The 3M 1-1/2" x 60" 120 Grit Coated Ceramic Aluminum Oxide Fine Abrasive Belt features a specialized grain blend that surpasses traditional aluminum oxide abrasives in cut-rate efficiency. This blend of ceramic and aluminum oxide is engineered to enhance durability, producing a higher number of parts per belt, resulting in fewer belt changes. The belt is constructed with a heavyweight polyester backing, which supports high-pressure and demanding applications, and it has the versatility to be utilized wet or dry. Additionally, the belt incorporates a grinding aid that helps in reducing heat buildup, thus optimizing performance when working with stainless steel and other exotic metals. The robust resin bond construction effectively resists heat-induced deterioration.
