Tool called Skilsaw - the prototype of the modern circular saw - was released into production in the mid 20-ies of the last century.

The design features a circular saw

As known, circular (circular) Saw - a hand-held power tools, designed for longitudinal and transverse cutting of wood, wood materials, plastic and soft non-ferrous metals. Work with the saw blade is characterized by high speed and precision, because this tool is literally irreplaceable in the performance of roofing works, the manufacture of furniture, laying floors and other woodwork. Saw, equipped with special discs, also applies when working on the cutting out of metal profiles, used in furniture design.

Actually circular saw design has not changed much since inception. Of course, tool has become more ergonomic and powerful, weight decreased, but the principal changes have occurred only saw blades. At present there are a lot of different saw blades, designed to work on a variety of materials, this, as tree and wood-based materials, aluminum and alloys, laminates, etc..

The main components of a circular saw:

  • Electrical engine;
  • gear housing;
  • protective shroud;
  • platform and guide.

Housing circular saw, usually, It is made of a durable heat-resistant plastic, at least - made of metal. Since working with the saw blade is often necessary to perform in dusty conditions, the development drank most of the manufacturers are paying particular attention to ventilation and cooling system, as well as the removal of chips. it is, Firstly, to protect the worker from dust, which has a negative effect on health. All modern circular saws can be connected to an industrial vacuum cleaner or a dust extraction system. For this purpose, special adapters. Some saws are equipped with stationary systems remove dust and shavings. for example, Circular Saw MAKITA 5017 RKB with the engine capacity 1.400 kW diametrom190 mmimeet saw blade in its design a container to collect sawdust, Allows you to delete more than 90% sawdust, that are inevitably formed when working with a saw. If no large volumes of work is practical, but if a lot of work, the circular saw Makita 5017 RKB creates some discomfort in cleaning sawdust collection.

Some manufacturers in order, to do the work with the tool more comfortable, resorted to a very original solutions. for example, Circular Saw Worx WT431KE from the company WORX (dyska185 mm diameter saw, engine power 1.5 kW,) equipped with a "revolving handle", which can change its angle of inclination to 60 degrees. This is a very useful innovation, since the operator is able to work as a saw, as it is convenient, depending on individual anatomical features. This engineering solution developed by WORX and realized only in the tools this manufacturer.

All modern power saws are equipped with the commutator motor of 500 to 2500 W. Engine power affects such parameters, the depth of cut and the number of revolutions of the saw blade. Still 10 years ago, circular saws had an average 3 000 vol. / min. for example, circular model (disk) Saw MAKITA 5143R power 2.2 to W (mm diameter diska355), not descended from the market during the 10 years old, It has 2700 vol. / min.

Modern models have already drank up 5000 revolutions, as, eg, circular (circular) Saw BOSCH GKS 85 (power 2.2 kW, mm diameter diska235).

Special mention deserves the new version of this tool - cordless circular saws. for example, a large range of cordless tools, among which is equipped with various types of batteries of circular saws, developed by BOSCH.

Batteries can be equipped with not only the professional level tools, but a number of household tools. In contrast to such equipment, like drills, professional drill, circular saws, angle grinders, not equipped with a lock release button, which would allow to fix it in the switching position. This is due to the high safety requirements.

Modern electric saws often have another interesting and useful innovation - laser pointer. Even if the sawdust zasyplyut marked-cutting line, then in the presence of a laser pointer it will not interfere in the work of.

Before you select a disk (circular) dust, particular importance should be given to its design platform. Saw with stamped platform may be suitable for everyday use - usually, these saws have a lower cost, - but for professional use may have a better drink, equipped with aluminum die-cast platform.

Many manufacturers have applied to the blade platform, mark, which can be used to more accurately perform sawing material.

Besides, you must pay attention to possibility of replacement of the saw blade. If the saw blade is no spindle lock, the replacement of the disc is possible only with the help of two keys, which is very difficult and takes a long time.

When you need to perform high-precision work, it is desirable to pay attention to the guide rail. All companies produce guide rails for its drinking, but it must be taken into account, that they are suitable only for instruments of the same manufacturer.

Special attention should be paid to saw blades. Today saw blades are available for almost all materials. High quality disc due tipped tungsten carbide, geometry and frequency of teeth on drive. There are wheels on wood, is - for laminate, after which the work material surface does not require processing. Using modern saw blades, you can not be afraid of, that saw, hit a left in the nail board, will break.


It should be noted, that the repair of the saw blade - a very expensive event. for example, the cost of replacing the anchor is almost equal to the cost of a new blade. The cause of wear on anchor slots can be such a thing, as the excessive pressure on the tool itself during operation, an error in the selection of the saw blade or damage or defect (no carbide solders, wrongly made sharpening).
