The insert features a CVD-applied TiCN and Al2O3 multilayer coating that provides wear resistance and thermal stability during continuous and interrupted cuts. With a 60-degree triangular shape, a 0.5-inch inscribed circle, and a 1\/64-inch corner radius, it is suited for medium to finishing passes. Holding method is clamp and pin, and the positive rake geometry reduces cutting forces on the workpiece. Licensed machinists and CNC setup technicians install this insert in ISO-standard toolholders.\u003c\/p\u003e\n\u003cp\u003eThe ISCAR 5550468 is intended for turning ferrous and stainless steel workpiece materials, corresponding to ISO material groups P and M. It is a fit for production turning environments where consistent surface finish and tool life are priorities. The TF chip breaker geometry handles chip control across a range of feed rates and depths of cut up to 3.50 mm (0.1378 inches). The insert is part of the ISCAR Isoturn series and conforms to ISO 13399 cutting tool data standards, making it compatible with digital tool management systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTNMG431TF geometry with 60-degree included angle and positive rake for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eIC8250 grade with CVD TiCN and Al2O3 multilayer coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eTF chip breaker optimized for medium to finishing depths of cut up to 3.50 mm\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for secure seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 cutting tool data standard\u003c\/li\u003e\n  \u003cli\u003ePrimary workpiece material suitability: ISO groups P (steel) and M (stainless steel)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TNMG-style toolholders with clamp and pin insert holding.
