49221 Sanding Disc, 5 In., 120 Grit, Hook & Loop, 8 Hole

The Norton 49221 is a 5-inch sanding disc with 120-grit aluminum oxide abrasive, designed for smooth finishing and surface preparation on wood, metal, fiberglass, and plastics. The hook-and-loop backing allows quick, tool-free disc changes, while the 8-hole pattern works with vacuum systems to collect dust during sanding.

This medium-grit disc works well for general sanding and finishing work. The water-based stearate coating reduces loading, keeping the abrasive particles sharp and active longer. The paper backing is fiber-reinforced and latex-saturated to resist tearing while remaining flexible for use on flat and contoured surfaces.
