Recommended Application Features Application Range Movie The Pinnacle of High Accuracy/High-efficiency Cutting The definitive grade in high-accuracy machining Realises long tool life with excellent surface roughness and stable machining. Further maintains excellent surface roughness Maintains excellent surface roughness thanks to a coating with high notch wear resistance and toughCBN substrate. First recommendation for hardened steel machining Superb wear and fracture resistance. Along with a tough CBN substrate, the coating combines wear resistance and toughness to realise stabler machining Achieves long, stable tool life even in high-efficiency and interrupted machining. Grade for high-precision finishing requiring good surface roughness and finished surface accuracy Grade ideal for high-precision machining, with highly wear-resistant CBN substrate and coating. General-purpose grade suitable for typical hardened steel machining applications Achieves further stability in machining of a wide range of hardened steel components. Long, stable tool life in interrupted cutting Achieves long, stable tool life even in workpieces requiring both continuous and interrupted cutting. Features Application Range Movie
