The 3M 3/4" x 18" 80 Grit Ceramic Aluminum Oxide Medium Abrasive Belt features a ceramic aluminum oxide grain blend that offers an improved cut-rate over traditional aluminum oxide abrasives. This blend enhances the longevity of the belt, allowing for increased productivity and fewer belt changes. The heavyweight polyester backing is designed to withstand high-pressure, tough applications and is suitable for both wet and dry use. For optimized performance on stainless steel and other exotic metals, the belt contains a grinding aid that minimizes heat buildup. A durable resin bond further enhances the belt's resistance to heat-related deterioration, thus extending its operational life in demanding environments.
