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