3M 7100128751 Abrasive Belt 24x0.5 in 80 Grit Aluminum Oxide

Product Description

The 3M 7100128751 is an aluminum oxide cloth-backed abrasive belt designed for general-purpose metalworking and woodworking tasks. At 24 inches long and 1/2 inch wide with an 80-grit cut, this belt is built for moderate stock removal and surface conditioning. The XF-weight polyester cloth backing provides the rigidity and durability needed for demanding grinding and heavy sanding applications. A resin bond system holds the abrasive mineral firmly under high heat and pressure, extending belt life in production and job-site environments. Fabricators, metalworkers, and finishing technicians rely on this belt for consistent, repeatable results across a broad range of substrates.

This belt is suited for deburring mild steel and carbon steel, as well as finishing softer metals including aluminum, bronze, and brass. It also performs in woodworking finishing applications. The 1/2-inch width and 24-inch length make it compatible with backstand and benchtop belt sanders, stroke sanders, portable belt grinders, and wide belt grinding and finishing machines. The waterproof polyester backing supports both wet and dry sanding operations, making it adaptable to shop environments where coolant or water is used during metal fabrication.
