G (CBN tool). Also, KBN25M has increased its tool life up to 250 pieces/edge by hanging · Furthermore it still keeps the insert in a good condition and so provides stable machining result. from wet machining to dry machining. ⇒Its longer tool life and capability of providing stable result can contribute to cost-cutting and improved efficiency in machining.
