Use 40+ grade discs for paint stripping or body filler rough shaping. 3M precision shaped grain slices through paint and body filler, wears evenly, and provides long life and consistency. These discs utilize the 3M Hookit (Hook & Loop) Attachment System for simple application and reuse.

Triangular-shaped grain (image below) is electrostatically oriented to form sharp peaks, each acting like individual cutting tools that slice through paint and body filler, wear evenly, and provide long life and consistency.
For speed, comfort and long life, nothing else comes close to the power of 3M™ Cubitron™ II Abrasive Discs.


  • 3M Precision-Shaped Grain (PSG) maintains super-sharp points that cut exceptionally fast with less pressure
  • Disc life is significantly longer, completing more vehicle parts per disc and requiring fewer disc changes
  • Triangular-shaped ceramic grain wears evenly, runs cool, and optimizes mineral breakdown
