Cubitron II

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.

  • Belts

    From robots to backstands to cylindrical grinders and anywhere else you need an abrasive belt to take on your toughest materials, 3M™ Cubitron™ II Belts will be your go-to choice. Heat-sensitive metals stay cool for less rework and scrap. Belt grinding and sanding equipment run more efficiently with fewer changeovers. And productivity rises to a whole new level.

  • Cut-Off Wheels

    3M™ Cubitron™ II Cut-Off Wheels are designed to provide high cut rates on all types of ferrous metals, stainless steels, alloy steels and cast iron. They offer long life to help reduce cost. Plus, their fast, cool cutting action helps make your job easier!

  • Fibre Discs

    3M Fibre Discs are an ideal choice for applications like weld removal, beveling, edge chamfering and more – offering a faster cut and longer life than alumina zirconia (AZ) and conventional ceramic abrasives.

  • Flap Discs

    3M™ Cubitron™ II Flap Discs let you breeze through a wide range of tough jobs around the shop, including grinding, weld removal, deburring and more. These smooth-running wheels are designed to cut with less pressure. They include a grinding aid to help maintain cutting efficiency on heat-sensitive metals. And, because they are made with 3M precision-shaped grain, they keep on cutting – long after other flap discs have called it quits!

  • Depressed Center Grinding Wheels

    3M™ Cubitron™ II Depressed Center Grinding Wheels are fast cutting, long lasting, and require less pressure. These cool cutting wheels are ideal for heavy grinding and weld removal. Specially formulated for use on stainless and mild steel. Available with quick change attachment.

  • Sanding Discs

    These discs are ideal for a broad range of applications focused primarily on stock removal, and are effective on a wide variety of substrates, including metals, composites, gelcoat, and whitewood.

Technology Spotlight | How is 3M different?

Introducing the 3M™ Cubitron™ Precision-Shaped Grain

The science of speed.

  • Why 3M precision shaped grain abrasive technology is different from conventional ceramic abrasive grain technology

    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.
