It features a multilayer CVD coating of TiCN and Al2O3 that provides wear resistance and thermal protection at the cutting zone. The triangle insert shape (60-degree included angle) delivers six usable cutting edges per insert, extending tool life per unit. With an inscribed circle of 0.5 inches and a corner radius of 0.0156 inches, this insert is suited to moderate stock removal and finishing passes on steel and cast iron. Licensed machinists and CNC operators install this insert as part of the KENLOC tooling system.\u003c\/p\u003e\u003cp\u003eThis insert is used in turning centers and manual lathes performing operations on steel and cast iron workpieces. Its neutral hand orientation makes it compatible with both right- and left-hand holders depending on setup. The MN chip breaker geometry is intended for a broad range of depths of cut up to 0.2884 inches, covering roughing to semi-finishing applications in production and job-shop environments. The chamfered and honed cutting edge style reduces chipping risk on interrupted or variable-feed cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer CVD coating: TiCN and Al2O3 for wear and crater resistance\u003c\/li\u003e\n\u003cli\u003eTriangle insert shape with 60-degree included angle and 6 cutting edges\u003c\/li\u003e\n\u003cli\u003eMN chip breaker geometry for turning, facing, and boring versatility\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut: 0.2884 inches\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge for improved edge stability\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards; ISO code TNMG220404MN\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC clamping and pin-style toolholders accepting TNMG-style inserts.

Power down and lock out the machine spindle before seating or replacing inserts. Ensure the insert pocket and seating surface are clean and free of chips before clamping. Use the correct torque for the clamp screw per the toolholder manufacturer specification — do not over-torque, as this can fracture the insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TNMG431MN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TNMG220404MN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP25C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.8661 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2884 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN \/ Al2O3 (Multilayer CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7026447\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748805837106,"sku":"7026447","price":162.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/357289045f06a6970c6b21793f90816c.jpg?v=1788898699","url":"https:\/\/voomisupply.com\/products\/kennametal-7026447-tnmg431mn-kcp25c-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
