From Ultra-high-speed Turning of Gray Cast Iron to Heavy Interrupted Turning of High-strength Ductile Cast Iron

Features of AC4115K/AC4125K

Utilizing high-adhesion technology between the coating layer and carbide substrate, as well as a technology for micro-structural and crystal orientation control of the Al2O3 layer. Furthermore, advancements in stress control technology achieved through special surface treatment provide excellent wear and chipping resistance. In addition, its gold exterior color makes used corners easily identifiable.

AC4115K
Our 1st recommended grade for turning gray cast iron. Also ideal for continuous turning of ductile cast iron. High-strength coating realizes stable and long tool life.

AC4125K
Our 1st recommended grade for turning of ductile cast iron. In particular, stable and long tool life can be achieved in the roughing of differential cases and carrier cases.
