Rapid Material Removal Made Easy. When quick leveling is needed try one of our coarse Alumina Zirconium bands with our Expander Wheel (13079). These bands cut twice as long as Aluminum Oxide with higher contact pressure and they cut more smoothly and efficiently than a grinding wheel! Even levels hard metal surfaces like weld beads! This band is 50 grit and measures 1 1/2in. wide by 18 15/16in. to fit our Expander Wheel (13079).
