3M 7000118857 Aluminum Oxide Cloth Belt 50 Grit 24x3 in

Product Description

The 3M 7000118857 is an aluminum oxide cloth abrasive belt designed for metal deburring, general metalworking, and woodworking applications. Built on an X-weight cloth backing, this belt handles heavy sanding and grinding demands without breaking down under high heat or pressure. The resin bond locks the abrasive mineral firmly in place, extending belt life in demanding shop and field conditions. At 50 grit, it cuts aggressively enough to remove burrs, parting lines, and surface imperfections on metal and wood substrates. Licensed HVAC, plumbing, and electrical tradespeople regularly use abrasive belts like this for pipe prep, metal fitting cleanup, and panel deburring.

The 341D belt is suited for wide belt, edge, and portable belt sanding setups. Its tube-shaped band geometry fits inner and outer contours, making it effective for profiled workpieces and curved surfaces. It is compatible with rubber expander wheel attachments used with die grinders or rotary drills, giving technicians flexibility across stationary and handheld tools. Appropriate for metal substrates including steel and for general woodworking stock removal.
