Built from solid carbide with a TiC\/TiN coating, it delivers consistent thread form and wear resistance in demanding machining environments. The insert carries a 16IR style designation, a 3\/8 inch inscribed circle, and cuts at 24 threads per inch. A 0.146 inch thickness and zero-degree relief angle define its seating geometry. This insert is installed and indexed by machinists and CNC operators performing internal threading passes on lathes and turning centers in production or job-shop settings.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading of UN-standard fastener and component threads in ferrous and non-ferrous materials. The 24 TPI specification targets fine-thread applications common in hydraulic fittings, instrumentation hardware, and precision mechanical assemblies. The TiC\/TiN finish extends tool life on abrasive workpiece materials. This insert is sold individually, with a minimum order quantity of 10 units, making it appropriate for shop stock replenishment or toolroom inventory.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate for rigidity and edge retention in interrupted and continuous threading cuts\u003c\/li\u003e\n\u003cli\u003eTiC\/TiN multilayer coating reduces friction and extends wear life\u003c\/li\u003e\n\u003cli\u003e24 TPI cutting edge conforms to UN thread standard for internal thread profiles\u003c\/li\u003e\n\u003cli\u003e16IR insert style with 3\/8 inch inscribed circle fits standard laydown threading toolholders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting geometry for conventional internal threading direction\u003c\/li\u003e\n\u003cli\u003eZero-degree relief angle provides stable seating in laydown-style pockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in laydown threading toolholders accepting 16IR-style inserts with a 3\/8 inch inscribed circle.
