3M’s Ceramic Purple Abrasives are excellent for sanding and finishing wood, metals, fiberglass, diestone, plastics, and other materials. 3M’s Cubitron ceramic aluminum oxide mineral sharpens itself with use. Once initial grinding wears the grain flat, it fractures along micro cracks creating new cutting edges. This process repeats itself throughout the entire grinding process. 
- 2 to 4 times longer abrasive life than traditional aluminum oxide bands and discs
- Faster stock removal with less heat and loading
- 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.
 *Optimum Operating Speeds are much lower (between 25%–50% of maximum speeds) and also depend on the type of workpiece.
