A bench grinder or pedestal grinder is a machine used to drive an abrasive wheel (or wheels).
Depending on the grade of the grinding wheel it may be used for sharpening cutting tools such as lathe tools or drill bits. Alternatively it may be used to roughly shape metal prior to welding or fitting.
Wire brush or buffing wheels are often mounted in place of the grinding wheels and are used to clean or polish work-pieces.
