3M 7100033224 Abrasive Belt P320 Grit 48x6 Inch Ao Cloth

Product Description

The 3M 7100033224 is an aluminum oxide cloth abrasive belt designed for metal deburring, general metalworking, and woodworking applications. Built on an X-weight cloth backing, it handles heavy sanding and grinding demands without breaking down under high heat or pressure. The resin bond holds the abrasive mineral firmly in place, allowing the belt to cut fast across metal and wood substrates. At P320 grit, it delivers fine stock removal and surface refinement. Licensed HVAC techs, metalworkers, and fabricators reach for this belt when cleaning parting lines, removing burrs, or blending weld seams on metal parts.

This belt measures 48 inches in length and 6 inches in width, making it suitable for wide belt sanders, edge sanders, and portable belt sanding equipment. The tube-shaped band construction also fits onto a rubber expander wheel attachment for use with a die grinder or rotary drill, expanding its range to inner and outer contours where flat sanders cannot reach. It is well-suited for both production metalworking environments and general fabrication shops working with metal or wood substrates.
