With a multistage grinding operation, superabrasives Cubic Boron Nitride or Borazon abrasives can be used for precision grinding, with stock removal down to 0.004" (0.10mm) achieved. Applications include finishing high speed steel, dies and die buttons, special punches, drill bushings and cutting tools, as well as numerous parts of stainless steel, exotic super alloys, cast iron, and beryllium copper, stellite, etc. Also known to be well suited for work on high-carbon, high-chrome steel, high speed steels such as M2, M3, M4, M7, T1 and T15, and die steels such as D2, D3, D7 and A & O series. Various super alloys which are regarded as "difficult", also respond favorably to these superabrasives.
