Cubitron™ II utilizes 3M™ Precision-Shaped Grain, which outcuts and outlasts conventional ceramic industrial abrasives and requires less grinding force to achieve superior performance. Whether you sand with our new net abrasives, paper-backed or grinding disc varieties, our Cubitron™ II abrasives deliver superior cut and long disc life during key stages in auto body repair.

    3M Precision-Shaped Grain in the Cubitron II discs continuously fractures to form sharp points and edges — slicing cleaner, faster, staying cooler and lasting many times longer

  • Closeup of Conventional ceramic abrasive grain

    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.
