3M™ Cubitron™ II Abrasives for Metalworking

Time is money. That’s why metalworkers around the world count on fast-cutting, long-lasting 3M™ Cubitron™ II Abrasives. These premium abrasives belts, discs and wheels are powered by 3M Precision-Shaped Grain — the result of decades of technological advances in ceramic abrasive and microreplication technologies. 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.

The bottom line: 3M™ Cubitron™ II Abrasives cut faster, last longer, and help lower your production costs.
