The 3M 3-1/2" x 15-1/2" 80 Grit Ceramic Aluminum Oxide Medium Abrasive Belt features a unique blend of ceramic and aluminum oxide grains, which provides a superior cut-rate compared to traditional aluminum oxide abrasives. It is engineered with a heavyweight polyester backing that supports high-pressure and tough applications, compatible with both wet and dry operations. The inclusion of a grinding aid is designed to reduce generated heat, thereby enhancing the belt's performance when working with stainless steel and other heat-sensitive exotic metals. Additionally, the durable resin bond is crafted to resist heat-induced deterioration, contributing to the belt's longevity and operational efficiency.
