It features a trigon (80-degree included angle) insert shape with a solid carbide substrate and a CVD-applied multilayer coating of TiCN, Al2O3, and TiN. With 6 cutting edges, a 0.5000-inch inscribed circle, and a 1\/64-inch (0.0156-inch) corner radius, this insert is sized for medium to light finishing passes. The MF chip breaker geometry is optimized for stainless steel workpiece materials, controlling chip flow and reducing built-up edge during continuous cuts. Machinists and CNC operators working with ISO material group M applications will find this insert well matched to their tooling systems.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning operations on stainless steel and similar ISO M-class workpiece materials. It fits toolholders designed for WNMG-style inserts and is held in place using a clamp-and-pin method. The T-Max P series designation indicates compatibility with SANDVIK COROMANT T-Max P toolholder platforms used widely in production and job-shop turning environments. The neutral hand orientation makes it suitable for both external and select internal turning applications depending on holder geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003eMF chip breaker geometry optimized for stainless steel (ISO M) turning\u003c\/li\u003e\n\u003cli\u003e6 indexable cutting edges per insert for extended tooling economy\u003c\/li\u003e\n\u003cli\u003eClamp and pin insert holding method for secure seating in T-Max P toolholders\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for flexible toolholder pairing\u003c\/li\u003e\n\u003cli\u003e80-degree trigon shape (WNMG) with 0-degree relief angle (clearance code N)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in SANDVIK COROMANT T-Max P series toolholders accepting WNMG-style inserts with a clamp-and-pin holding method.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the clamping screw to the correct torque range per that holder's documentation. Inspect the toolholder pocket and locating pin for wear or debris before seating a new insert to ensure proper edge positioning and prevent premature failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\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\u003eChip Breaker\u003c\/strong\u003e: MF\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: 0.5000 inches (12.70 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\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\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 (Clearance Code N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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 and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: WNMG 08 04 04-MF 2025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5756466\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51748577542450,"sku":"5756466","price":332.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6b9e9f611ad40b3adc9a191cc0363bc_157f2d94-745c-4b1c-be08-33189169b124.jpg?v=1788895354","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5756466-turning-insert-wnmg431-mf-2025","provider":"Voomi Supply","version":"1.0","type":"link"}
