Engineered for the demanding ISO P30-P40 application spectrum, this double-sided triangular insert is powered by Sumitomo’s breakthrough \u003cstrong\u003eAC830P Absotech Platinum CVD coating technology\u003c\/strong\u003e. By depositing an ultra-thick, highly textured α-alumina (Al2O3) and titanium carbonitride (TiCN) crystalline matrix over a high-toughness, deformation-resistant gradient carbide substrate, this insert achieves industry-leading resistance to thermal cracking and mechanical shock. The advanced \u003cstrong\u003eSX chipbreaker profile\u003c\/strong\u003e is specifically tailored with a widened, reinforced land and an aggressive deflection wall, allowing it to easily manage unstable depths of cut, break tough steel skins, and maintain exceptional process security under severe impact conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- ISO CODING SYSTEM VISUAL BOX MATRIX --\u003e\n\u003ch3 style=\"font-size: 15px; color: #333333; margin: 20px 0 10px 0; font-weight: bold;\"\u003eStrict ISO \/ ANSI Cutting Tool Standard Alphanumeric Decoding Matrix\u003c\/h3\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; gap: 6px; margin-bottom: 30px;\"\u003e\n\u003cdiv style=\"flex: 1; min-width: 90px; border: 1px solid #47479F; border-radius: 4px; text-align: center; background: #ffffff; box-shadow: 0 1px 3px rgba(0,0,0,0.05);\"\u003e\n\u003cdiv style=\"background: #47479F; color: #ffffff; font-weight: bold; padding: 6px; font-size: 14px;\"\u003eT\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003eTriangular Shape (60°)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 90px; border: 1px solid #47479F; border-radius: 4px; text-align: center; background: #ffffff; box-shadow: 0 1px 3px rgba(0,0,0,0.05);\"\u003e\n\u003cdiv style=\"background: #47479F; color: #ffffff; font-weight: bold; padding: 6px; font-size: 14px;\"\u003eN\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003e0° Negative Clearance\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 90px; border: 1px solid #47479F; border-radius: 4px; text-align: center; background: #ffffff; box-shadow: 0 1px 3px rgba(0,0,0,0.05);\"\u003e\n\u003cdiv style=\"background: #47479F; color: #ffffff; font-weight: bold; padding: 6px; font-size: 14px;\"\u003eM\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003ePrecision Tolerances\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 90px; border: 1px solid #47479F; border-radius: 4px; text-align: center; background: #ffffff; box-shadow: 0 1px 3px rgba(0,0,0,0.05);\"\u003e\n\u003cdiv style=\"background: #47479F; color: #ffffff; font-weight: bold; padding: 6px; font-size: 14px;\"\u003eG\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003eCylindrical Center Hole\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 90px; border: 1px solid #47479F; border-radius: 4px; text-align: center; background: #ffffff; box-shadow: 0 1px 3px rgba(0,0,0,0.05);\"\u003e\n\u003cdiv style=\"background: #47479F; color: #ffffff; font-weight: bold; padding: 6px; font-size: 14px;\"\u003e16\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003e16.5mm Edge Length\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 90px; border: 1px solid #47479F; border-radius: 4px; text-align: center; background: #ffffff; box-shadow: 0 1px 3px rgba(0,0,0,0.05);\"\u003e\n\u003cdiv style=\"background: #47479F; color: #ffffff; font-weight: bold; padding: 6px; font-size: 14px;\"\u003e04\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003e4.76mm Thickness\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 90px; border: 1px solid #47479F; border-radius: 4px; text-align: center; background: #ffffff; box-shadow: 0 1px 3px rgba(0,0,0,0.05);\"\u003e\n\u003cdiv style=\"background: #47479F; color: #ffffff; font-weight: bold; padding: 6px; font-size: 14px;\"\u003e08\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003e0.8mm Nose Radius\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 90px; border: 1px solid #47479F; border-radius: 4px; text-align: center; background: #ffffff; box-shadow: 0 1px 3px rgba(0,0,0,0.05);\"\u003e\n\u003cdiv style=\"background: #47479F; color: #ffffff; font-weight: bold; padding: 6px; font-size: 14px;\"\u003eN\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003eNeutral Orientation\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 90px; border: 1px solid #47479F; border-radius: 4px; text-align: center; background: #ffffff; box-shadow: 0 1px 3px rgba(0,0,0,0.05);\"\u003e\n\u003cdiv style=\"background: #47479F; color: #ffffff; font-weight: bold; padding: 6px; font-size: 14px;\"\u003eSX\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003eInterrupted Steel Roughing\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- 2.
