Features
Highly wear-resistant grade for high-speed machining Excellent wear resistant coating and CBN substrate, achieves stable and long tool life in high-speed machining. The ultimate in high-precision machining of hardened steel Utilizing a thick coating with exceptional notch wear resistance and a tough CBN substrate to achieve stable and excellent surface finish. First recommendation for hardened steel machining Combination of a tough CBN substrate and a thick coating that has a balance of wear resistance and toughness, to achieve stable machining in a wide range of applications. Achieves long, stable tool life in machining with heavy interrupted cutting Achieves long, stable tool life on work pieces with both continuous and interrupted cutting High-precision grade for low- to medium-speed machining Excellent wear resistant CBN substrate and coating layer, for high-precision machining that requires surface roughness and surface finish accuracy. General-purpose grade for low- to medium-speed machining Utilizing an exceptionally high wear resistant coating and a tough CBN substrate. Excellent machining stability in low-rigidity situations and high-feed cutting
