3M 7010325827 Abrasive Belt 132x4 Inch P320 Grit

Product Description

The 3M 7010325827 is a coated abrasive cloth belt designed for grinding, blending, deburring, and finishing on metal surfaces. Built with sharp silicon carbide mineral bonded to a tough polyester cloth backing, this belt delivers consistent cut and finish from the start of belt life to the end. The heat-resistant resin bond holds the abrasive firmly under pressure, heat, and wet conditions, making it suitable for both wet and dry applications. At P320 grit, it is positioned for fine finishing passes where surface quality matters. Licensed tradespeople and metal fabricators working at backstand grinders will find this belt a dependable choice for production finishing work.

This belt is sized at 132 inches in length and 4 inches in width, fitting standard backstand grinder configurations used in metal fabrication shops and HVAC duct fabrication, plumbing fitting finishing, and general trade metalwork. The water-resistant polyester backing resists tearing and nicking even under continuous use with coolant or water. The P320 grit rating makes it appropriate for final surface conditioning and light deburring on ferrous and non-ferrous metals.
