Norton 78072791377 Abrasive Belt 80 Grit 1x18 Aluminum Oxide

Product Description

The NORTON 78072791377 is a coated abrasive belt designed for dry grinding, blending, and finishing applications on metal, wood, and composite surfaces. Built on a heavy X-weight cloth backing with a closed-coat aluminum oxide grain at 80 grit (medium grade), it delivers consistent, aggressive material removal throughout the belt's working life. The 1-inch by 18-inch format fits compact file belt sanders and detail grinders commonly used in fabrication shops, maintenance environments, and toolrooms. Licensed tradespeople and skilled tradespeople alike rely on this belt format for tight-clearance work where larger belts cannot reach.

This belt is suited for dry-only operation on portable or stationary file belt sanders sized for 1-inch by 18-inch stock. The 80-grit medium grade makes it appropriate for initial stock removal and weld blending on metal, as well as shaping and intermediate smoothing on hardwood and soft metals. It is part of the NORTON R228 series, which is built around a closed-coat aluminum oxide grain structure that resists loading under moderate-pressure passes. Typical users include welders, pipefitters, machinists, and finish carpenters.

Installation Notes

Power down and unplug the sander before installing or removing the belt. Confirm the tracking direction arrow on the belt backing aligns with the machine's drive direction before tensioning. Inspect the platen and contact wheel for wear or damage prior to installing a new belt, as surface irregularities accelerate belt failure. Follow the tool manufacturer's tension and tracking adjustment procedures.
