Norton 78072733178 Abrasive Belt 150 Grit 3/8x13 in

Product Description

The NORTON 78072733178 is a coated abrasive belt designed for precision material removal and fine surface finishing on power file sanders and narrow belt tools. Running on dry operation only, this belt features aluminum oxide abrasive grain bonded to a heavy X-weight cloth backing with a closed coat density. At 150 grit, it falls in the very fine grade range, making it well suited for final-pass finishing work where surface quality matters. The cloth backing provides flexibility and durability under tension, and the closed coat construction delivers consistent cut and finish on ferrous and non-ferrous metals, wood, and composites.

This belt is sized for narrow belt sanders and power file tools that accept a 3/8-inch wide by 13-inch long configuration. It is a practical choice for detail work, deburring tight profiles, blending welds in confined areas, and finishing contoured surfaces that wider belts cannot reach. Series R228 identifies this as a standard production-grade belt appropriate for shop and field use by machinists, fabricators, pipefitters, and general metal trades professionals.
