This 3M 747D Cartridge Roll is ideal for metal finishing in small hard to reach areas like corners or inside pipes. They are made from a blend of aluminum oxide and 3M ceramic grain on a strong cotton backing around a solid mandrel core. The ceramic aluminium oxide blended mineral breaks down to reveal sharp cutting edges, and the anti-friction grinding aid helps to reduce grinding temperatures to allow the abrasive to run smooth.
