The Advantage grinding disc series, from Rex-Cut Abrasives, is for stainless steel and carbon steel, weld bead removal, surface grinding, deburring, chamfering and beveling. They are available in 4 1/2-in. and 5-in. disc sizes in 36 grit for fast stock removal, and 50 grit for a more refined surface finish. The ceramic grain and special backing creates a disc with the toughness of a grinding wheel and the rapid material removal of a resin fiber disc. The ergonomic modified Type 29 shape provides greater disc contact on the work surface to improve metal removal speed.
