CBN cutting insert BNC2115

for hardened steelcoated

BNC2105, BNC2115, BNC2125 and BNC2135 have been added to our coated SUMIBORON series and are our first recommendations for hardened steel machining, for even higher efficiency machining. It's the pinnacle of high accuracy and high efficiency cutting. BNC2105 for high-speed Machining BNC2115 for high-accuracy machining BNC2125 first recommendation for hardened steel machining BNC2135 for Heavy Interrupted Machining for a stable and long tool life under highspeed machining New coating technology and modified CBN substrate, with excellent heat resistance 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 tough CBN substrate. First recommendation for hardened steel machining. Superb wear and fracture resistance. Achieves long, stable tool life even in high-efficiency and interrupted machining. Along with a tough CBN substrate, the coating combines wear resistance and toughness to realise stable machining Achieves long and stable tool life in heavy interrupted cutting of hardened steel Utilising a highly fracture-resistant coating and a high-strength substrate to achieve long and stable tool life in interrupted machining.
