as a practical tool material.

Uncoated grade that contains 95% PCBN
composed of fine grain size in a special binder.
Used for finishing operations on sintered metals
at high cutting speeds and also for valve seats
and Titanium alloys at continuous up to light
interrupted cutting conditions. Features high
hardness and good wear resistance.
