Scotch-Brite™ Radial Bristle Disc, using proprietary 3M™ Ceramic Abrasive Grain and molded, flexible bristles, provides more surface contact than wire brushes and maintains abrasive property throughout the life of the disc. Our fast-running disc removes paint, stains, adhesives, weld burns, rust, heavy oxides, and surface contaminants from large areas. The Scotch-Brite™ Radial Bristle Disc Thin Bristle SB30129 makes tough jobs easier and can help you achieve a burr-free, paintable finish in fewer steps without damaging the base material. The non-woven, open web, durable construction is designed to resist loading and greatly increase the life of the disc. The Scotch-Brite™ Radial Bristle Disc Thin Bristle SB30129 fits most portable hand tools and small bench motors. For additional abrasive needs combine multiple discs to form a brush.
