The 3M 577F Cloth Belt features a tough alumina zirconia abrasive grain on a durable cloth backing, delivering aggressive stock removal and long-lasting performance on metals, welds, and other hard materials. The coated abrasive construction resists loading and maintains a consistent cut throughout the belt's life.
Ideal for use on portable and stationary belt sanders in industrial, MRO, and fabrication applications, this 80-grit belt measures 3/4 in x 18 in — perfect for tight contours and detail grinding or finishing work. Priced and sold per belt.
