The 3M 05810 Scotch-Brite Clean & Strip XT Pro Disc in purple is an extra coarse silicon carbide abrasive disc designed for aggressive cleaning and stripping applications. It effectively removes rust, paint, mill scale, coatings, and adhesives from metal surfaces without significantly altering the base material. Featuring high-strength fibers, this disc resists chunking and loading, offers high conformability for a larger contact area, and provides low vibration and spark for a safer, longer-lasting performance. Ideal for pre and post-weld cleaning and general surface preparation.
