Angle grinders are primarily used to polish and grind metal surfaces. If you need to cut away excess or deburr surfaces, you’ll need a sturdy and powerful polisher you can rely on. Most modern grinders are electrically powered. The smaller options tend to deliver higher RPMs, which is great if accuracy is your priority. For deeper cuts, however, you’ll probably need a larger angle grinder with a large blade. You’ll find quality products from leading brands here, including Hikoki, Makita and Bosch.
