3M 7100185687 Abrasive Belt 132x4 in P400 Silicon Carbide

Product Description

The 3M 7100185687 is a silicon carbide abrasive cloth belt engineered for grinding, blending, deburring, and finishing on metal surfaces. The belt uses sharp silicon carbide mineral that fractures consistently during use, maintaining a uniform cut rate and surface finish throughout the belt's service life. A heat-resistant resin bond locks the abrasive to a tough polyester cloth backing, keeping the mineral secure under pressure, heat, and wet conditions. At P400 grit, this belt is suited for fine finishing work where surface quality matters. HVAC fabricators, metalworkers, and industrial maintenance techs are the primary users.

This belt measures 132 inches in length and 4 inches in width, making it a standard fit for backstand belt grinders and industrial finishing machines used in metal fabrication shops, HVAC sheet metal work, and general industrial maintenance. The polyester cloth backing supports both wet and dry applications, from heavier stock removal to fine surface blending. The flexible cloth construction allows the belt to conform to contoured or irregular workpiece profiles without tearing or nicking at the edges.
