Featuring 3M Ceramic Abrasive Grain technology and moulded, flexible bristles, the Scotch-Brite™ Bristle Disc provides more surface contact than wire brushes and helps remove surface contaminants from large areas. This disc's abrasive blend continually self-sharpens to help the disc run fast and last longer for enduring performance. Use this disc to help remove paint, stains, adhesives, weld burns, rust, heavy oxides, and surface contaminants.Scotch-Brite Bristle Discs are engineered to last longer and provide more surface contact than wire brushes. 3M's Ceramic Abrasive Grain technology features a blend of aluminum oxide and ceramic abrasive grain that enhances the toughness and hardness of the grain and continually self-sharpens to maintain a high cut rate. Combined with non-woven nylon or synthetic fibres, these abrasives form an open-web material that runs cool resists loading.
