Norton 78072771432 Abrasive Belt 320 Grit Aluminum Oxide

Product Description

The NORTON 78072771432 is a coated abrasive belt designed for dry precision finishing applications. Built on a heavy-duty X-weight cloth backing with closed-coat construction, it delivers consistent aluminum oxide cutting action across the full belt surface. At 320 grit, it falls in the extra fine grade range, making it well-suited for final-pass surface prep, light stock removal, and finishing work where surface quality matters. The belt measures 3-1/2 inches wide by 15-1/2 inches long and weighs 0.3 pounds. It is part of the R228 series and is intended for use on stationary or portable belt sanders by trade professionals and skilled fabricators.

This abrasive belt is used in metal fabrication, woodworking, and finishing operations where a controlled, fine surface finish is required. The closed-coat aluminum oxide construction keeps abrasive grain packed tightly across the backing, which maximizes cut consistency on flat and contoured workpieces. Dry operation only. Typical applications include finish sanding of wood components, light deburring of metal parts, and surface conditioning before coating or inspection. It is appropriate for both shop and field use wherever a compatible belt sander is available.

Installation Notes

Belt sander abrasives should be installed by operators familiar with the equipment manufacturer guidelines. Power down and disconnect the sander from its power source before changing belts. Confirm belt tracking alignment before resuming operation, and inspect the belt for tears or edge damage prior to use. Do not use this belt for wet sanding applications.
