BNC2020
■ Features
● BNC2010
· Grade for high-precision finishing requiring good surface roughness and dimensional tolerance. Ideal for high-precision machining thanks to excellent wear resistance. · Further maintains excellent surface roughness. Maintains excellent surface roughness thanks to coating with high notch wear resistance and CBN substrate.
● BNC2020 · General-purpose grade suitable for typical hardened steel machining applications. Achieves further stability in machining of a wide range of hardened steel components.
· Achieves long tool life thanks to highly wear-resistant, highly adhesive coating and tough CBN substrate. Achieves long, stable tool life even in high-efficiency and interrupted machining.
