3M 7010294519 Cloth Sanding Belt 60 Grit 21x3 Inch Ao

Product Description

The 3M 7010294519 is an aluminum oxide cloth abrasive belt designed for metal deburring, general metalworking, and woodworking applications. The 341D series belt features a durable X-weight cloth backing that handles heavy sanding and grinding loads, paired with a resin bond system that resists heat and pressure buildup during extended use. At 60 grit, this belt cuts aggressively while maintaining consistent performance across metal and wood substrates. It is installed by machinists, fabricators, and finishing technicians using wide belt sanders, edge sanders, or portable belt sanders in shop and field environments.

This belt is suited for both residential shop and light industrial metalworking applications. Its tube-shaped form fits inner and outer contours, making it effective for removing parting lines, weld spatter, surface imperfections, and burrs from metal workpieces. It is also compatible with a rubber expander wheel attachment used with a die grinder or rotary drill, expanding its range of use in tight or contoured areas. Woodworking applications including surface prep and finish sanding on wood substrates are also supported.
