Fibers and sharp abrasive particles are bound together to form an open, three-dimensional structure that allows fresh abrasive to be exposed as the disc wears, resulting in longer life and helping to deliver consistent performance
Multi-hole pattern maximizes dust extraction with a central or self-generated vacuum system (sold separately)
Medium density foam provides some conformability for surface sanding
Tapered edge performs well when flexibility is needed for feather-edging or blending a painted area
External threads are compatible with orbital or random orbital sanders with similar internal threads (1/4-20 for 3" random orbital sander or 5/16-24 for 5" and 6" random orbital sanders)
3M™ Hookit™ hook-and-loop attachment provides excellent backing support and easy reuse, optimizing disc life
