3M 7100122890 Ao Cloth Sanding Belt 18x3/4 Inch 60 Grit

Product Description

The 3M 7100122890 is a general-purpose aluminum oxide cloth-backed abrasive belt designed for metal deburring, general metalworking, and woodworking applications. Built on an XF-weight polyester cloth backing, this belt handles both wet and dry use without breaking down under grinding pressure. The resin bond withstands high heat and heavy contact, making it a dependable choice for production and maintenance work alike. At 60 grit, it removes material efficiently on mild steel, carbon steel, aluminum, bronze, and brass. Licensed trade professionals and metalworking shops reach for this belt when consistent cut rates and backing durability matter most.

This belt is suited for use on backstand and benchtop belt sanders, stroke sanders, portable belt grinders, and wide belt grinding and finishing equipment. The 18-inch length and 3/4-inch width fit a common range of industrial and shop-grade machines used in metal fabrication and woodworking facilities. It performs reliably across a broad substrate range, making it a practical stock item for shops that work with multiple materials in the same session.
