First of all, it is necessary to determine that circular saw is Acceptable for a particular job, as by the design of the tool you will find:

  • Stationary – really a system, which can be a saw mounted on a framework. Requires free space in the workshop, and at times a separate room. Designed such a circular saw to get permanent processing of lumber, and in huge volumes.
  • Table – the previous version in mini, installed on a separate workbench or table, can also be employed for sawing a large volume of timber, as an example, during the building of the tub.
  • Guide – a portable device, designed for processing workpieces in different planes. This is the most typical kind of circular saw, however the strongest of the clarified. When functioning, it takes periodic remainder, and is used for sawing small quantities of substance.

Hand-held instrument is much more versatile than stationary variants. It costs considerably more economical, but under specific conditions is able to cope with the very same tasks, even with less efficacy. When picking it, you ought to be guided by the standards below.


According to the type of power source, circular electrical saws are divided into two classes:

  • Networked – that they operate from a domestic electric system of 220 V. If we talk about professional machines, they need a line of 380 V. The drawback of the connection option – the need to have an electricity grid at the area of work, in addition to some inconvenience of operation due to the wire.
  • Cordless – work in standalone mode, additionally need the presence of a socket, but to control the battery, so their radius of operation is not confined by anything. Depending on battery capability, they could work on a single charge not more than 50 minutes.

The second option makes sense to purchase only if for any reason it’s not possible to utilize the mains viewed. Type of work

Submersible saws – come in stationary and handheld versions. Their difference is in how the saw blade in the initial place is over the workpiece, able to seep to its centre. This enables you to begin cutting with the edge of this material, cut through holes.

Metal circular saws are powerful models that are equipped with more durable or abrasive disks. Capable of cutting sheet steel, plumbing, profiles. Some of them handle wood equally well.

The diameter of the disc directly depends upon the ability of the saw’s electrical motor. The more powerful the tool, the bigger the disk it is in a position to rotate, the more stable the rotation frequency of the latter, the more the length of constant operation, the less likely the wedge. In addition, powerful saws permit you to process heavier substance, but they also are thicker. Thus, by way of instance, versions at two kW generally weigh 7 kg, while 1.2 kilowatt – about 4 kg.

According to the energy gears can be split as follows:

  • 0,8-1,2 kilowatt – the instrument of typical power, is able to deal with most household jobs.
  • More than 1,2 kilowatt – saws for professional use.
  • The larger the width of the disc, the stronger the electrical motor has to function, the heavier the workpieces the saw can use. Seating diameter is just another parameter that decides whether a particular disc will match the selected saw. The most usual criteria below are 20 and 30 mm.

    At higher speeds, less torque is needed for sawing, which means dense substance is easier to take care of. Bear in mind that using higher RPM the warmth of the substance in the area of touch with the saw increases, the identical plastic or laminate needs less RPM. Ideally, it is better to pick a saw with adjustable speed.
