Utilizing Sumitomo's pioneering \u003cstrong\u003eACP300 PVD multi-layered coating technology\u003c\/strong\u003e, this grade combines a high-toughness carbide substrate with a smooth, highly dense nano-structured TiAlN coating layer. This specific composition provides exceptional thermal shock resistance, excellent resistance to chipping during interrupted cuts, and low friction coefficients that prevent built-up edge formation. Paired with the highly engineered \u003cstrong\u003e-G Type General-Purpose Chipbreaker\u003c\/strong\u003e geometry, this insert features a positive rake angle architecture that lowers cutting forces, ensures smooth chip evacuation, and maintains supreme edge integrity under aggressive feed rates.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- Section 2: Key Features --\u003e\n\u003cdiv style=\"margin-bottom: 35px;\"\u003e\n\u003ch2 style=\"color: #47479f; border-bottom: 2px solid #47479F; padding-bottom: 8px; font-size: 20px; font-weight: bold;\"\u003e2.
