It features a triangular insert shape with a 60-degree included angle, a 1\/4-inch inscribed circle, and a 1\/64-inch corner radius. The insert is coated with a TiCN, Al2O3, and Cr multilayer stack applied via CVD under SECO's Duratomic coating classification, producing a wear-resistant surface suited to steel and cast iron cutting. Neutral hand orientation and a positive rake geometry allow use across back turning, boring, facing, and straight turning operations. The F1 chip breaker is configured for sharp-edge cutting and is aimed at machinist and toolroom applications requiring consistent chip control.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use on ferrous workpiece materials, with a primary designation for steel (ISO P) and secondary suitability for cast iron and hard materials (ISO K and H). It fits TCMT-style toolholders using screw clamping and is appropriate for light-to-medium roughing and finishing passes. With a maximum depth of cut of 0.3937 inches, it covers a broad range of common turning scenarios in production and job-shop environments. Machinists and CNC operators working in steel fabrication, automotive, or general machining will find this insert well suited to standard turning applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiCN, Al2O3, and Cr CVD Duratomic coating for extended tool life on steel\u003c\/li\u003e\n  \u003cli\u003eTriangular insert shape (60-degree included angle) with 3 usable cutting edges for cost efficiency\u003c\/li\u003e\n  \u003cli\u003eF1 chip breaker with sharp cutting edge style for reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry reduces cutting forces on workpiece and toolholder\u003c\/li\u003e\n  \u003cli\u003eScrew-clamped insert holding method for rigid, repeatable positioning\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: back turning, boring, facing, and turning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for TCMT-style screw-clamped toolholders accepting a 1\/4-inch inscribed circle triangular insert.
