Manufactured to TPMT style geometry, this insert features a 60-degree triangular shape with a neutral hand orientation, making it suitable for both external and internal turning operations. The HC335 grade carbide substrate is CVD-coated with a three-layer TiC, TiCN, and TiN coating system, delivering wear resistance and thermal stability across a range of cutting conditions. With a 3\/8-inch inscribed circle and a 1\/32-inch corner radius, this insert is well suited for medium-duty finishing and semi-finishing passes on steel and stainless workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in turning applications involving primary workpiece material grade P (carbon and alloy steels) and secondary material grade M (stainless steels), corresponding to material grades C5 and C6. It is held in place by a screw-clamp toolholder and is compatible with TPMT-style insert pockets. The T-style chip breaker geometry assists in controlling chip flow during continuous turning passes. Typical users include CNC machinists, tool and die shops, and production turning operations in industrial manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHC335 grade solid carbide substrate with CVD-applied TiC, TiCN, and TiN multilayer coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eTPMT insert style with 60-degree triangular shape and neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003e1\/32-inch corner radius suited for semi-finishing and finishing operations\u003c\/li\u003e\n  \u003cli\u003eT-style chip breaker geometry for controlled chip evacuation in steel turning\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp holding method for positive insert seating and repeatability\u003c\/li\u003e\n  \u003cli\u003eRated for P-grade (steel) primary and M-grade (stainless) secondary workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TPMT-style screw-clamp turning toolholders accepting a 3\/8-inch inscribed circle insert with clearance code P and tolerance code M.
