclination of the teeth and in their frequency.
For example, wood is better cut with a file with a large tooth. FROM sheet metal a canvas with a fine jagged notch will confidently cope. We will not give special recommendations for choosing saws for electric jigsaws, since the manufacturer indicates the recommended type of material on each of them.
Main technical specifications electric jigsaw - engine power, saw blade stroke rate and maximum cutting depth (indicated for different materials).
For household models these parameters are within the following limits:
- Power from 400 to 900 W.;
- Stroke frequency (with the possibility of smooth adjustment from 0 to 3000 rpm);
- Cutting depth (wood - 45-80 mm, steel from 4 to 20 mm).
A useful option for a jigsaw is a laser pointer. It helps to clearly see the direction of the cut when the marking line is hidden under a layer of sawdust. Choosing electric jigsaw, pay Special attention nozzle in which the file is attached. It should provide the most reliable clamp. Otherwise, the file will regularly jump out of its weak "embrace".
A logical development of the jigsaw design was a compact band saw. Its working body is a closed steel tape with teeth, which is rotated by an electric motor.
Sawing with it is easier than working with a jigsaw, which vibrates strongly and strives to escape from your hands. The cleanliness and precision of the cut of the band saw is perfect. This not only reduces waste, but also produces a cut surface that does not need to be sanded.
The workpiece here can be held with two hands, which increases the accuracy of operations when cutting curved elements.
The main indicator of band saws for wood is the depth of cut, which can be from 8 to 50 cm. An electric jigsaw and a circular saw are not able to cut such a thick material.
The remaining characteristics refer to cutting blades.
There are two categories here:
- Carbon saws (manufactured steel C75 and analogues);
- Alloyed saw blades made of D6A steel (have increased wear resistance and resistance to alternating loads).
Depending on the manufacturing technology and hardening of the cutting teeth, the blades are divided into two types:
- Saw bands with notched non-hardened teeth;
- Blades with cut hardened teeth.
The advantages of saws of the first type are low cost and the ability to cut wood with foreign inclusions: nails, stones, fragments. Such a blade works with small sawing volumes (2-4 m3 per day) and at a minimum feed rate (6-10 meters per minute).
The main advantage of a saw blade with a hardened tooth is its high wear resistance (2 times higher than that of saw blades with non-hardened cutters). Disadvantages - high cost and sensitivity to foreign inclusions.
The remaining parameters of band saws are reduced to a simple list:
- Web width;
- Number of teeth per length inch (TPI).
For standard wood sawing jobs, a 1/2″ wide band is optimal. Narrower blades (3/8") are used for curly cutting.
The number of teeth of the cutting belt directly affects the evenness of the cut (the more teeth, the smoother the cut). Rough saw blades(2.3 TPI) is used for cutting wood and logs up to 200 mm thick. For cleaner work use saws with 6 TPI, and for precise cutting use size 10-14 TPI. Optimal size, which achieves high performance and good quality cut - 8 TPI.
A table band saw for metal is similar in design to a wood cutting device. However, its capabilities are more modest. This tool can only perform cross cutting of rolled steel (pipes, angle bars, fittings, channel bars) at different angles.
There are a very small number of tools that should always be at hand diligent host. One of them - . Cutting branches in the garden at the cottage, fixing the fence, furniture, door - all these are the little things of everyday life that are difficult to do without a high-quality electric saw. Basically, this simple tool is designed to perform versatile tasks for cleaning the garden or for preparing firewood, it is indispensable for those who permanently live in the country or have a private house With big garden. With a high-quality and convenient electric saw, you can easily cut a small tree trunk or make a blank for a future element. wooden decor. In some cases, such a unit can be used as a brush cutter. The main advantage of the electric saw is the complete absence of exhaust gases that appear after the combustion of fuel. Therefore, electric saws can be safely used indoors. Choosing the right model of electric chain saw is a very serious step. There are many different criteria, on which the power and quality of work performance depend. so that you can choose the perfect suitable model, we recommend that you consider the five main parameters that are responsible for the performance of a particular model of electric saw.
What tire length is enough?
