Norton 78072728643 Abrasive Belt 80 Grit 2x72 in

Product Description

The NORTON 78072728643 is a coated abrasive belt designed for aggressive stock removal on metal, wood, and composite surfaces. It measures 2 inches wide by 72 inches long and runs on standard belt grinders and file belt machines common in fabrication and finishing shops. The abrasive grain is zirconia alumina, a self-sharpening material that maintains cut rate longer than aluminum oxide under heavy pressure. Grit is 80, placing it in the coarse range for fast material removal and weld blending. The polyester cloth backing resists tearing and heat buildup during extended runs.

This belt is suited for stationary and portable belt grinders used in metal fabrication, structural steel work, pipe fitting, and general grinding applications. The closed-coat construction provides a dense abrasive surface that works efficiently on ferrous and non-ferrous metals. Both wet and dry operation are supported, making it compatible with coolant-assisted grinding setups as well as dry bench operations. It is sold individually and is part of the Series R823P line.
