3M 7010327803 Cloth Sanding Belt 42 Inch 1 Inch 120 Grit

Product Description

The 3M 7010327803 is a general-purpose aluminum oxide cloth-backed abrasive belt designed for metal deburring, general metalworking, and woodworking applications. At 42 inches long and 1 inch wide with a 120-grit aluminum oxide mineral, this belt delivers consistent stock removal across a broad range of substrates. The XF-weight polyester cloth backing handles both wet and dry use, while the resin bond resists high heat and pressure generated during sustained grinding and sanding operations. Licensed tradespeople and shop technicians reach for this belt when they need dependable, repeatable results across production runs.

This belt is optimized for use on mild steel and carbon steel and performs well on softer metals including aluminum, bronze, and brass. It is suitable for use on backstands, benchtop belt sanders, portable belt grinders, and wide belt grinding and finishing equipment. Stroke sanding applications are also supported. The maroon-colored belt is well-suited to mid-range finishing passes where a 120-grit cut is the appropriate stock-removal step before final surface prep.
