Basic grade
Supplemental grade
AC052P P05(P01-P15) CVD coated grade, has good crater resistance and chipping resistance, which is recommanded for high productivity medium and rough turning in stable condition, can keep edge reliability in dry or wet machining with high temperature. AC150P P15(P10-P25) CVD coated grade, can be used in finish to rough turning on steel and cast steel, and is recommanded in continuous and light interrupted cutting where it can keep high metal removal rate. AC250P P25(P20-P35) CVD coated grade, 1st choice for steel turning, used in finish to rough turning on steel and cast steel. It's recommanded for ccontinuous and interrupted machining. AC350P P35(P25-P45) CVD coated grade, can be used in rough turning on steel and cast steel under poor conditions. Reliable cutting edge made this grade good for interrupted machining with high metal removal rate.
AP200U P25(P15-P35) PVD coated grade, recommanded for finish turning on low carbon steel with low cutting speed or low feed. AC200M P35(P25-P40) CVD coated grade. Supplemental grade for steel turning with high toughness requests. AT202 P15(P10-P20) Uncoated cermet grade. It has excellent built-up edge resistance and chipping resistance which can be used in finish turning with good surface quality or low cutting force requests.
Austenitic stainless steel, cast steel, manganese steel, alloyed cast iron, malleable cast iron and free cutting iron.

Basic grade
Supplemental grade
AC100M M15(M05-M20) CVD coated grade. It's recommanded for finish machining and light rough machining. It's suitable for machining at medium to high cutting speed due to its heat resistance feature of wear resistant coating. AC200M M25(M15-M30) CVD coated grade, optimised for semi-finish to rough turning, can be used in interrupted machining in which it can keep edge reliability due to good thermal shock stability and mechanical shock resistance. AP200U M25(M15-M35) PVD coated grade, used in finish turning at low to medium speed and also in interrupted turning due to excellent thermal stability, outstanding performance in machining when sharp edge and edge toughness or good surface quality are requested. AP301M M25(M15-M35) PVD coated grade. Mainly used in machining steel and stainless steel small parts. It has excellent built-up edge resistance, good machining stability, can obtain good surface quality, and achieve longer tool life.
AP100S M15(M05-M25) PVD coated grade, recommanded for finish turning due to its high hardness and resistance to plastic deformation.
