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.
