KBN25M improved tool life up to 70 pieces/corner that is two times more than competitor's (CBN
tool) B. Also, KBN25M has increased its tool life up to 250 pieces/corner by changing from wet
machining to dry machining.

Competitor's (CBN tool) C required many corrections in order to accomplish 250 pieces/corner,
and its tool life was not stable.KBN25M (with wiper edge) exhibited good wear resistance at the
insert edge, and the edge condition is capable of further extension of tool life.
