How to use a circular saw properly

The circular saw is the ideal tool for cutting wood over long lengths. The circular saw is the solution for quickly and efficiently cutting panels in solid wood, plywood, melamine, chipboard … It is a powerful power tool, more than 800 watts, which means beginners must be careful.

The principle of cutting is simple, a disc is rotated in a counterclockwise direction. The cutting is done by sharp teeth arranged around the circular blade. Like many top rated table saws, it is made to cut wood in thicknesses varying from 5 to 50 mm. It can cut larger thicknesses provided the motor is strong enough and the blade allows it.

Unlike the jigsaw, the circular saw is not suitable for cutting metal, glass or tiles.

Step 1: Choose a circular saw blade.

circ sawThere are mainly two types of blades:

-HSS high-speed steel blades

-Tungsten carbide blades.

The HSS blades are rather dedicated to the cutting of solid wood. Instead, we recommend that you use a stronger tungsten carbide saw that can cut both solid wood and plywood or melamine panels.

The most important differentiating criteria for comparing cutting discs are the number of teeth and the fineness of the tips: the finer the teeth and the smaller the pitch (many teeth), the more precise your cut.

To make sure that the blade fits perfectly into your machine, check the instructions for the diameter of the tool shaft and the maximum diameter of the discs compatible with your circular saw. With this information, you will be sure to choose a perfect blade.

Step 2: adjustment.

A circular saw offers two settings: height and angle of cut.

In order to obtain the most precise and cleanest possible cut, it is recommended to adjust the height so that the blade is greater than the thickness of the piece by 8 to 10 mm. A clamping screw on the rear of the tool allows you to make this adjustment. Place the blade at the edge of the cutting board to pick the right depth.

Step 3: General tips

You must always saw in good conditions to be able to get a clean cut

Always use a guide to ensure a straight cut. If the supplied guide is not large enough, use a clamp with guides. When carrying out measurements on the panel or workpiece, consider the thickness of the blade.

A circular saw must be well taken care of in order to limit the vibrations and possible deviations of the blade. Remember to never force the machine forward, you must allow it time to cut the material.

Keep the switch engaged until the end of the cut and until the protector returns to its place.
