Norton 78072769230 Abrasive Belt 240 Grit 3x21 Aluminum Oxide

Product Description

The NORTON 78072769230 is a coated abrasive belt designed for dry sanding operations on portable and stationary belt sanders. Built on a heavy X-weight cloth backing with closed-coat aluminum oxide abrasive, this belt delivers consistent cut and finish on wood, metal, and composite materials. The 240 grit rating places it in the very fine grade range, making it well suited for finish sanding passes where surface prep for coatings or final smoothing is the goal. The closed-coat construction maximizes abrasive coverage across the belt surface, reducing skip marks and improving finish uniformity. Metalworkers, woodworkers, and general fabrication tradespeople are the primary users.

This belt fits 3 inches by 21 inches belt sander configurations commonly found in both bench-top and handheld portable units. At 240 grit very fine grade, it is typically used in later-stage sanding sequences after coarser stock-removal grits have been run. Suitable for dry sanding applications only. The R228 series designation indicates the specific abrasive construction line within the NORTON coated abrasives product family. Sold individually, one belt per package.
