AC6030M General Purpose
Grade for general stainless steel turning, 1st choice, by the improvement of strength of coating layer with the CVD coating Absotech®and adhesion resistance by smooth edge treatment, achieves much less damage of cutting edge, stable and long tool life.
Absotech ®
CVD Coating
Drastically improved chipping resistance and adhesion resistance thanks to stress control techniques and surface smoothness treatment (patented technology).

AC6040M
Interrupted Cut
Grade for interrupted cutting of stainless steel, the PVD coating Absotech®, features a composition of TiAlSiN multi-layer structure and exclusive carbide substrate with high peeling and chipping resistance. The result is improved stability of tool life even in unstable cutting.
Absotech ®
PVD Coating
Improves the stability of the cutting edge by succeeding our unique ultra-multi-layered coating structure, which is applied to Super ZX Coating, and by employing highly heat-resistant coating of new composition, as well as improving the adhesion strength between carbide substrate and coating
TiAlSiN -based, ultra-multi -layered coating structure
