3M 7100141431 Cloth Sanding Belt 80 Grit 30x1 Inch Ao

Product Description

The 3M 7100141431 is an aluminum oxide cloth-backed abrasive sanding belt designed for general-purpose material removal across metal and wood substrates. Running at 80 grit with an XF-weight polyester cloth backing, it handles the heat and pressure of aggressive grinding and heavy sanding cycles without breaking down. The resin bond keeps the abrasive mineral locked in place under sustained load. Measuring 30 inches in length and 1 inch in width, this belt fits standard benchtop and backstand belt sanders used in metal fabrication and woodworking shops. Experienced tradespeople and shop technicians rely on this belt for consistent cut rates and finish results across production and maintenance applications.

This belt is optimized for deburring and general metalworking on mild steel and carbon steel. It also performs effectively on softer nonferrous metals including aluminum, bronze, and brass, as well as select woodworking tasks. Suitable mounting configurations include backstand and benchtop belt sanders, stroke sanders, portable belt grinders, and wide belt grinding and finishing machines. It is rated for both wet and dry use, making it adaptable to coolant-assisted or dry grinding setups common in metal fab environments.
