Triangular-shaped grain 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.

50 Disc/Box
