Leveraging Sumitomo's proprietary \u003cstrong\u003eAbsorb Coating Super PVD technology\u003c\/strong\u003e, this insert integrates a highly texturized, ultra-dense TiAlN (Titanium Aluminum Nitride) multi-layer matrix over a tough, chip-resistant carbide substrate. This advanced lattice acts as a superior thermal barrier, suppressing extreme friction heat, built-up edge (BUE), and notch wear during continuous medium roughing of stainless steel. Outfitted with the \u003cstrong\u003eGU general-purpose to medium-roughing chipbreaker geometry\u003c\/strong\u003e, its multi-stage variable rake face forces stubborn, gummy ductile metal chips into tight, uniform 6-shaped curls, eliminating catastrophic wrapping around the workpiece. Featuring a negative 60-degree triangular architecture, it provides 6 highly economical cutting edges engineered to drop total cycle times and maximize corporate metal removal rates (MRR).\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: 15px;\"\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: 15px;\"\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: 15px;\"\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: 15px;\"\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: 15px;\"\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: 15px;\"\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: 15px;\"\u003e12\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003e1.2mm 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: 15px;\"\u003eN\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003eNeutral Rake Direction\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: 15px;\"\u003eGU\u003c\/div\u003e\n\u003cdiv style=\"padding: 6px; font-size: 11px; color: #555555; font-weight: 500;\"\u003eGeneral Purpose \/ Medium Roughing\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- 2.
