It is manufactured from carbide substrate and features a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr for extended wear resistance and thermal stability. The insert carries a TP2501 manufacturer grade and an MF2 chip breaker geometry optimized for light-to-medium finishing and semi-finishing passes. With 6 cutting edges per insert, a 0.5-inch inscribed circle, and a 0.0157-inch corner radius, it delivers consistent, repeatable results across high-volume production environments. CNC machinists and tool-and-die professionals specify this insert for its balance of edge security and surface finish performance.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for primary use on steel (ISO material code P) and is also suitable for stainless steel (M) and cast iron (K) applications. The MF2 chip breaker geometry supports boring, facing, and turning operations at light-to-moderate depths of cut up to 0.3346 inches. Its neutral hand orientation makes it adaptable to both left- and right-hand toolholders. The insert holds to ISO tolerance code M and clearance code N, fitting standard WNMG-style toolholders with clamp, pin, or lever-lock retention systems. Applicable material grades include P10, P20, P30, and P35.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for high-temperature wear resistance\u003c\/li\u003e\n  \u003cli\u003eMF2 chip breaker geometry for finishing and semi-finishing on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e6 indexable cutting edges per insert for maximum cost efficiency\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard WNMG left- and right-hand toolholders\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for edge strength and reduced chipping risk\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in WNMG-style toolholders accepting a 0.5-inch inscribed circle insert with an 0.2028-inch hole diameter.

Power down and de-energize the machine before indexing or replacing inserts. Use the appropriate torque wrench per toolholder manufacturer specifications when securing the clamping screw or lever-lock mechanism. Inspect the toolholder seat and shim for damage before seating a new insert to ensure proper support and prevent 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: WNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: WNMG-MF2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP2501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P10, P20, P30, P35\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: Trigon (80 degrees included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: 0.0157 inches (1\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.685 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3346 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (CVD Duratomic)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: WNMG080404-MF2\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 02959841\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559430521138,"sku":"02959841","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3073e69dbad5d84c1cbc158b7fd3a32f_c68a169f-d679-4765-9566-d20e80ebfc78.jpg?v=1786432273","url":"https:\/\/voomisupply.com\/products\/seco-02959841-wnmg431-mf2-turning-insert-carbide-cvd","provider":"Voomi Supply","version":"1.0","type":"link"}
