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

Actually circular saw design has not changed much since inception.Of course, the tool has become more ergonomic and powerful, weight decreased, but the principal changes have occurred only with the saw blade.There are currently so many different saw blades, designed to work on different materials such as wood and wood products, aluminum and alloys, laminates, etc.

main units of circular saws:

- electric motor;.

- gear housing;

- a protective casing;

- platform and guide.

Housing circular saws are generally 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 of drinking most of the manufacturers are paying particular attention to ventilation and cooling systems, as well as removal of the chips.It is, first and foremost, to protect the workers 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, a circular saw MAKITA 5017 RKB with an engine capacity of 1,400 kW, and the saw blade diametrom190 mmimeet in its design a container to collect the shavings, which allows to remove more than 90% of the chips that are inevitably formed when using a chain saw.With no large volumes of work is practical, but if you work a lot, circular saw Makita 5017 RKB creates some discomfort in the purification of the collection of sawdust.

Some manufacturers in order to make the work with the tool more comfortable, resorted to highly original solutions.For example, a circular saw Worx WT431KE from WORX company (the diameter of the saw diska185 mm engine power 1.5 kW) has a "revolving handle", which can change its angle of inclination of 60 degrees.This is a very useful innovation, since the operator can operate the saw as it is convenient, depending on individual anatomy.This engineering solution developed by WORX and realized only in the tools of the manufacturer.

All modern circular saws are equipped with collector motor power from 500 to 2500 watts.Engine power affects the parameters such as depth of cut and the number of revolutions of the saw blade.More 10 years ago, circular saws have an average of 3 000 rev. / Min.For example, the model of the circular (circular) saw MAKITA 5143R power to 2.2 W (diameter diska355 mm) are not descended from the market for the past 10 years, has 2,700. / Min.

Modern models have already drank up to 5000 rpm, for example, circular (circular) saw BOSCH GKS 85 (power of 2.2 kW, the diameter of diska235 mm).

Special mention deserves the new version of this tool - Cordless Circular Saw.For example, a large range of cordless tools, among which different types of batteries equipped with circular saws, developed by BOSCH.One of the most interesting novelties - Circular Saw BOSCH GKS 36 V-LI Professional, working on high-quality lithium-ion batteries.The tool is equipped with disc diametrom165 mm (4000 rpm. / Min) and weighs vsego4.8 kg.

batteries can be equipped with not only the professional level tools, but also a number of household tools.Unlike equipment such as drills, professional drills, circular saws, angle grinders, are not equipped with a lock release button, which allowed to consolidate it in the switching position.This is due to the high safety requirements.

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

before selecting disc (circular) saw, particular importance should be given to the design of its platform.For home use can come from drinking stamped platform - as a rule, these saws have a lower cost - but saw, equipped with aluminum die-cast platform for professional users a better experience.Such a platform is more resistant to deformation and therefore saw would be more accurate to use.Many manufacturers have applied to the blade platform of a special layout, which can be used to more accurately perform the sawing material.

In addition, you must pay attention to the possibility of replacing blade .If the saw blade spindle lock missing, the replacement drive is only possible 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 their drink, but be aware that they are suitable only for instruments of the same manufacturer.

Special attention should be paid to saw wheels.Today saw blades are available for virtually any material.High Quality CDs due tipped tungsten carbide, geometry and frequency of teeth on the disc.There are wheels on wood, is - according to the laminate, after which the work surface of the material does not require treatment.Using modern saw blades, can not be afraid of what saw, hit a left in the board nail breaks.

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