SC Mills intended for specific CT-Motor use for milling cast iron, steels, cements, aluminum, brass, rubber, and plastics by taking a controlled slicing/shaving type of cut which is limited by specific cutter stand-off and back rake. The result is a mill that will cut with very light weight but is not drastically affected by changes in WOB which reduces motor stalling.
