Bench Grinders Featues

A bench grinder is a very simple tool. The units are usually listed as 6-inch or 8-inch wheel models, and the 8-inch units are typically a bit more powerful, and subsequently more expensive. A 6-inch model will usually be powered by a 1/2 HP motor, where the 8-inch will be larger, likely 3/4 HP. Two very useful features to look for are a mounted work light, which will directly illuminate your work, and an adjustable rest, which functions much like the tool rest on a lathe. Strongly consider models which have both features. Many also include a clear, see-through spark guard, which will help keep any sparks from flying toward your face. A word of caution, though: such a guard does not replace safety goggles.
