Deburring tools remove rough edges, unwanted projections, and surface imperfections from workpieces. Carbide burs have sharp cutting edges that cut away material to smooth, shape, and grind surfaces and edges. Mounted points are small, bonded abrasives for grinding, polishing, roughing, or removing material. They're also used for cleaning and detailing metal tools or finishing in tight spaces, such as between machine gears. Hand deburring tools have sharp blades that remove rough edges around openings or along corners.
