 One-use Inserts With Chipbreaker  Break Master FV Type / LV Type / SV Type ■ Characteristics ● SUMIBORON one-use insert with chipbreaker. SV type is perfect for carburised layer removal while FV / 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 chipbreaker design can be applied to both hardened and non-hardened parts with effective chip control. ● The SV Type lineup includes both the BNC2010 / BNC160 for good wear resistance and the BNC2020 / BNC200 with Coated SUMIBORON, which enables high efficiency machining. ● The FV Type and LV Type lineups include the BNC2010/ BNC160 for good wear resistance, the general-purpose BN2000 with Uncoated SUMIBORON, and the general- purpose BNC2020/BNC200 with Coated SUMIBORON. ■ Application Range 0.7 Depth of Cut (mm) 0.5 SV Type 0.3 LV Type 0.1 FV Type 0 0.1 0.2 0.3 Feed Rate (mm/rev) * For hardened parts (above 50HRC), please use less than 0.5mm depth of cut. ■ Application Example External Caburized Layer Removal Break Master-SV Type Finishing of Hardened Steel Break Master-FV Type L SUMIBORON Tool life=200pcs Tool life=300pcs BNC200 (no breaker) BNC200 (no breaker) · No constant stoppages or incorrect part dimension problems and the chips are small. · Double the tool life of competitor's CBN · Improved chip control during boring.
