HOW TO CHOOSE A CIRCULAR SAW

Published : 09/20/2018 12:19:23

Circular saws appeared for the first time in the late 18th century and were mainly used in sawmills. Nowadays, the circular saw is a very common power tool, used by a lot of professional workers: it uses a  rotary motion to cut different materials, thanks to a serrated blade or an abrasive disc. But what is a circular saw used for? It is a power tool specific for cutting many materials, such as plastic, wood, metal and more; you simply need to choose the correct circular saw blade according to the material you need to work on. If you are wondering how much a circular saw is, it depends on the model you need: you can find entry level saws at €100.00 as well as professional circular saws priced over €600.00.

Which circular saw should you choose?

First of all, always remember that a good professional circular saw should have enough power to cut everything, from hardwood to plastic, without abruptly stopping. This is not just essential for the success of the work you are doing, but also for your security.

All kinds of circular saws have the same standard components: the blade guard, designed to cover the blade when the saw is not in use; the bevel adjustment, useful when you need to make beveling jobs; the foot plate (or shoe), designed to steady the saw against the object on which you are working; and the depth adjustment, to work on objects with different thicknesses.

There are basically two circular saw designs to choose from:

  • Sidewinder (or inline): the traditional circular saw, with the engine on the same axis of the blade. Sidewinder saws are compact and lightweight, perfect for most applications.
  • Worm drive: the engine is on the right angle of the blade and uses gears to increase the input strength on the blade. Worm drive saws are bigger than inline ones, and are perfect for heavy-duty applications.

Which circular saw you should choose?

There are also two types of power supply to choose from:

  • Cordless saws: perfect to be used in a confined space, where you don’t have the option to use extension cords. They are ideal to cut wood, but not suggested to work on harder materials, because they don’t offer extra power and are slow to recharge.
  • Corded saws: ideal for cutting tough materials like steel and masonry, but also for continuous woodcutting. They don’t depend on batteries, so they offer you non-stop power without interruptions. Note: if you can’t work near an electric socket, remember to buy a suitable extension cord.

At this point, all you have to do is to compare the features of the circular saws you have selected. First of all, take a look at the cutting power: you can find it in amps on corded saws and in volts on cordless saws, and a higher level of these indicators means more cutting power. Then, it’s time to think about the blade capacity, which determines the maximum cutting depth of the saw: the larger the blade, the deeper the cut. Just remember that circular saws with larger blades also weigh more and are harder to control while in use. Now, you should take a look at the bevel capacity, which indicates the maximum saw bevel cutting, and finally check if the circular saw you want to buy has laser guides, these are useful to improve cutting accuracy.
