Part of the CoroThread 266 series, it features a TiCrAlN\/TiN PVD coating that improves wear resistance and tool life in ferrous and abrasive materials. The insert produces a 60-degree included angle thread profile at 10 threads per inch, making it a direct match for standard UN external threading applications. It is right-hand oriented with a single tooth per side and an A-style chipbreaker. This insert is installed by machinists and toolroom technicians using compatible CoroThread 266 toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external UN threading on CNC lathes and turning centers in both production and job-shop environments. The 266 insert style and size code 16 designate its seating geometry and clamping interface. With a 3\/8-inch inscribed circle and 5\/32-inch thickness, it fits standard laydown threading insert pockets designed for the CoroThread 266 platform. Typical applications include threading of steel, alloy steel, and similar machinable metals where a consistent 60-degree UN profile is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiCrAlN\/TiN PVD coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003e10 TPI cutting edge for standard UN external thread profiles\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle matches UN thread form geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand orientation for conventional external threading passes\u003c\/li\u003e\n  \u003cli\u003eA-style chipbreaker for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCoroThread 266 series insert style 16 seating geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroThread 266 series toolholders that accept size code 16 laydown threading inserts with a 3\/8-inch inscribed circle.
