Norton 78072722071 Abrasive Belt 320 Grit 4x36 Aluminum Oxide

Product Description

The NORTON 78072722071 is a coated abrasive belt designed for precision surface finishing on belt sanders and similar abrasive machinery. Running 4 inches wide by 36 inches long, this belt carries a 320-grit aluminum oxide abrasive on an X-weight polyester cloth backing. The extra-fine grit rating makes it well suited for final finishing passes, light stock removal, and surface preparation before coating or sealing. The closed-coat density provides consistent scratch patterns across the full working surface. Dry operation only. Licensed trade and industrial users install and replace these belts as part of routine machine maintenance and finishing workflows.

This belt fits standard 4 x 36 inch belt sander platforms commonly used in metal fabrication shops, woodworking operations, HVAC duct and component fabrication, and general industrial maintenance. The R228 series designation identifies it within the NORTON coated abrasives line. At 320 grit, it is appropriate for smoothing welds, deburring metal edges, and final wood surface conditioning prior to staining or finishing. Dry use only — do not apply coolants or cutting fluids with this belt.
