BC8210 and BC8220 are the newest innovative PCBN grades for hard turning in continuous, light and medium interrupted cutting applications. The new BC8220 and BC8210 grades exhibit excellent flank and crater wear resistance. Together with increased chipping resistance this provides more stable machining processes and enables long tool life over a wide range of high speed applications. The new BR chipbreaker in combination with BC8220 was developed to provide the advantage of improved chip control during high depth of cut machining. The gold coated outer layer makes it easier for wear detection and easily defines used cutting edges.