When buying an electric chain saw (however, like any other), you first need to pay attention to working length tires. Naturally, the longer the tire of the model, the larger the diameter of the tree trunk it can cut. It is important to note that a large tire has an increased resistance to engine torque. Therefore, the length must necessarily correspond to the power of the motor.
As a rule, manufacturers immediately technical specifications models indicate the size of a valid tire. Is it possible to install more authentic? Of course, but this is fraught with engine failure. A low engine power may not withstand overloads, in addition, energy costs will increase, and you will need to put in a lot more effort to cut wood.
For household power saws, the bar length generally ranges from 25 to 40 cm. Very short bars are installed quite rarely - this is impractical. It is customary to consider electric saws with a 35 cm bar or with a 40 cm bar as optimal. In cases where two saw models have the same power, but different tires, it is better to take the model with a shorter tire. It will cut boards much faster, and it is more convenient to work with.
Models that are used at the semi-professional level have 45 cm and 50 cm tires. They are more powerful and designed for long-term active use in work with different type wood, including very hard ones - oak, clear, acacia.
Professional units that are bought for felling and cutting thick tree trunks are a special category of power saws. For them, the length of the bus is very important, since it directly determines the performance. For quick and productive work on felling trees, it is worth taking an electric saw with a tire, the parameters of which range from 60 to 90 cm.
What is the chain pitch?
A saw chain is a set of riveted links. And the chain pitch is the distance between three adjacent rivets that stand side by side, divided in half. This is the main parameter that determines the cutting ability and quality of future work. Electric chain saws have three digital designations for the chain pitch - 0.325 *, 1/4 * and 0.375 *, which is quite often denoted by 3/8 *.
An electric chain saw with a chain pitch of 0.325 * and 1/4 *, as a rule, is an inexpensive tool intended for amateur use. Such chains are called low-profile, they have reduced vibration, they cut neatly, without jagged edges, but they easily dull under prolonged loads. It is better to use low profile chains for fast and operational work in the garden or for repairing wooden products.
3/8” pitch chains are the most common, with more than 80% of the most popular brands equipping their tools with them. Such saws are designed for active use, both in everyday life and in professional enterprises. Most of these are professional models, powerful and versatile, designed to perform diverse tasks. Their power and technical parameters allow for active work for a long period of time.
A large chain pitch allows you to quickly cut the desired tree trunk, but when using such a chain, the edges of the tree turn out to be very disheveled. Therefore, chains with a large pitch are more often used for rough work. In addition, the minus of such saws is increased vibration. But their unsurpassed plus is high productivity.
The location of the motor is an amateur
There are two types of motor locations on electric saws, and you can easily identify them at a glance at the tool:
- transverse- the axis of the engine of the model is perpendicular to the chain;
- longitudinal- the axle runs along the tire.
The main advantages of the transverse engine arrangement include:
- 100% transmission of the power of the running engine to the circuit;
- reliable performance gearbox gears;
- in spite of everything, such saws are more convenient to use;
- no recoil when turned on.
But, unfortunately, we should not forget the disadvantages of such a tool:
- More heavy hangman;
- when turned on, the saw can sharply “bounce” to the side;
- the gear used in the gearbox eats up some of the power, reducing the productivity of the saw.
Much depends on power.
The power of any saw is the speed at which it pulls the saw chain while cutting. Power also affects the depth of cut. That is, the higher the power, the faster and deeper the saw cuts.
It is clear that the nature of its future work - amateur or professional - depends on the power of the electric saw. Therefore, choosing a model, first of all, it is necessary to determine the volume and nature of future work. You should not choose a model more powerful than you need, because it is heavier, draws more electricity, and will cause you discomfort during work: fatigue, back pain. For small jobs on the personal plot it is enough to choose an economical saw with a power of 1.5-2 kW. Models with a power of 2.2-2.5 kW are semi-professional and professional units designed specifically for long-term work, easy sawing solid wood. There are even more powerful production electric saws - 9 kW of power, they are very effective when felling trees, they can work from the mains or from a high-quality diesel or gasoline generator.
