First of all, It’s necessary to Find out that circular saw is suitable for a particular job, as by the design of this tool you will find:

• Stationary – really a machine, which is a saw mounted on a frame. Requires free space in the workshop, and on occasion another room. Made such a circular saw to get permanent processing of timber, and in massive volumes.
• Table – the prior version in miniature, installed on another workbench or table, can also be used for sawing a large volume of timber, for example, during the building of the tub.
• Manual – a portable tool, designed for processing workpieces in distinct planes. Here is the most usual kind of circular saw, but the strongest of this clarified. After working, it needs periodic remainder, and can be utilized for sawing small quantities of substance.

Hand-held tool is more versatile than stationary variants. It costs much cheaper, but under certain conditions is able to deal with the same actions, though with less efficiency. When picking it, you ought to be guided by the standards below.

Power

According to the type of power source, circular electric saws are divided into 2 classes:

• Networked – they work out of a domestic electric system of 220 V. If we discuss professional machines, then they need a lineup of 380 V. The drawback of this connection option – the requirement to have an energy grid in the area of work, as well as some inconvenience of operation due to the cable.
• Vacuum – operate in standalone mode, even require the presence of a socket, but to charge the battery, so their radius of operation is not constrained by anything. Based on battery capacity, they can work on a single charge not more than 50 minutes.

Submersible saws – come in stationary and handheld versions. Their difference is in the fact that the saw blade at the initial position is within the workpiece, able to descend into the centre. This enables you to begin cutting not with the edge of the material, cut through holes.

Metal round saws are powerful models that are equipped with more durable or abrasive discs. Capable of cutting sheet steel, pipes, profiles. Some of them manage wood equally well.

The width of the disc directly is dependent on the power of the saw’s electrical engine. The more powerful the tool, the larger the disc it is able to rotate, the more secure the spinning frequency of the latter, the longer the length of constant operation, the less probable the wedge. Additionally, powerful saws allow you to process heavier material, but in addition they are thicker. Therefore, for example, models at 2 kW on average weigh 7 kg, while 1.2 kilowatt – about 4 kg.

According to the power gears could be split as follows:

The bigger the width of the disk, the stronger the electric motor has to be, the heavier the workpieces the saw can work with. Seating diameter is another parameter that determines if a specific disc will match the selected saw. The most typical standards here are 20 and 30 mm.

At greater rates, less torque is necessary for sawing, meaning dense material is simpler to deal with. Remember that with higher RPM the warmth of this material at the area of touch with the saw gains, the same plastic or laminate requires less RPM. Ideally, it’s better to choose a saw with flexible speed.
