The 3M 1/2" x 18" 80 Grit Ceramic Aluminum Oxide Medium Abrasive Belt features a ceramic aluminum oxide grain blend ensures that the belt is both efficient and durable, optimizing its use by producing more parts per belt, thus minimizing the need for frequent belt changes. Designed for demanding applications, the belt incorporates a heavyweight polyester backing. This construction supports high-pressure tasks and can be operated in both wet and dry conditions. Additionally, a grinding aid is integrated into the belt to reduce heat buildup, improving its performance on stainless steel and other exotic metals. The resin bond is formulated to resist heat-induced deterioration.
