Norton 78072727569 Abrasive Belt 100 Grit 3/4x20-1/2 in

Product Description

The NORTON 78072727569 is a coated abrasive belt designed for precision material removal on metal, wood, and composite surfaces. Built on an X-weight rayon cloth backing, it delivers the rigidity and flexibility needed for contour and flat-surface grinding applications. The belt runs a 100-grit aluminum oxide grain in a closed-coat configuration, providing consistent, medium-grade stock removal. At 0.5 pounds and sized at 3/4 inches wide by 20-1/2 inches long, it fits compact belt grinders and file belt tools commonly used in fabrication and maintenance shops. The Series R283 construction supports both wet and dry operation.

This belt is suited for grinding and finishing tasks in metal fabrication, tool and die work, weld blending, and general maintenance applications. Its closed-coat aluminum oxide grain cuts aggressively at the 100-grit level, making it appropriate for intermediate stock removal and surface preparation before finer finishing passes. The wet/dry rating allows use with cutting fluids to reduce heat buildup on heat-sensitive workpieces, extending belt life in demanding conditions.

Installation Notes

Installation is typically performed by machinists, fabricators, or maintenance technicians. Before changing the belt, disconnect or power down the tool and allow any moving parts to come to a complete stop. Confirm belt tracking and tension per the tool manufacturer guidelines before operating. Inspect the drive and idler wheels for wear or debris that could cause the belt to run unevenly or fail prematurely.
