Built from solid carbide with a PVD-applied TiCrAlN\/TiN coating, this insert delivers wear resistance and thermal stability during threading operations. It is configured for right-hand internal threading at 10 threads per inch (TPI) with a 60-degree included angle. The 3\/8-inch inscribed circle and 5\/32-inch thickness place it in the CoroThread 266 series, making it a purpose-built insert for precision thread forms on CNC lathes and turning centers operated by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal UN thread applications in production and job-shop environments. It is used on CNC turning centers and lathes where consistent thread form and dimensional accuracy are required. The single-tooth-per-side geometry and chipbreaker style A are optimized for controlled chip evacuation during internal threading passes. Typical applications include threading bores in ferrous and non-ferrous workpieces where UN thread standards apply.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiCrAlN\/TiN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal UN thread configuration at 10 TPI\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle for standard UN thread form\u003c\/li\u003e\n  \u003cli\u003eChipbreaker style A for controlled chip flow in internal threading\u003c\/li\u003e\n  \u003cli\u003eCoroThread 266 series insert with style code 266RL-16UN01A100M\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch (9.53 mm) inscribed circle with 4.40 mm mounting hole diameter\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 laydown threading inserts with a 16-size insert code and 3\/8-inch inscribed circle, as specified by the manufacturer for internal UN threading applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis insert is installed by a qualified machinist or toolroom technician following the toolholder manufacturer's torque and clamping specifications.
