BNC300 - Specialist for Heavily Interrupted Cutting and Difficult Conditions
The CBN cutting material grade BNC300 is specially designed for high-wear machining with interrupted cutting and difficult machining conditions.
It proves to be particularly tough and withstands even impact loads over long tool life. It can also handle combined hard turning with interrupted and continuous cutting in alternation without any problems. BNC300 grade inserts can be used to reliably turn hardened gears or serrations, for example.
