3M 7100122770 Aluminum Oxide Cloth Belt 80 Grit 48x6 in

Product Description

The 3M 7100122770 is an aluminum oxide cloth-backed abrasive belt designed for general-purpose metalworking and woodworking applications. Running on a polyester waterproof backing rated at XF weight, this belt handles both wet and dry service without delaminating under load. The resin bond resists high heat and pressure generated during aggressive stock removal. At 80 grit, the belt removes material efficiently while maintaining a consistent scratch pattern across the workpiece. It is sold individually and suited for production and maintenance environments where reliable, repeatable abrasive performance is required across a range of substrates.

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 also suitable for some woodworking operations. Compatible with backstand and benchtop belt sanders, and rated for stroke sanding, portable belt grinding, and wide belt grinding and finishing operations. The 48 inch length and 6 inch width fit commonly available industrial belt sanding machines used in metal fabrication shops, maintenance facilities, and woodworking operations.
