The Best Way to Select a circular saw: professional Hints

First of all, it is necessary to determine which circular saw is Acceptable for a particular job, as by the design of the tool there are:

  • Stationary – actually a system, which can be a saw mounted onto a frame. Requires free space in the workshop, and sometimes a separate room. Made such a round saw for permanent processing of timber, and in huge volumes.
  • Table – the previous version in mini, installed on another workbench or desk, is also used for sawing a huge volume of wood, by way of instance, during the building of the bath.
  • Guide – a mobile device, created for processing workpieces in different planes. Here is the most common kind of round saw, but the strongest of the clarified. After working, it requires periodic remainder, and is utilized for sawing small amounts of material.

Hand-held tool is much more versatile than stationary variants. It costs considerably more economical, but under specific conditions is able to deal with the very same tasks, though with less efficacy. When choosing it, you should be guided by the criteria below.

Power

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

  • Networked – that they work from a domestic electric network of 220 V. If we discuss professional machines, then they require a lineup of 380 V. The drawback of the connection alternative – the necessity to have an electricity grid at the area of work, in addition to a hassle of operation because of the cable.
  • Vacuum – operate in standalone mode, even require the existence of a socket, but to charge the battery, therefore their radius of operation isn’t constrained by anything. Based on battery capability, they could work on a single charge not over 50 minutes.

The second option makes sense to buy only if for some reason it is impossible to utilize the mains viewed. Form of work

Submersible saws come in stationary and handheld versions. Their difference lies in how the saw blade at the first position is within the workpiece, capable to descend into its own centre. This allows you to start cutting with the border of this substance, cut through holes.

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

The width of the disc directly is dependent upon the ability of the saw’s electric engine. The more powerful the tool, the bigger the disc it’s in a position to rotate, the more stable the rotation frequency of the latter, the longer the duration of constant operation, the less likely the wedge. Moreover, strong generators permit you to process thicker material, but in addition they are heavier. So, as an instance, versions at 2 kW generally weigh 7 kg, while 1.2 kW – about 4 kg.

According to the energy saws could be split as follows:

  • Up to 0.8 kilowatt – low-powered tool for working with small workpieces.
  • moyakovka.ru

  • 0,8-1,2 kilowatt – the tool of ordinary power, can cope with many household tasks.
  • Over 1,2 kilowatt – generators for professional usage.

How to Select a circular saw: professional tips

The bigger the diameter of the disk, the stronger the electrical motor has to function, the thicker the workpieces the saw may work with. Seating diameter is another parameter that decides if a particular disc will match the selected saw. The most typical standards here are 20 and 30 mm.

At greater speeds, less torque is needed for sawing, meaning dense substance is simpler to deal with. Remember that with higher RPM the temperature of this substance at the area of touch with the saw raises, the same laminate or plastic needs less RPM. Ideally, it’s far better to choose a saw with adjustable rate.
