The mineral makes the wheel cut faster, and the high cut rate is designed to increase efficiency and productivity while leaving a uniform finish. The wheel's 0.125in. profile leads to smoother running with less tendency for vibration, reducing operator fatigue. The wheels are designed for slag removal, descaling and heavy deburring, and removing gates and risers in a variety of metals, including mild steel, iron, stainless steel, aluminum and carbon steel. Available sizes include 4.5 x 0.125 x 0.875 in. and 7 x 0.125 x 0.875 in. in grades 36, 46, 60 and 80.--3M Corp.
