Norton 78072727927 Abrasive Belt 40 Grit 3x21 in

Product Description

The NORTON 78072727927 is a coated abrasive belt designed for aggressive material removal in dry grinding and sanding applications. Part of the R228 series, it features aluminum oxide abrasive grain on a heavy-duty X-weight cloth backing with a closed coat density. The 40-grit extra coarse grade makes it well suited for rapid stock removal, weld blending, and surface shaping on metal, wood, and similar workpiece materials. The closed coat construction maximizes abrasive coverage per square inch, supporting consistent cut rate across the life of the belt. Licensed tradespeople and skilled shop technicians are the primary users of this product.

This belt is used in portable belt sanders and stationary belt sanding machines that accept a 3-inch wide by 21-inch long belt. It is a common choice for metal fabrication shops, woodworking operations, and maintenance facilities where fast, aggressive cutting is needed before moving to finer finishing stages. The dry-only rating means it should not be used with water, cutting fluids, or other liquid coolants, as these will compromise the cloth backing and abrasive bond.

Installation Notes

Belt sander installation should be performed with the tool unplugged or the power source locked out before changing belts. Verify belt tracking adjustment after installation and before applying the belt to a workpiece. Inspect the belt for tears or edge damage before use, and never operate a damaged belt.
