Norton 78072720476 Abrasive Belt 320 Grit Aluminum Oxide

Product Description

The NORTON 78072720476 is a coated abrasive belt designed for precision finishing and fine material removal on metal, wood, and composite surfaces. Running at 320 grit extra fine grade, this belt delivers consistent scratch patterns suited to final-pass finishing work before coating or polishing. The aluminum oxide abrasive is bonded to an X-weight cloth backing with a closed coat density, providing uniform coverage and extended cut life. At 3/8 inches wide and 13 inches long, it fits compact file belt sanders and inline tools commonly used by fabricators, pipefitters, and maintenance technicians for tight-access deburring and surface prep.

This belt is built for dry operation on stationary or handheld belt sanding equipment that accepts 3/8 inch by 13 inch belts. Typical applications include weld blending, tube and pipe finishing, precision part deburring, and pre-inspection surface preparation. The R228 series designation indicates a cloth-backed construction intended for harder materials where paper-backed belts would break down prematurely. It is sold individually and is well suited to low-volume maintenance use or as a replacement for worn belts in an existing rotation.
