   3M™ Cubitron™ II Abrasives


With decades of experience in ceramic, abrasive and microreplication technologies, 3M has literally reinvented abrasives with Cubitron™ II products. Starting with a patented, precision-shaped ceramic abrasive grain, 3M engineers found a way to electrostatically orient each triangular structure to maximize 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 Belts and Discs to run cooler and keep on working—long after conventional abrasives have dulled, shelled, glazed over and been tossed out.

Unique 36+ grade for a revolutionary product

Multiple grading systems have been created as mineral technology evolves and Cubitron II abrasives are no exception. Engineered triangular shapes can’t be boxed into the screens currently used for grading. But you’ll see how this new mineral cuts with all the speed and life you’d expect from an ANSI 36, plus more. Since finish results depend on the mineral size, variations in applications, and operator technique, 3M field support is available to help refine any scratch on any metal.

No matter how you cut it, Cubitron II Discs work harder

Push yourself to the limit or let the disc do the work, either way, 982C removes an average of 40% more material than comparable fibre discs. Finish more parts with fewer discs regardless of grinding pressure

When it comes to grinding 304 stainless steel, 3M™ Cubitron™ II Fibre Discs are in a class by themselves (see chart). Within 15 minutes of grinding, Cubitron™ II 982C discs removed nearly twice as much material as the next best ceramic disc.


This premium fibre disc features 3M's patented new ceramic mineral. Designed for carbon steel metalworking applications such as weld grinding, beveling, flame-cut edge clean-up, and deburring.

Benefits and Features:
  • ^
  • Precision-shaped abrasive grain
  • 2X life
  • Fastest cut
  • Cool running
  • Use wet or dry
  • Complete carbon steel solution


    As a no-nonsense person, your success comes from results, not hype. You may doubt that you and a grinding disc or belt can start a revolution.

    But if you could reduce your abrasive costs, increase part throughput, better leverage your capital equipment, decrease metal repair and lower your manufacturing costs—all with abrasive products that cut faster, last longer and require less grinding pressure—you would truly revolutionize the way you work.

    And that's what 3M™ Cubitron™ II abrasives do. Try a fibre right angle grinder disc or metalworking belt now and find out for yourself. Get your free 3M™ Cubitron™ II Abrasives sample here.
