Part of the CoroThread 266 series, it carries a PVD-applied dual-layer TiCrAlN\/TiAlN coating that supports wear resistance at elevated cutting speeds. The insert is sized at a 3\/8-inch inscribed circle and 5\/32-inch thickness, with a 60-degree included angle and 14 threads per inch. It is intended for use by machinists and toolroom professionals working on precision pipe-thread applications where leak-free NPTF fit is required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading operations on NPTF pipe fittings and components across production machining and maintenance environments. The 266RL-16NF01A140E 1125 geometry designation indicates a right-hand orientation with a single tooth per side and chipbreaker style A, making it appropriate for controlled-chip threading passes in CNC turning centers and manual lathes equipped with CoroThread 266 toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiCrAlN\/TiAlN dual-layer coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e14 TPI right-hand internal NPTF thread profile with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch (9.53 mm) inscribed circle; 5\/32-inch (3.97 mm) thickness\u003c\/li\u003e\n  \u003cli\u003eChipbreaker style A for consistent chip control on internal threading passes\u003c\/li\u003e\n  \u003cli\u003eCoroThread 266 series insert style 266, size code 16\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 1125 for balanced hardness and toughness in threading applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CoroThread 266 series toolholders accepting size-16 laydown threading inserts.
