Built from solid carbide and finished with a PVD-applied TiCrAlN\/TiAlN dual-layer coating, this insert delivers wear resistance and thermal stability during threading operations. It features a 60-degree included angle, 18 threads per inch, a 3\/8 inch inscribed circle, and measures 5\/32 inch thick. Belonging to the CoroThread 266 series, it is intended for right-hand external threading and is well suited for machinists and tooling professionals working on pipe fitting and fluid system components requiring NPT thread profiles.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in CNC lathe and turning center applications where NPT-standard external threads must be cut with precision and repeatability. The single-tooth-per-side geometry and chipbreaker style A support controlled chip formation during threading passes. Typical applications include producing tapered pipe threads on fittings, valve bodies, and connectors in production and job shop environments. It is sold individually and is subject to a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiCrAlN\/TiAlN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e18 TPI for NPT external tapered pipe thread standard\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle with chipbreaker style A for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation for standard lathe threading operations\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle and 0.1563 inch thickness for consistent insert seating\u003c\/li\u003e\n  \u003cli\u003eCoroThread 266 series insert style 266, size code 16\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement threading insert for CoroThread 266 series toolholders accepting size 16 laydown inserts.
