About 3M™ Cubitron™ II Abrasives

  • With decades of experience in ceramic, abrasive and microreplication technologies, 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.

Technology Spotlight | How is 3M different?

Introducing the 3M Precision-Shaped Grain

The science of speed.

  • The precision-shaped grain found in 3M™ Cubitron™ II Abrasives combines the advanced material properties of our original Cubitron grain with the precise microreplicated structures pioneered in 3M™ Trizact™ Abrasives. As the triangular shaped grain wears, it continuously fractures to form sharp points and edges.

    Conventional ceramic abrasive grain is irregular and blocky in shape. Instead of a clean, machining action, the grain tends to “plow” through the metal, causing heat to build up in the workpiece and the abrasive — resulting in a slower cut, shorter belt life and undesirable effects, such as burnishing.
