The AC630M PVD grade features a much thinner, high-adhesion coating that maintains a sharp edge profile, preventing boundary notch wear and built-up edge formation.\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: Does the -SU chipbreaker manage high-depth roughing cuts efficiently?\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding-left: 15px; font-size: 13px;\"\u003eA: No. The -SU geometry is specifically engineered for finishing to medium profiling applications, with a maximum depth of cut (DOC) up to 3.0mm.
