Be safe when you use your cut-off circular saw.

Diamond Cutting Blade cutting kerb stones
A circular saw or cut-off saw can be used for a variety of operations in the construction trade, namely cutting steel, concrete, bricks, blocks or asphalt. It is important you select the right blade for the job you want to carry out.
A cut-off saw’s diamond cutting wheel/blade rotates at extremely high speeds. The blade of the saw is a very dangerous object due to its rotating speed and unguarded cutting surface.
Below are a few safety tips for cut-off saw users:
