It features a multilayer CVD coating of TiN, TiCN, and Al2O3 TiN that provides wear resistance and thermal stability during continuous and interrupted cuts. The insert has a 3\/8-inch inscribed circle, a 0.0313-inch corner radius, a positive rake angle of 10 degrees, and a honed cutting edge style. The PS chip breaker geometry is engineered for reliable chip control across a broad range of cutting conditions. This insert is used by machinists and CNC turning specialists in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 6781066 is suited for turning, facing, and boring operations on steel, stainless steel, and cast iron workpieces. Its ISO material grade designations of P15 and P25 place it in the light-to-medium roughing range for ferrous materials. The insert conforms to both ANSI and ISO standards and carries the industry standard number TCMT 32.52 PS, making it straightforward to cross-reference against other TCMT-format inserts. It is appropriate for use in screw-clamp toolholders designed for the TCMT insert style.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating (TiN \/ TiCN \/ Al2O3 \/ TiN) for extended tool life on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eT9225 manufacturer grade rated for P15-P25 steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003ePS chip breaker geometry supports turning, facing, and boring with positive rake action\u003c\/li\u003e\n  \u003cli\u003e3 cutting edges per insert with neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces micro-chipping at the edge line\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; cross-references to TCMT 32.52 PS industry number\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TCMT-style screw-clamp toolholders accepting a 3\/8-inch inscribed circle triangular insert with a 7-degree relief angle (clearance code C, tolerance code M).
