Product Spotlight

YBC152 Black Diamond Coating Grade


YBC152 comprises of thick layer of TICN and Al2O3 in CVD coating process which yields anti-plastic deformation and strong cutting edge strength.  It's the preferred choice for machining steel from finish to semi-finish in high speed under general condition

Perfect unification of toughness and anti-plastic deformation


The two areas on the outside of the red line are ductile area of rich cobalt layer while the middle section contains cubic carbides of well high-temperature behavior.  This unique skeleton design on the cutting edge improves toughness and anti-plastic deformation.


Improved Surface Roughness

           Before Treatment                               After Treatment

Special surface treatment on the insert significantly lower the surface roughness, reduces the bonding between insert surface and work material, effectively improves the stability.

Combination of fibrous TICN and fine grained Al2O3 increases abrasion resistance and anti-chipping.

HF Chip Breaker


preferred choice chip breaker on General Purpose Finishing

M Class tolerance double sided chip breaker, suitable for alloy steel and cast iron's boring and outside turning in finishing cut.
