CBN - SUMIBORON Break Master FV / LV / SV
■ Features ● One-use CBN - SUMIBORON insert with chipbreaker. SV type is ideal for carburized layer removal, while FV and LV types are ideal for hardened steel machining. ● Chipbreaker incorporated on the CBN cutting edge to maintain chip control capabilities throughout the machining process. ● Unique chipbreaker design can be applied to both hardened and non-hardened parts with effective chip control. ● SV lineup includes Coated CBN - SUMIBORON BNC2010/ BNC160 for good wear resistance and BNC2020/BNC200, which enables high efficiency machining. ● FV and LV lineup include Coated CBN - SUMIBORON BNC2020/BNC200 for general purpose, BNC2010/BNC160 for good wear resistance and CBN - SUMIBORON BN2000 also for general purpose.
