SUMIBORON SUMIBORON Insert With Chipbreaker p Hardened Steel Break Master N-FV /- LV /-SV Characteristics SUMIBORON one-use insert with chipbreaker. N-SV type is perfect for carburised layer removal while N-FV / N-LV types are best suited to finishing of hardened steel. Breaker included on the CBN edge, chipbreaking effect can be maintained throughout machining process. Unique breaker design can be applied to both hardened and non-hardened parts with effective chip control. SV type lineup now includes BNC2010 / BNC160 for good wear resistance, while SUMIBORON BNC2020 / BNC200 allows high efficiency machining. In addition to general purpose SUMIBORON BNC2020 / BNC200, the N-FV / N-LV type lineup includes BNC2010 / BNC160 for excellent wear resistance and general purpose uncoated SUMIBORON BN2000.
