The 3M 6" x 48" 120 Grit Coated Ceramic Aluminum Oxide Fine Abrasive Belt features a ceramic and aluminum oxide grain blend designed for cut-rate performance over standard aluminum oxide abrasives. The heavyweight polyester backing provides exceptional support for high-pressure and demanding applications, and it can function effectively in both wet and dry conditions. Additionally, the belt is equipped with a grinding aid, which works to lower the heat generated during use and boosts performance when working with stainless steel and exotic metals. The resin bond used in this belt is engineered to resist the detrimental effects of heat, further prolonging the belt’s service life.
