It features a multilayer PVD coating of TiCN, Al2O3, and TiN applied over a solid carbide substrate, providing wear resistance and thermal stability during metal cutting. The insert has a 90-degree square shape with a 0.5-inch inscribed circle and a 1\/64-inch corner radius, making it suitable for general-purpose turning with moderate feed rates. Licensed machinists and CNC operators install this insert into compatible SNMG-style toolholders as a precision cutting edge component.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for use in the Isoturn series and is suited for turning steel and stainless steel workpiece materials, corresponding to ISO material codes P and M. The TF chip breaker geometry supports controlled chip evacuation across a range of cutting depths up to 0.1575 inches (4.00 mm). It is appropriate for both roughing and semi-finishing passes on ferrous materials in production and job-shop environments. The insert seats securely using clamp and pin holding methods, which are standard on most SNMG-compatible turning toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade IC8250 solid carbide with PVD-applied TiCN, Al2O3, and TiN multilayer coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eSNMG431TF geometry: 90-degree square insert with positive rake and TF chip breaker\u003c\/li\u003e\n  \u003cli\u003e0.5-inch inscribed circle and 3\/16-inch insert thickness for rigid seating in standard toolholders\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch corner radius suitable for moderate finishing and semi-roughing applications\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.1575 inches (4.00 mm) for controlled material removal\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin holding methods; ISO 13399 compliant geometry data\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SNMG-style turning toolholders that accept a 0.5-inch inscribed circle square insert with a 0.203-inch hole diameter and clamp or pin clamping.
