3M Scotch-Brite Roloc Bristle Discs with Ceramic Abrasive Grain are a fast-running abrasive disc that combines superior cutting action with the Roloc quick change attachment system to help you efficiently clean, strip, deburr, blend, finish, polish, scratch, and remove rust and coatings without damaging the base material. Under normal use the molded, abrasive filled bristles remain safely in place and can achieve the desired finish using light pressure while working more effectively than wire discs and wheels. The bristle spacing makes them ideal for removing thick coatings, gaskets and other high loading materials.
