It features a square shape with a neutral hand orientation and a 90-degree included angle, making it suited for a wide range of milling operations. The insert carries a multilayer PVD coating sequence of TiN, TiCN, and TiN, which improves wear resistance and thermal stability at the cutting edge. The 20-degree relief angle and LN chip breaker geometry are designed to manage chip flow and reduce cutting forces. Thickness runs 0.1875 inches with a 1.00 mm corner radius. Licensed HVAC, machining, and tooling professionals install and service these inserts in production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis insert is designed for milling applications in steel, stainless steel, superalloys, and titanium, corresponding to ISO material groups P, M, and S. The KC725M grade is positioned for interrupted and continuous cuts across these demanding workpiece materials. It is held in place by a screw-clamping method and fits toolholders designed for the SEKN insert series. Typical use cases include face milling, shoulder milling, and general-purpose milling on CNC machining centers in both job shop and production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with multilayer PVD coating: TiN, TiCN, TiN for extended tool life\u003c\/li\u003e\n\u003cli\u003eSquare insert shape with 90-degree included angle and neutral hand orientation\u003c\/li\u003e\n\u003cli\u003e1.00 mm corner radius minimizes surface stress at the cutting edge\u003c\/li\u003e\n\u003cli\u003e20-degree relief angle reduces rubbing and heat buildup on the flank face\u003c\/li\u003e\n\u003cli\u003eLN chip breaker geometry promotes controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew-holding method ensures secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw-clamp replacement insert for toolholders accepting the SEKN insert series.

Use the manufacturer-specified torque driver for the clamping screw to ensure proper seating without over-torquing. Inspect the pocket seat and clamping screw for wear or debris before installing a new insert. Do not mix insert grades or geometries within a multi-insert cutter body unless confirmed compatible by the toolholder manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Designation\u003c\/strong\u003e: SEKN1204AFENLN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: TiN, TiCN, TiN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.00 mm (0.0394 inches)\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\u003eInscribed Circle\u003c\/strong\u003e: 0.6252 inches (5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003eWeight\u003c\/strong\u003e: 0.0441 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\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: 1180955\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750565937458,"sku":"1180955","price":251.12,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20b3f0639bf9e7fe7f948adeb17cb9a2.jpg?v=1788916758","url":"https:\/\/voomisupply.com\/products\/kennametal-1180955-sekn1204afenln-kc725m-milling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
