Ceramic Purple Sanding Bands from 3M. Use with mandrel A-SD145.
Made in USA. 10,000 RPM Max Speed.
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
Available in 80, 120, and 220 grit
Use Sanding Bands with 3/32″ (2.35mm), 1/8″ 1/4″ & 6mm shank rubber drum mandrels.
Use PSA Sanding Discs (pressure sensitive adhesive) on disc mandrels in 3/4″ 2″ and 3″ (19, 51, & 76mm) diameters.
*Optimum Operating Speeds are much lower (between 25%50% of maximum speeds) and also depend on the type of workpiece.
