3M 7100044446 Cubitron Ii 732U Disc 5 Inch 120 Grit

Product Description

The 3M 7100044446 is a Cubitron II Hook-It Clean Sanding Paper Disc in the 732U series, engineered for aggressive stock removal on a wide range of substrates. It uses 3M Precision Shaped Grain technology, where triangular ceramic mineral grains are formed to slice through material rather than plow or gouge like conventional abrasives. The result is a disc rated to cut up to 2x faster and last up to 4x longer than standard abrasive discs. At 5 inches in diameter and 120 grit, this disc is suited for surface preparation, paint removal, and material blending tasks where consistent cut rate and disc longevity are priorities.

This disc is designed for use in production and repair environments where stock removal efficiency matters. The precise multi-hole pattern supports superior dust extraction, keeping the work surface visible and reducing loading on the abrasive face. The hook-and-loop attachment system allows for quick disc changes without tools, making it a practical choice for body shops, metal fabrication, woodworking, and general surface prep applications. It is appropriate for use on metals, wood composites, and painted surfaces in both residential and light commercial settings.
