Camel Grinding Wheels offers a line of semi-flex discs for aggressive grinding applications which are engineered not to load up while working. Semi-flex discs are uniquely shaped to provide maximum chip clearance and air flow for longer working life and increased production times. CGW's aluminum oxide semi-flex discs are available in 4" and 7" diameters, 16-36 grit sizes and type 27 shape. Aluminum oxide semi-flex discs are recommended for removing rubber from gas pipe ends and grinding cold rolled steel, stainless steel, bronze and iron.
