KBN25M improved tool life up to 70 pieces/edge, two times more than competitor's G (CBN tool).• KBN35M achieved 15% Longer tool life in heavy interrupted machining compared with competitor H.
Also, KBN25M has increased its tool life up to 250 pieces/edge by hanging from wet machining to• Furthermore it still keeps the insert in a good condition and so provides stable machining result.
dry machining.• Its longer tool life and capability of providing stable result can contribute to cost-cutting and
improved efficiency in machining.
