Cubitron™ II 7100032406 Abrasive Cut-Off Wheel, 3 in Dia Wheel x 0.04 in THK Wheel, 3/8 in Center Hole, Aluminum Oxide Abrasive

3M™ Cubitron™ II abrasive discs, cutoff wheels and file belts have raised the bar for high performing abrasives. Cubitron™ abrasives feature our precision shaped Grain (PSG) technology, which allows our engineers to control the geometry of the abrasive grain for a truly fast, efficient cut. Instead of simply crushing the abrasive into particles, 3M™ uses micro replication to uniformly size ceramic grains and precisely shape them into triangular structures essentially, sharp peaks that slice, not plow, through paint and metal. These grains are electrostatically oriented on the abrasive surface for the most efficient cut and even wear. What's more, PSG fractures during use to maintain sharp abrasive edges. The result: Cubitron™ II cuts 30% faster and lasts 2x longer than conventional ceramic abrasives.
