What is a circular saw for wood?

To choose the right circular saw for wood, you should start with its essence. This tool is a cross between a simple electronic jigsaw and a chainsaw that can cut thick tree trunks..

The equipment is intended for use both at work by professionals and at home. The cuts are accurate and fast. mowing line using the presented technique is straight and can be produced in wood of various thicknesses.

Circular saws can cut wood in a variety of configurations. This equipment can cut various decorative elements on the material, but the operating time will be longer than that of a low-power jigsaw..

Comparing the work of the presented technique with the principle of operation of the chainsaw, it should be noted that the circulation is more accurate. More powerful equipment is designed for coarse sawing. With a circular saw, you can make neat cuts.

Reviews of experts about saws for wood

Circular saws for wood, the price of which is slightly lower than that of foreign counterparts, are produced by domestic manufacturers. For example, the Russian company “Interskol” produces a wide range of models of circular saw blades for wood.

Saw blades

Saw blades differ in different technical parameters. Discs are usually divided into types – for wood and similar materials, for metal.

Wood saw blades have tines inclined in the direction of travel. The more parts there are, the more accurate and accurate the cutting itself will be. Otherwise, the cut will be rough and torn..

A hand-held electric circular saw for wood, which will be used to cut fiberboard, boards, will require a type of knife with frequent teeth (about 100 pcs.). For cutting wood with many knots, a reinforced blade with 24 cutting edges should be selected..

Knife markings consist of two numbers. The first characterizes its diameter, and the second characterizes the diameter of the landing rod. Discs with a lower value than provided by the saw should not be installed on the equipment. Otherwise, there will be a space between the part and the casing where a hand can accidentally get into..

Types of equipment by functionality

There are several main types of circular saws..

Mini-circular saw is the first type of the presented tool. This is a portable equipment equipped with an electric motor. It is a handy tool for small and medium-sized jobs.

The fixed type circular hand saw for wood has a support. The saw is located on it. Unlike a mini circular saw, the engine of such equipment is located under the support and is started from a stationary network using a cord.

The third type of tool is represented by accumulator circulators. This is a fairly common type of equipment..

Another variation is the miter saw. It has a simple design with a handle with a start button, an operating unit and a saw blade..

Equipment parameters

One of the main parameters that you should pay attention to when choosing an electric type hand-held circular saw for wood is the number of revolutions. It would be more correct to choose equipment with the ability to control this indicator. This function will allow you to produce a better cut with an optimal level of load on the equipment..

Circular circular saws must have the protective functions of the electronics. This will help protect both the equipment and the operator in case of emergency situations at work. A blocking of accidental launch must be present.

It will not be superfluous to evaluate the appearance of the equipment upon purchase. It is very convenient to use an additional handle. The material of the product itself must be strong, capable of withstanding loads and mechanical stress.

Depending on the price, circular saws for wood are distinguished by the cleanliness of the assembly. Balance should be comfortable and the handles should not slip. This will allow you to firmly hold the technique in your hands..

Device

The constituent elements of a tool such as a circular saw for wood deserve consideration. Experts advise how to choose the most optimal model.

The engine power determines the performance of the entire mechanism. The higher it is, the thicker the boards can be cut with this equipment. The diameter of the knives used for tools such as circular saws for wood depends on the power. Their price directly depends on this indicator..

The weight of the circulator will also be higher with more equipment power. Therefore, before making the choice of a circular saw, it is necessary to determine the amount of work to be done. It is not worth overpaying for more power that will not be used.

Types depending on power

Three types are distinguished depending on the power:

The circulating saw motor has a power of 800 to 1200 watts. The thickness of the cut with this tool will be about 45 mm. Discs with a diameter of up to 160 mm are suitable for them. These are the cheapest types of equipment presented. Most often used at home.
The tool is equipped with an electric motor of an average power of about 1800 W. Its cutting depth reaches 60 mm. This is a semi-professional circular saw. 190-200 mm reaches the diameter of her knives.
The most productive type of tool, the motor of which has a power of more than 2000 watts. Discs of such circular saws are used from 190 to 350 mm in diameter. Most often, the tool is attached to a workbench. These are the most expensive professional, powerful saws.

