First of all, it is necessary to Find out that circular saw is suitable for a particular job, depending on the design of the tool you will find:

• Stationary – actually a machine, which can be a saw mounted onto a frame. Requires free space from the workshop, and occasionally another room. Made such a round saw to get permanent processing of timber, and in massive volumes.
• Table – the previous version in miniature, installed on a separate workbench or table, is also used for sawing a huge volume of timber, by way of instance, during the construction of the bath.
• Guide – a mobile application, intended for processing workpieces in different planes. Here is the most frequent kind of round saw, however the least powerful of the described. After working, it requires periodic break, and is used for sawing small quantities of substance.

Hand-held instrument is much more versatile than stationary variants. It costs much more economical, but under specific conditions is able to deal with the exact tasks, though with less efficacy. When picking it, you ought to be guided by the criteria below.

Power

According to the type of energy supply, circular electric saws are divided into two classes:

• Networked – they operate out of a domestic electric network of 220 V. If we talk about professional machines, they need a lineup of 380 V. The drawback of the connection alternative – the requirement to have a power grid at the area of work, in addition to some inconvenience of operation due to the cable.
• Vacuum – operate in standalone mode, also require the presence of a socket, but to charge the battery, therefore their radius of performance isn’t restricted by anything. Depending on battery capacity, they can work on a single charge not over 50 minutes.

The second choice is reasonable to buy only if for some reason it is impossible to utilize the mains observed. Form of work

Standard circular gears are designed for sawing wooden workpieces at different angles, however there are moyakovka.ru also special versions of this tool:

Submersible saws – come in handheld and stationary versions. Their difference is in how the saw blade at the first place is over the workpiece, able to seep to its center. This enables you to start cutting off not with the edge of the material, cut through holes.

Metal circular 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 both well.

The width of the disk directly is dependent upon the ability of the saw’s electric engine. The more powerful the instrument, the larger the disc it’s able to rotate, the more secure the rotation frequency of the latter, the more the length of constant operation, the less likely the wedge. Furthermore, strong generators allow you to process heavier substance, but in addition they are heavier. Thus, by way of instance, versions at two kW generally weigh 7 kg, whereas 1.2 kW – approximately 4 kg.

According to the power gears could be broken as follows:

• As much as 0.8 kW – low-powered instrument for working with small workpieces.
• 0,8-1,2 kW – the instrument of typical power, can cope with many household tasks.
• Over 1,2 kW – gears for professional usage.

How to Pick a circular saw: professional tips

The bigger the width of the disc, the more powerful the electric motor must be, the thicker the workpieces the saw can use. Seating diameter is just another parameter that decides whether a specific disc will fit the chosen saw.

At greater speeds, less torque is required for sawing, which means dense substance is easier to deal with. Bear in mind that using higher RPM the warmth of the substance at the area of touch with the saw gains, the exact same laminate or plastic requires less RPM. Ideally, it’s much better to choose a saw with flexible rate.
