Norton 78072721997 Abrasive Belt 36 Grit 3-1/2x15-1/2 in

Product Description

The NORTON 78072721997 is a coated abrasive belt designed for aggressive material removal in grinding and shaping applications. Measuring 3-1/2 inches wide by 15-1/2 inches long, it fits belt sanders and finishing machines common in fabrication, woodworking, and metalworking environments. The belt runs a 36-grit, extra-coarse aluminum oxide abrasive on a closed-coat pattern, making it well suited for rapid stock removal, weld blending, and rough surface conditioning. A heavy-duty X-weight cloth backing resists tearing under sustained load and holds up to the heat generated during dry grinding operations. Tradespeople and shop technicians who need a fast-cutting, durable belt for initial shaping and heavy material removal will find this belt performs consistently across multiple passes.

This belt is appropriate for dry-use belt sander applications in metal fabrication shops, cabinet shops, and general maintenance environments. The R228 series aluminum oxide construction performs well on ferrous and non-ferrous metals, hardwood, and painted or coated surfaces requiring stripping. The extra-coarse 36-grit rating positions it as a first-stage belt for multi-step finishing sequences where subsequent passes with finer grits follow. It is sold individually and packaged as a single unit.

Installation Notes

Belt installation should be performed by a qualified operator with the sander powered off and unplugged. Confirm the arrow or directional marking on the belt interior aligns with the machine drum rotation before tensioning. Inspect the platen and contact wheel for wear or debris before seating a new belt. Follow the tool manufacturer torque and tension specifications when tightening the tracking adjustment.
