3M 7100128750 Abrasive Belt 80 Grit 15.5x3.5 Inch Ceramic

Product Description

The 3M 7100128750 is a coated abrasive cloth belt engineered for metal finishing and stroke sanding applications. It uses a blend of ceramic aluminum oxide grain on an X-weight cotton backing, delivering aggressive cut rates and extended belt life compared to standard aluminum oxide products. The 80-grit designation makes it well suited for material removal and surface preparation on ferrous and non-ferrous metals. A built-in grinding aid reduces heat buildup during extended use, protecting both the workpiece and the abrasive. Anti-friction backing treatment helps the belt track and run smoothly on contact wheels and platens. This belt is manufactured for professional metalworking environments where consistent finish quality and belt longevity are priorities.

This belt is used in industrial and shop environments for stroke sanding, centerless grinding, and surface finishing on metals including stainless steel, nickel alloys, and carbon steel. It is appropriate for fabrication shops, weld prep and weld blending operations, and metal service centers. The 15.5-inch length and 3.5-inch width fit a range of stroke sanders and backstand grinders common in trade and light-industrial settings. Metalworkers, fabricators, and finishing technicians are the primary installers and users of this product.
