Product Description

The 3M 7100020317 is a coated abrasive cloth belt in the 361F series, designed for demanding metal finishing and fabrication work. Built on a tough polyester backing with aluminum oxide abrasive grains bonded by a heat-resistant resin system, this belt delivers consistent stock removal across grinding, blending, deburring, and finishing operations. At 75 inches long and 37 inches wide with an 80 grit cut, it is sized for high-throughput applications where both durability and surface consistency matter. Licensed tradespeople and fabrication shop operators are the primary users of this belt.
