Cubitron™ II Abrasive Technology

Technology: Precision-Shaped Abrasive Grain Changes the Game

With decades of experience in ceramic, microreplication and abrasive technology, 3M has literally reinvented abrasives with 3M™ Cubitron™ II Products. Starting with a patented, precision-shaped ceramic abrasive grain, 3M engineers found a way to electrostatically orient each triangular structure to maximise cutting potential. The result: Each individual precision-shaped ceramic grain acts like a cutting tool, slicing through metal like a knife, and continuously self-sharpens as points break off. This allows 3M™ Cubitron™ II abrasive belts, sanding discs, and bonded abrasive wheels to run cooler and keep on working—long after conventional abrasives have dulled, shelled, glazed over and been thrown out.
Watch the Revolution: Reinventing the Cutting Edge

Aligned to Grind Faster, Cooler, Longer

Conventional ceramic abrasive grain is irregular in shape. Instead of a clean, machining action, the grain “plows” through the metal, causing heat build-up, slower cutting and shorter life.

The precision-shaped grain in 3M™ Cubitron™ II grinding wheels continuously fracture to form sharp points and edges – slicing cleaner and faster, staying cooler, and lasting many times longer.
