3M's Aluminum Oxide Abrasives are made of high-grade mineral and a bonding system that reduces shelling of the mineral. These economical abrasives are excellent for fast clean-up and pre-polishing work.
Use the Sanding Bands with 3/32" (2.35mm) and 1/8" shank rubber drum mandrels. To install, slip band onto rubber drum with screw loose. When band is in position, tighten the screw, which expands the rubber drum, for a secure hold.
