It features a square shape with a 90-degree included angle, four cutting edges, and a neutral rake and hand orientation. The insert is PVD-coated with a TiAlN and TiN multilayer finish, grade F40M, fine-grain carbide substrate. A T-land cutting edge style and 20-degree relief angle help manage entry forces and edge stability during milling operations. Maximum depth of cut is 0.3465 inches. Licensed machinists and CNC mill operators install this insert class into compatible indexable milling cutter bodies.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Primary workpiece material codes are P, K, and S. Secondary material codes are K and N. It is held in the cutter body by a wedge clamp mechanism. The M14 chip breaker geometry is designed to control chip formation across a range of feed and depth conditions common in production and job-shop milling environments, both roughing and semi-finishing passes on ferrous and exotic alloy components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide fine-grain substrate, manufacturer grade F40M\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiAlN and TiN dual-layer coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape, 90-degree included angle, 4 indexable cutting edges\u003c\/li\u003e\n  \u003cli\u003eNeutral rake and neutral hand — compatible with standard right-hand cutter bodies\u003c\/li\u003e\n  \u003cli\u003eT-land cutting edge style with 20-degree relief angle\u003c\/li\u003e\n  \u003cli\u003eM14 chip breaker geometry for steel, cast iron, superalloys, and titanium applications\u003c\/li\u003e\n  \u003cli\u003eWedge clamp insert holding method for secure seating under interrupted and continuous cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cutter series R220.13-12 milling bodies.

Always power down and lock out the spindle before indexing or replacing inserts. Use the correct torque driver specified by the cutter body manufacturer for the wedge clamp screw — do not over-torque or substitute fasteners. Inspect the pocket seating surface for chips or debris before seating a fresh insert, as contamination will cause runout and premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: F40M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide, Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and TiN\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\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1252 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0394 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3465 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1203\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Wedge Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R220.13-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SEKN1203AFTN-M14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SEKN1203AFTN-M14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74078899\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558706020658,"sku":"74078899","price":296.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e8e94d5e7e033bdd1077b710a8856b9.jpg?v=1786418512","url":"https:\/\/voomisupply.com\/products\/seco-74078899-sekn1203aftn-m14-milling-insert-f40m-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
