Features of AC4125K
Excellent chipping resistance is demonstrated by the evolution of high adhesion technology, fine crystal orientation control technology and residual stress control technology, stable machining is utilized in heavy interrupted machining and unstable machining of cast iron. In addition, it adapts a gold color that makes used corners easily identifiable.
Special Surface Treatment
Significantly improves the compressive stress while maintaining the gold color Chipping resistance: Twice as much as conventional types
Al 2 O 3
Fine grain structure greatly improves the coating strength Chipping resistance: Twice as much as conventional types Crystal Orientation Control Ultra-fine Alumina Layer
