Norton 78072766143 Abrasive Belt 80 Grit Aluminum Oxide

Product Description

The NORTON 78072766143 is a coated abrasive belt designed for precision material removal on narrow surfaces. Measuring 0.25 inches wide by 12 inches long, it uses aluminum oxide abrasive grain bonded to an X-weight rayon cloth backing for durability under load. The closed-coat construction delivers consistent 80-grit (coarse) cutting action across the full belt surface. This Series R283 belt supports both wet and dry operation, making it suitable for metalworking, woodworking, and finishing applications where a small-profile belt tool is required. Machinists, fabricators, and finishing technicians are the primary users.

This belt fits narrow file belt sanders and similar small-format belt tools used in deburring, contour sanding, and tight-clearance finishing. The 80-grit coarse grade is best suited for stock removal, weld blending, and surface prep before finer finishing passes. The X-weight rayon cloth backing resists tearing under moderate-to-heavy pressure, making it a reliable choice for repetitive production use as well as shop-floor maintenance tasks.