Details of

The electric circular saw for wood involves cutting both in a flat plane and at an angle. For this, support plates and pins are used. An eccentric system is attached to them. The pin allows you to hold the equipment at an angle of usually 45. There are models that allow you to set the slope to 60. The tilt is made only to the right side. The left is usually the engine.

It is possible to set the level of immersion of the saw in the material. The mechanism fixes the equipment on a fixed axis. It is located in front of the support.

One of the most popular devices is the protective cover. Above, the protection is mobile, and below. fixed. Sawdust can be removed from the latter with a vacuum cleaner..

The wire must be protected by strong rubber insulation. Use batteries only when necessary, such as equipment such as mini circular saws..

Initially, the teeth are bred using a special tool. Sharpening a circular saw for wood is carried out initially from the back surface of the teeth, and then the front row is processed.

The beginning of the work to be performed must be marked with a marker. Each tooth should be sharpened the same number of times and with the same effort as the first tooth..

After the performed manipulations, the disc must be checked. A trial cut is in progress. If there is extraneous noise, uneven feed of the bar, this is a sign of non-uniformity of the teeth in height. This can be verified by holding the marker up to the cutting surface. After turning the knife, you need to inspect it and identify irregularities in sharpening.

The circular saw is successfully used not only in the industrial field, but also at home, when you need to make an accurate and fast cut of the product. A circular saw is something transitional between a jigsaw and a more advanced saw. Today we will look at the features of circular saws for wood, and how to choose the right one..

Circular saw for wood: design features. Standard circular saws and plunge saws. Mains and battery models

A hand-held electric circular saw for wood is a tool without which almost any joinery or carpentry task will become, if not impossible, then certainly quite difficult. At the same time, there are a lot of high-quality varieties of such devices, therefore, before buying a master (especially a beginner), it is advisable to learn as much as possible about their design.

In our article we will tell you what to look for when choosing a circular saw for wood, as well as give a number of tips for maintaining such tools..

Saw blades

Circular saws for wood are equipped with saw blades that differ in diameter, bore size and thickness. All data is indicated on the disk itself. Saw blades are classified into carbide and solid. The disadvantage of monolithic ones is that they quickly lose their sharpness, but they can self-sharpen. The advantages include affordable cost.

How to Choose a Circular Saw | Ask This Old House

Carbide wheels are more durable and are among the most common. When choosing a blade, you need to pay attention to the shape of the teeth, which affects the quality and speed of cutting. If you need to do a quick roughing job, choose a flat straight tooth. For a longitudinal cut, a disc with a small number of teeth and a positive slope is ideal. Cross-cutting is best done with a disc with a large number of teeth..

Work with aluminum, chipboard or laminate will be of high quality if you choose trapezoidal teeth. This will provide a good cutoff frequency and help avoid splitting the material..

An important feature is the thickness of the cutting disc. A thin saw uses much less energy and reduces waste. However, this material is prone to deformation and is not suitable for frequent and difficult work..

Now you know how to choose circular saw blades for wood and what criteria to pay attention to when choosing.

How to choose a hand saw for wood

When choosing a hand-held circular saw, first of all, you need to pay attention to the engine power and the speed of revolutions, which ranges from 1800 to 5000 revolutions per minute. For simple tasks, a model with low to medium engine power will work from time to time, but a more powerful model will be required for continuous work with a large cutting depth. The next thing to pay attention to. this is the diameter of the disc, the number and shape of the teeth, which are selected individually, for certain types of sawing. At the same time, you need to know that for each manufacturer, the ratio of the size and seat of the blade may differ, this characteristic is usually indicated on the saw body.

