The DS chipbreaker creates well controlled AH6030 with high reliability allows longer tool
chips and the AH6030 provides longer tool life life. When machining super alloys such as
with improved chipping resistance. Inconel, inserts with higher number of corners
are very effective for reducing tool cost.
