IB05H A high speed grade for continuous machining. The 251
binding force between the particles is now improved
by use of coarse PCBN grains which provide excellent
wear resistance results.

H05-H10 Base

IB05S A high speed grade for continuous machining.
The binding force between the particles is now
improved by use of coarse PCBN grains which provide
S05 excellent wear resistance results.

Base

IB10H Extra fine PCBN grain size. Suitable for high speed
machining of hardened steels (45-65 HRC) under stable
