It features a multilayer PVD coating of TiCN, Al2O3, and TiN applied over a solid carbide substrate, making it well suited for demanding metal-cutting operations. The insert has a 60-degree triangular shape with a 0.5-inch inscribed circle, a 1\/64-inch (0.0156-inch) corner radius, and an insert length of 22 mm (0.866 inches). The PP chip breaker geometry promotes positive rake cutting action. Licensed machinists, CNC lathe operators, and tool-and-die shops typically specify and install this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for turning applications on stainless steel and steel workpieces, corresponding to ISO material codes M and P. It belongs to the ISCAR Isoturn series and is suited for both roughing and finishing passes within its rated maximum depth of cut of 3.5 mm (0.1378 inches). The TNMG-style seat and dual holding method — clamp and pin — make it compatible with standard TNMG toolholders used in CNC and manual turning centers across production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC8250 grade solid carbide substrate with PVD-applied TiCN, Al2O3, and TiN multilayer coating for extended tool life on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTNMG431PP designation — 60-degree triangle, 0.5-inch inscribed circle, 3\/16-inch thickness, PP chip breaker\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch corner radius (0.0156 inches) for general-purpose turning with balanced edge strength\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut 3.5 mm (0.1378 inches) — suitable for medium material removal rates\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry reduces cutting forces and heat buildup on workpiece\u003c\/li\u003e\n  \u003cli\u003eDual holding method (clamp and pin) with TNMG seating for rigid, repeatable insert positioning\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard TNMG-style insert toolholders that accept a 60-degree triangular insert with a 0.5-inch inscribed circle and 3\/16-inch thickness.

Ensure the insert pocket and clamping seat are clean and free of chips before seating the insert. Tighten the clamping screw to the toolholder manufacturer's specified torque to avoid insert rocking or premature edge failure. Inspect the chip breaker and cutting edge condition at each tool change interval.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC8250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (PVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 22 mm (0.866 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\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.5 mm (0.1378 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel (ISO M, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.298 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5550466\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737081020722,"sku":"5550466","price":286.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a66515d5613a6b4b28144f1205ee23f8.jpg?v=1788784010","url":"https:\/\/voomisupply.com\/products\/iscar-5550466-tnmg431pp-ic8250-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
