Nose Flank Sub breaker GM breaker Sub breaker of the main and chip breaker. Excellent in notching resistance for light cutting to medium cutting. Nose breaker for medium cutting Excellent resistance to plastic deformation As a result of obtaining the optimum land geometry by simulation analysis technology, the plastic deformation of the insert corner was controlled and achieved long tool life. breaker for rough cutting Excellent fracture resistance By optimizing the land angle and honing geometry, high cutting edge stability is achieved during interrupted machining. 6 Nose 10 Flank 3 Nose 6 Flank Flank 15 Multi-Assist breaker MA breaker Suitable for medium cutting range Nose Flank 6 2

The protruding chipbreaker provides an ideal range of chip control. 5 Positive Insert 18 8 Nose Flank breaker for medium cutting First recommendation for medium cutting of stainless steel The flat land enables a good balance of wear and fracture resistance. The wide pocket reduces vibration and chip jamming and also prevents increases in cutting resistance even at large depths of cut. 5 Positive Insert Nose 0.1 Flank 0.1 3
