Norton 78072727926 Abrasive Belt 50 Grit 3x21 in

Product Description

The NORTON 78072727926 is a coated abrasive belt designed for aggressive material removal on portable and stationary belt sanders. Running on a dry basis, this belt uses aluminum oxide grain in a closed-coat configuration bonded to an X-weight cloth backing. At 50 grit, it falls in the coarse grade range, making it well-suited for rapid stock removal, weld grinding, and surface shaping on metal, wood, and composites. The R228 series designation indicates a resin-over-resin bond system engineered for heat resistance and grain retention under sustained load. Tradespeople and fabricators reach for this belt when fast cutting action and backing durability are the priority.

This belt is used in general fabrication shops, metal finishing operations, and woodworking environments where a portable belt sander or stationary grinder accepts a 3-inch by 21-inch belt. The coarse 50-grit cut makes it appropriate for first-pass work: removing mill scale, leveling welds, stripping old coatings, or rough-shaping wood stock before moving to a finer grit sequence. The X-weight cloth backing resists tearing under high pressure, supporting aggressive plunge cuts and edge work. It is sold individually per package with a minimum order quantity of 10 units.

Key Features

• Aluminum oxide abrasive grain for consistent, fast-cutting performance on metal and wood
• 50 grit coarse grade suited for rapid stock removal and surface shaping
• Closed-coat configuration maximizes grain density for aggressive cutting action
• X-weight cloth backing provides tear resistance under high-pressure applications
• Dry-operation design compatible with standard portable and stationary belt sanders
• R228 series resin-over-resin bond for heat resistance and extended grain retention

Compatibility

Designed as a direct-fit replacement belt for portable and stationary belt sanders that accept a 3-inch wide by 21-inch long abrasive belt.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians familiar with belt sander tooling. Before changing the belt, disconnect the tool from its power source or lock out the power switch per standard OSHA lockout-tagout procedures. Seat the belt with the arrow on the inside face aligned to the direction of sander rotation where marked. Verify belt tension and tracking before returning the machine to service.
