Selection Insert Recommended Grades and Chipbreakers Cast Iron Grades AC405K / AC415K / AC420K AC405K: Suitable for high-speed continuous cutting. Excellent resistance to wear and plastic deformation. AC415K: First recommended grade for cast iron turning. Provides stability and long tool life in a wide range of processes. AC420K: Superior fracture resistance provides excellent stability in interrupted unstable cutting and when cutting mill-scaled work. l Improvements to super FF-TiCN coating grain and hardness provide significantly improved wear resistance. Newly developed stress control technology enhances micro-grained α Alumina (FF-Al2O3) coating for superior reliability. l Coating Structure Coating stress control technology reduces abnormal Micro-grained α Alumina (FF-Al2O3) damage caused by chipping. Improved adhesion and peel-off resistance. Chipping Super FF-TiCN Ultra-fine grained, ultra-hard TiCN coating increases wear resistance 1,5 times.
