Designed for the highly demanding ISO P15-P30 application range, this double-sided triangular insert is powered by Sumitomo's breakthrough \u003cstrong\u003eAC820P Absotech technology\u003c\/strong\u003e. By depositing a dense, highly textured alumina (Al2O3) and titanium carbonitride (TiCN) crystalline layer via chemical vapor deposition (CVD) over a specialized gradient-rich carbide substrate, this insert provides exceptional crater wear resistance and thermal stability under high-speed cutting conditions. The optimized \u003cstrong\u003eSX chipbreaker profile\u003c\/strong\u003e features a robust cutting edge land coupled with a progressive deflection wall, allowing it to easily break tough steel chips, lower cutting forces, and prevent chip nests during unstable depths of cut or medium-to-roughing cycles.\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;\"\u003eMedium-Rough Steel Breaker\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- 2.
