3M 7010307969 Cloth Sanding Belt 40 Grit 70.5x10 Inch Ao

Product Description

The 3M 7010307969 is an aluminum oxide cloth sanding belt designed for metal deburring, general metalworking, and woodworking applications. Known as the 341D series, this belt features an X-weight cloth backing that holds up under heavy sanding and grinding loads. The resin bond resists high heat and pressure, making it suitable for sustained use on metal substrates and wood. At 70.5 inches long and 10 inches wide with a 40-grit cut, this belt is built for wide belt, edge, and portable belt sanding equipment. Tradespeople and fabricators working in metal finishing and surface prep will find it well-suited to their production workflows.

This belt fits wide belt sanders, edge sanders, and portable belt sanders. Its tube-shaped band construction also allows it to fit over a rubber expander wheel attachment for use with a die grinder or rotary drill, making it adaptable for contouring and accessing inner and outer profiles. It is appropriate for use in fabrication shops, metal finishing operations, and woodworking facilities where consistent stock removal and surface conditioning are required.
