3M 7100188477 Rapid Removal Sanding Belt 80 Grit 21x3 in

Product Description

The 3M 7100188477 is a rapid removal power sanding belt engineered with Precision-Shaped Grain technology for fast, consistent material removal across a wide range of surfaces. Rated at 80 grit (coarse), the belt measures 21 inches in length by 3 inches in width and is built for use on wood, plastic, and metal. The abrasive construction resists heat buildup and moisture, helping maintain cut rate over the life of the belt. This belt is suited for coating preparation, material removal, and surface leveling stages of sanding work, making it a versatile option for shop technicians, finish carpenters, and metalworkers.

This sanding belt is designed for use with standard 3-inch by 21-inch belt sanders common in woodworking shops, fabrication environments, and light metalworking applications. It performs across multiple sanding stages, from aggressive stock removal at coarse grit to surface prep before finishing coats. The 80 grit rating makes it appropriate for initial leveling passes on wood, paint or rust removal on metal, and shaping of plastic components. Each package contains one belt.
