If your application involves stable, high-speed continuous turning, the harder AC820P or AC8025P grades will provide better wear economy. Switch to AC830P specifically when edge chipping or premature breakage occurs.\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: How does the LU chipbreaker handle chip control at lower depths of cut?\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding-left: 15px; font-size: 13px;\"\u003eA: The LU chipbreaker features a wider land design configured specifically to reduce cutting resistance under high-feed, high-depth loads ($a_p \\ge 1.5\\text{mm}$). If you drop the depth of cut below $1.0\\text{mm}$, the chip may miss the breaker deflector wall, leading to long ribbon strings.
