3M 7010308385 Cloth Sanding Belt 50 Grit 36x4 Inch Ao

Product Description

The 3M 7010308385 is an aluminum oxide cloth sanding belt designed for metal deburring, general metalworking, and woodworking applications. Built on an X-weight cloth backing, this belt handles heavy sanding and grinding loads without breaking down. The resin bond system resists high heat and pressure, making it suitable for demanding shop use. The aluminum oxide abrasive cuts fast across metal and wood substrates and maintains consistent performance through extended use. This belt is sized at 36 inches long by 4 inches wide and carries a 50-grit rating. It is installed and used by machinists, metalworkers, fabricators, and woodworking professionals who rely on consistent stock removal and surface finishing.

This belt is suited for wide belt sanders, edge sanders, and portable belt sanding equipment. The tube-shaped band design allows it to fit inner and outer contours, making it effective for removing parting lines, imperfections, and burrs from metal parts. It also fits onto a rubber expander wheel attachment for use with a die grinder or rotary drill, expanding its range of use across portable and stationary applications. Typical uses include deburring cast or machined metal components, blending welds, and surface preparation on metal and wood workpieces.
