3M Cubitron

3M reinvented abrasives with 3M™ Cubitron™ II Products. The secret lies in the revolutionary precision-shaped ceramic grain technology pioneered by 3M. As the triangular shaped grain wears, it continuously fractures to form sharp points and edges that slice through metal, wear evenly and provide super-long life and consistency at any grinding pressure. This allows 3M™ Cubitron™ II belts, discs and bonded wheels to run cooler and keep on working—long after conventional abrasives have dulled, shelled, glazed over and been thrown out.