A good hand saw for wood is equipped with a special safety mechanism (protection against accidental activation), without pressing which the circular saw motor will not start. After completing the work, the protection button should return to its original position, automatically stopping the rotation of the disc.

Some models of circular saws are equipped with a mount designed for installing the tool on a workbench or bed, which allows them to be operated as a machine.

Before buying a tool, make sure that it meets your requirements and is suitable for performing the work according to the planned plans, and also has all the necessary documents that guarantee the quality of the product. And remember, the best hand saw combines safety, reliability and ease of use..

Circular hand saw

Until a few decades ago, woodwork was mainly carried out using a tool familiar to everyone. hacksaws, but those days have sunk into oblivion, and now few use this method of sawing. For coarser work that does not require precision, for example, to cut round timber, a chainsaw is used, and to perform a task requiring maximum precision, a circular saw is used. This type of power tool is right-hand and one where the motor is on the left. It is designed for sawing timber, chipboards and plywood..

Like all power tools, hand-held circular saws are divided into three types: household. with low power (500-1000 kW), professional. with a medium power motor (in the range from 900 to 1600 kW), industrial. with the most powerful engine type (over 1600 kW). The power of the engine determines the capabilities of the saw, such as the cutting depth, the size of the saw material, and labor productivity. The saw motor is installed on the saw blade, by setting it to the desired position, you can perform work at an angle of ninety or forty-five degrees, and using a specially provided mechanism, the cutting depth changes.

Performance depends on power, speed characteristics and type of disc. All discs differ in the material from which they are made, in the diameter, shape of the teeth and their number. To quickly complete the task, discs with a small number of large teeth are selected. For more precise work or for the final stage, saws with a large number of fine teeth are used, which pass much more accurately into the material being processed. When working with a circular saw, pay attention to the degree of contamination of the blade with resin and sawdust. Timely regular cleaning will significantly extend its life.

Saw blades

As standard when purchasing a saw, it will most likely be equipped with a standard all-purpose wood saw..

In addition, there are several other types of discs:

discs for wood
for a rough cut;
for finishing;
special discs for chipboard and laminated panels;
special discs for PVC panels and sheet aluminum;
multi-rip discs;
scoring with carbide taps.

Types depending on power

Depending on the diameter of the saw blade, the power of the saw motor is also calculated. Conventionally, today models are divided into the following classes:

low power up to 800 W;
average power from 800 to 1200 W;
high power more than 1200 W.

This classification allows not only to select the required saw blade, but also to ensure the correct operation of the equipment – for a small depth of cut, for some types of materials, especially plastic, saws with a small number of revolutions or models equipped with a speed controller are required.

Manufacturers

Sharpening discs

Sharpening of discs, as a rule, is carried out on special equipment designed for sharpening circular saws, at which the angle of inclination of sharpening is maintained, and standard parameters of the teeth are formed.

Carbide tipped saws are sharpened with special diamond grinding discs

Ordinary discs can, in principle, be sharpened with an ordinary file, but at the same time, the quality will be very doubtful.

Types of equipment by functionality

Considering a hand saw as a versatile tool, you need to understand that the base plate plays the greatest role in the functionality of this type of tool..

For almost all types of saw models, today the following functions are inherent in the basic configuration:

saw cutting depth adjustment;
saw tilt angle adjustment.

These basic parameters are largely similar for all types of both household items and heavy professional models, but here it should be borne in mind that:

adjusting the cutting depth requires rigid fixation, and if the engine and saw are raised high above the surface of the plate, vibration occurs, which requires great efforts when holding the tool;
the ability to cut at an angle in professional models is implemented in a more accurate scale of degrees, with a more rigid fixation of the selected parameter;
the functionality of professional models is also expressed in the possibility of stationary attachment of the saw to any surface, with obtaining a full-fledged circular saw.
choosing equipment of an approximate class and close in technical parameters, preference should be given to models with a platform made of aluminum casting, such platforms are more stable and less susceptible to deformation;
the next selection criterion should be the nodes for fixing the position of the saw, the quality of the work results will largely depend on the quality of these nodes.

