Norton 78072743976 Abrasive Belt 40 Grit 3-1/2 X 15-1/2 in

Product Description

The NORTON 78072743976 is a coated abrasive belt designed for aggressive material removal in dry grinding and surface finishing applications. Part of the R228 series, this belt is built on a heavy-duty X-weight cloth backing with a closed-coat aluminum oxide abrasive layer. At 40 grit, it falls in the coarse range, making it well-suited for rapid stock removal, weld blending, and rough shaping on metal, wood, and composite surfaces. The closed-coat construction keeps abrasive grain density high across the full belt surface, delivering consistent cut rate throughout the belt life. Licensed trade professionals and fabrication shops rely on this format for portable and stationary belt sander work.

This belt measures 3-1/2 inches wide by 15-1/2 inches long, fitting stationary bench-top belt sanders and portable belt grinding tools that accept this dimension. The aluminum oxide grain is suited for ferrous and non-ferrous metals, hardwoods, and painted or coated surfaces. Dry operation is specified, so this belt should not be used with water, cutting fluids, or wet-application setups. It is commonly used in metal fabrication, welding prep, millwork, and maintenance applications where fast, coarse material removal is the primary goal.

Compatibility

Designed as an OEM-style replacement or standard consumable for belt sanders and grinding tools that accept a 3-1/2 inch by 15-1/2 inch abrasive belt in dry-use applications.

Installation Notes

Belt installation should be performed by qualified personnel familiar with abrasive tool operation. Ensure the sander or grinder is powered off and unplugged before changing belts. Verify belt tracking and tension before resuming operation, and confirm the tool RPM rating does not exceed the belt rating. Eye protection, hearing protection, and appropriate respiratory PPE should be worn during use.
