Abrasives remove material from a work-piece. Sanding discs, sanding belts, sandpaper, deburring tools, and other industrial abrasive products eliminate rough edges, nicks, and notches from metal work-pieces or shave off layers of wood. Grinding and cut-off wheels cut, grind, sand, or finish metal, glass, wood, brick, or concrete surfaces. Abrasive-blasting equipment delivers abrasives at high pressures to clean and finish surfaces. Polishing and buffing abrasives leave a smooth, lustrous finish on a work-piece for an attractive appearance. Abrasive accessories such as sharpening stones and abrasive dressing products help keep tools ready for the next job.
