It incorporates a significantly tougher carbide core matrix than the AC6020M, making it much more robust against thermal cracking, variable mechanical shock, and scale crusts during mid-range general processing sequences.\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 GU chipbreaker address the work-hardening tendencies of stainless steel?\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding-left: 15px; font-size: 13px;\"\u003eA: The GU chipbreaker features a uniquely optimized positive rake geometry that creates a highly effective shearing action. By cleanly cutting rather than pushing the gummy material, it reduces the depth of the work-hardened layer on the workpiece surface, protecting subsequent cutting edges from accelerated notch wear.\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: What is the recommended coolant strategy when running this insert?\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding-left: 15px; font-size: 13px;\"\u003eA: High-pressure flood coolant targeted directly at the tool-workpiece interface is strongly advised for stainless steels.
