Handy tips for using tools like the crowbar, broom, shovel, impact driver, (angle) grinder, reciprocating saw and grease gun.

POWER Tools

(Angle) Grinder

Grinder

This is a genuinely dangerous tool. A study of workplace injuries treated at two emergency departments in QLD, Australia found it had the highest injury rate of all power tools — and not just by a little: it was twice as high as the tool in second place. Plenty of sites will hand you one without proper instruction, so you really need to know the basics before you use it.

ℹ️ Note

A grinder is designed for grinding, not cutting. Still, because it's so handy, it gets used for cutting all the time.
