Norton 78072722543 Abrasive Belt 320 Grit 6x48 in

Product Description

The NORTON 78072722543 is a 6 x 48 inch coated abrasive belt designed for dry precision finishing on belt sanders and stationary abrasive machines. Built on an X-weight polyester cloth backing, it delivers the rigidity and flexibility needed for consistent stock removal and fine surface finishing. The 320 grit aluminum oxide abrasive is closed-coat and rated Extra Fine, making it well-suited for final finishing passes where surface quality matters. At 0.05 pounds, the belt is lightweight and easy to handle during changeovers. This is a Series R228 belt intended for professional metalworking, woodworking, and composite finishing applications.

The 78072722543 is used in dry grinding and finishing operations across metalworking shops, woodworking facilities, and maintenance environments. The 6 x 48 inch format fits a wide range of floor-standing and benchtop belt sanders. At 320 grit Extra Fine, this belt is typically used in the final stages of a multi-step finishing sequence, following coarser grits to achieve a smooth, refined surface. It is appropriate for use on ferrous and non-ferrous metals, hardwoods, softwoods, and certain composites in both production and job-shop settings.

Installation Notes

Belt installation should be performed by a qualified operator with the machine powered off and unplugged or locked out per OSHA lockout/tagout procedures. Verify belt tracking and tension before resuming operation, and confirm belt direction-of-travel arrow aligns with machine rotation if marked. Inspect the belt for cracks, damaged splices, or delamination before each use and replace immediately if defects are found. Dry-use belts must never be used with water, coolant, or cutting fluid.
