3M 7100205728 Abrasive Belt 24x0.5 Inch P320 Grit Ao Cloth

Product Description

The 3M 7100205728 is an aluminum oxide abrasive belt designed for metalworking applications including light grinding, finishing, deburring, and grain setting. It measures 24 inches in length and 1/2 inch in width, with a P320 grit rating suited for fine finishing work. The belt uses a flexible J-weight cloth backing that conforms to contours and complex part geometries. Open coat construction keeps the belt surface clear of sanding dust, promoting a more aggressive cut and extending abrasive life. A resin bond locks the abrasive to the backing for maximum durability. This belt is intended for dry metalworking use only.

This belt is well suited for use on carbon steel, stainless steel, aluminum, brass, bronze, and copper. It performs in both production and finishing environments where conformability is required. Typical applications include blending weld seams, deburring edges, and setting a consistent surface grain on flat or curved metal workpieces. The belt is designed for use on backstand grinders, file belt tools, and benchtop motors.
