Norton 78072746387 Abrasive Belt 320 Grit 2x48 in Aluminum Oxide

Product Description

The NORTON 78072746387 is a coated abrasive belt designed for dry finishing and surface preparation on a belt sander or similar abrasive-drive equipment. Running 2 inches wide by 48 inches long, this belt uses 320-grit aluminum oxide in a closed-coat configuration on a polyester cloth backing with an X-weight rating, making it well suited for fine stock removal, blending, and finish work on metal, wood, and composite surfaces. It belongs to NORTON's R228 series and is sold individually.

This belt is appropriate for trade and industrial use where a fine-grit, extra-fine grade finish pass is required before final polishing or coating. Typical applications include deburring light tool marks, smoothing weld seams, and preparing surfaces for paint or primer in metal fabrication, woodworking, and general maintenance shops. Its closed-coat aluminum oxide construction maintains consistent cut throughout the belt's service life on dry operations.

Installation Notes

Installation is performed by qualified technicians or experienced tradespeople familiar with abrasive belt equipment. Power down and unplug the belt sander before changing belts. Confirm belt tracking direction matches the arrow printed on the belt's inner seam before tensioning. Inspect the drive and idler rollers for wear or debris that could cause premature belt failure.
