It carries a multilayer PVD coating of TiN, TiCN, and TiN applied over a solid carbide substrate in manufacturer grade KC725M. The insert is square in shape with a 90-degree included angle, a neutral hand orientation, and a GN chip breaker geometry. At 0.1875 inches thick with a 0.5 inch inscribed circle and a 1.00 mm (0.0394 inch) corner radius, it is sized for standard indexable milling toolholders that accept the SEKN 43 insert size. Holding is by screw clamp. Licensed HVAC techs and machinists in metalworking and tool-and-die environments install and index these inserts during routine cutting-edge replacement.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for milling operations on steel, stainless steel, superalloys, and titanium — ISO material groups P, M, and S. The KC725M grade and PVD multilayer coating are matched to applications where controlled heat and edge toughness matter, such as face milling, shoulder milling, and general-purpose milling passes on difficult-to-machine alloys. The neutral rake angle of 0 degrees and 20-degree relief angle make it suitable for a range of cut conditions from light finishing to moderate roughing on the listed workpiece materials. It is sold in a minimum order quantity of 5 units, with each package containing 1 insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePVD multilayer coating: TiN outer, TiCN mid, TiN base — improves wear resistance and edge stability on steel and superalloys\u003c\/li\u003e\n  \u003cli\u003eSolid carbide substrate in KC725M grade rated for material groups C5, C6, and C7\u003c\/li\u003e\n  \u003cli\u003eGN chip breaker geometry for effective chip control across P, M, and S workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle and neutral hand — compatible with standard SEKN screw-clamp toolholders\u003c\/li\u003e\n  \u003cli\u003e1.00 mm corner radius balances surface finish quality with edge strength\u003c\/li\u003e\n  \u003cli\u003e0-degree rake angle and 20-degree relief angle support versatile milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use indexable insert for SEKN-series screw-clamp milling toolholders accepting insert size code 43 with a 0.5 inch inscribed circle.

Always de-energize and lock out the machine spindle before handling inserts. Inspect the insert pocket seat and clamp screw for damage or debris before seating a new insert. Do not overtighten the clamping screw beyond the toolholder manufacturer specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SEKN1204AFSNGN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SEKN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN, TiCN, TiN (PVD multilayer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSubstrate Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (0.5000 to 0.5100 inches range)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (range: 0.1850 to 0.2000 inches)\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\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: GN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P, M, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0181 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\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: 1159625\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731004948786,"sku":"1159625","price":243.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ecf743b1c412158b11baa4b9d5caf514.jpg?v=1788725747","url":"https:\/\/voomisupply.com\/products\/kennametal-1159625-sekn1204afsngn-kc725m-milling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
