It carries the ISO designation SEKT1404AEENGP2 and ANSI designation SEKT443AEEN7GP2, with a manufacturer grade of KC725M. The insert features a TiAlN coating applied via PVD process, a positive rake geometry, and a honed cutting edge style. At 0.5512 inches inscribed circle and 0.1875 inches thick, it delivers four usable cutting edges per insert with a 1.00 mm corner radius and a 20-degree relief angle. Screw-held and single-sided, it fits the KSSM cutter series and is suited to high-speed steel and superalloy milling operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for milling steel, stainless steel, superalloys, and titanium, covering material grades C5, C6, and C7 (ISO material codes P, M, and S). It is a neutral-hand insert appropriate for a range of face milling and shoulder milling setups in production machining environments. The GP2 chip breaker geometry supports controlled chip formation across these work materials. Machinists and CNC operators in aerospace, energy, and general manufacturing will find this insert applicable to medium-to-finishing cut conditions where tight tolerances and surface finish consistency are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eISO code SEKT1404AEENGP2 and ANSI code SEKT443AEEN7GP2 for direct cross-reference\u003c\/li\u003e\n  \u003cli\u003eKC725M grade with TiAlN PVD coating for heat resistance in steel and superalloy cuts\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert with neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eGP2 chip breaker for controlled chip evacuation across P, M, and S material groups\u003c\/li\u003e\n  \u003cli\u003ePositive rake and 20-degree relief angle reduce cutting forces on the workpiece\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style promotes edge stability and reduces microchipping\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with the KSSM cutter series.

Use the appropriate torque wrench and insert screw specified by the cutter body manufacturer when securing the screw-held insert. Inspect the cutter pocket seating surface for wear or debris before installing a new insert. Follow the cutter body manufacturer guidelines for recommended cutting parameters when using KC725M grade in the applicable material groups.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SEKT1404AEENGP2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SEKT443AEEN7GP2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SEKT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5512 inches (14.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0394 inches (1.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GP2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5512 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (0.17 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 443\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: KSSM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6, C7\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: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 2390257\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729690460466,"sku":"2390257","price":192.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3df60009b33262634b98274faab6c8f.jpg?v=1788707859","url":"https:\/\/voomisupply.com\/products\/kennametal-2390257-milling-insert-kc725m-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
