Norton 78072720870 Abrasive Belt 240 Grit 1x42 Aluminum Oxide

Product Description

The NORTON 78072720870 is a coated abrasive belt designed for dry material removal and surface finishing on narrow belt sanders and grinders. Built on a Series R228 platform, this belt features aluminum oxide abrasive grain on a polyester cloth backing with an X-weight designation, delivering durability under tension and heat. At 240 grit, it falls in the very fine grade range, making it well-suited for final stock removal passes, blending, and surface prep before finishing. The closed coat density maximizes abrasive coverage across the belt face, improving cut consistency on each pass.

This belt is sized at 1 inch wide by 42 inches long, a common format used on benchtop and portable narrow belt sanders found in metal fabrication shops, maintenance facilities, and woodworking operations. It is appropriate for dry sanding applications on metals, wood, composites, and similar materials. Trades and craftspeople using this grit level are typically working through final shaping, deburring, or preparing surfaces for paint, coating, or assembly.
