Internal boring operations naturally suffer from tight clearances and a higher tendency to chatter; the -SU layout drastically cuts down radial forces to stop vibration before it starts, while rolling chips tighter so they clear out easily via the boring bar flute.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px;\"\u003e\n\u003cp style=\"margin: 0 0 5px 0; font-weight: bold; color: #47479f;\"\u003eQ: Chips are bird-nesting inside my blind bore when using this insert. What is the cause?\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding-left: 15px; font-size: 13px;\"\u003eA: Bird-nesting occurs if the depth of cut (ap) drops below the chipbreaker's operational activation floor (less than 0.15mm), causing the material to smear rather than fracture. Slightly increase your depth of cut or feed rate to force the stringy stainless chip against the positive step wall of the -SU profile, or adjust your coolant nozzle to flush directly into the bore.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px;\"\u003e\n\u003cp style=\"margin: 0 0 5px 0; font-weight: bold; color: #47479f;\"\u003eQ: Can the AC630M grade handle continuous cutting in hardened stainless or duplex materials?\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding-left: 15px; font-size: 13px;\"\u003eA: Absolutely.
