It features a CVD-applied multilayer coating of Al2O3, TiCN, and TiN over a carbide substrate, providing wear resistance and thermal stability at the cutting edge. The insert has an 80-degree trigon shape (W), a 3\/8-inch inscribed circle, and a 0.0156-inch corner radius. The WF chip breaker geometry is suited for finishing to medium cutting operations. A licensed machinist or CNC setup technician installs and indexes this insert as part of routine tooling maintenance.\u003c\/p\u003e\u003cp\u003eThis insert is intended for machining steel (ISO material code P) as the primary workpiece material, with cast iron (ISO material code K) as a secondary application. It is well suited for finishing cuts where consistent chip control and surface finish are required. The neutral hand orientation allows use in both left- and right-hand toolholders that accept WNMG-style inserts. The T-Max P series is a common platform in production turning environments, both in job shop and high-volume manufacturing settings. Each package contains one insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: Al2O3, TiCN, and TiN for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eWF chip breaker geometry optimized for steel finishing and medium turning\u003c\/li\u003e\n\u003cli\u003eTrigon (80-degree) insert shape with 6 usable cutting edges\u003c\/li\u003e\n\u003cli\u003e0.0156-inch corner radius for controlled surface finish\u003c\/li\u003e\n\u003cli\u003eNeutral hand insert compatible with clamp and screw holding methods\u003c\/li\u003e\n\u003cli\u003eISO code WNMG 06 04 04-WF 4425 for cross-reference and toolholder matching\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders that accept WNMG-style inserts with clamp or screw holding methods, as specified in the T-Max P series platform.

Use the appropriate torque wrench and seating tools specified by the toolholder manufacturer when securing the insert with the clamp or screw holding method. Inspect the insert pocket and clamping hardware for wear or damage before seating a new insert. Do not exceed the cutting parameter ranges published in the tooling system documentation for this grade and geometry.\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\u003eISO Code\u003c\/strong\u003e: WNMG 06 04 04-WF 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (W)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Al2O3, TiCN, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.54 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.74 inches\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: 7861140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51752659845426,"sku":"7861140","price":37.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2558b5efd27b392b264838be7681e0f_6efb4e18-f491-4b07-8dfe-856017da4c45.jpg?v=1788929622","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7861140-wnmg331-wf-4425-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
