The insert features a TiAlN and AlCr2O3 PVD coating applied over a carbide substrate, delivering strong resistance to heat and wear. With an 80-degree trigon shape, a neutral hand orientation, and a 0.0156-inch corner radius, it is engineered for finish and semi-finish turning passes that require tight dimensional control. Machinists and CNC operators working with difficult materials rely on this insert for consistent edge performance across extended run times.\u003c\/p\u003e\n\u003cp\u003eThis insert is optimized for primary use on stainless steel workpieces and is also rated for secondary applications on superalloys and titanium — material families that demand high edge stability and coating integrity. The MF chip breaker geometry is suited to finishing cuts at moderate feed rates, producing manageable chips and controlled surface finishes. It is a direct-fit replacement insert for T-Max P compatible toolholders used in CNC turning centers and manual lathes in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWNMG431-MF geometry with 80-degree trigon shape and 6 usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eGrade 1115 carbide substrate with TiAlN and AlCr2O3 PVD dual-layer coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMF chip breaker optimized for finish and semi-finish turning on difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003e0-degree relief angle (clearance code N) with tolerance code M for consistent seating and repeatability\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert-holding method compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in T-Max P series toolholders accepting WNMG-style inserts with a 0.5-inch inscribed circle.

The machine spindle must be stopped and locked out before seating or indexing the insert. Ensure the insert pocket and clamp surfaces are clean and free of chips or debris before securing the insert to prevent seating errors that can cause premature edge failure. Follow the toolholder manufacturer torque and clamping guidelines for the specific clamp or pin style in use.\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\u003eGrade\u003c\/strong\u003e: 1115\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (80-degree included angle)\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: MF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3263 inches (8.29 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches (5.16 mm)\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\u003eCoating\u003c\/strong\u003e: TiAlN \/ AlCr2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: WNMG 08 04 04-MF 1115\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5756458\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51738683277618,"sku":"5756458","price":340.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a15110b62c5f2bdeaa03ffe0cf49d3c_4b2df9df-7f46-4479-bb88-34b0da4e34fb.jpg?v=1788802780","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5756458-wnmg431-mf-1115-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