Device

The circular assembly saw includes the following components:

base;
engine body;
fixed protective casing;
saw blade;
protective movable casing;
adjusting devices;
handle with power and lock keys;
persistent front handle;
parallel guide;

Details of

Without exaggeration, a very important place in any circular saw is the attachment point for the circular saw to the shaft. Various fastening options implemented in various models mainly boil down to the use of various kinds of nuts – both the usual hexagonal shape and special ones, under a special wrench.

In the process of replacing the disc, a uniquely positive part will be the shaft stopper, which is used to fix the shaft while clamping the nut, similar to that found in angle grinders..

Overview of the most popular models

How to choose a reliable circular saw for wood for home and garden – an overview of all parameters and tips

Anyone who constantly deals with cutting wood knows perfectly well that the choice of tool depends not least of all on the dimensions of the workpiece that has to be cut. If we are talking about massive logs, then a complete replacement for a chainsaw cannot be found. When working with slabs, panels and plywood, the jigsaw becomes an indispensable assistant. But what if in practice there are different samples of wood?

In this regard, a circular saw for wood is truly universal, and in most cases it is able to cope with the work for which the above tools are intended. The main thing is to choose the optimal circular saw model. How to evaluate all its capabilities and what to clarify – the topic of the article.

People who have to deal with such a tool for the first time often confuse a circular saw (the more common name in everyday life is a circular saw) and a miter saw. These are slightly different tools, although they are designed for sawing wood and a number of other materials with a relatively soft structure. Learn more about the miter saw here.

Skil 5740 CA series

The power is slightly higher – 0.7 kW at 4,300 rpm. The same blades are suitable for such a saw as for “Bosch”. According to sales statistics, one of the most purchased household models.

Technical support of the product

Many people forget about this, although you always need to prepare for the worst. After all, everything ever fails, and a circular saw is no exception. What is necessary to clarify?

Location (address, contact numbers) of the nearest service center that deals, among other things, with such models. Is he the official representative of the saw blade manufacturer? Otherwise, the repair will be delayed, and its cost will be tangible. The reason is that firms that have no connection with the manufacturer buy spare parts on the market or via the Internet, which affects the final price of the part. In addition, there will be difficulties with the guarantee. On the spot, no one will diagnose and eliminate the malfunction. You will have to send the product and wait for the result, sometimes for several months.
Is it possible to find accessories for a circular saw of this model in this locality in order to repair it yourself (in the post-warranty period), or will there also be problems with this. That is, to assess its maintainability.

All such nuances should be clarified immediately, even before buying. Otherwise, there is a risk of being left alone with your problem in the future..

Platform execution

“Stamping” is less reliable, which is why such circular saws are cheaper. Cast platforms – almost all models of professional tools and some of the household class.

An additional plus is the presence of markings along the edge of the slab. This greatly simplifies the cutting of a tree when the utmost precision is important..

Disc retention mechanism

The speed of changing the working tool depends on its performance. In some cheaper models, you will have to use a special key to remove (reinstall) it. For domestic use it is not essential, but for a professional it is an additional waste of time.

Bosch PKS 40 series

A power of 0.6 kW is quite enough for most household jobs. The 130 mm disc allows you to make a guaranteed cut in 40 – 45. Rotation speed (rpm) – 4 500. Therefore, the cut is quite clean. This tool is hand-held, mobile, and with a weight of 2.2 kg allows you to work in almost any position.

Saw blade selection criteria

We will consider all the positions by which a circular saw should be judged on wood, and we will help you make the right choice of tool.

Models of self-powered circular saws (from batteries) are also on sale, but they have a limited scope and differ little in efficiency from a high-quality electric / jigsaw. Therefore, it is hardly worth dwelling on them..
