Built from solid carbide with a TiN coating applied via PVD process, this insert delivers consistent thread form geometry on a wide range of workpiece materials. It cuts Unified National (UN) thread forms at 12 threads per inch with a 60-degree included angle. The right-hand configuration and 16IR insert style make it a direct fit for standard 16-series laydown threading toolholders. Machinists and CNC operators in production and job-shop environments install this insert for reliable, repeatable internal threading performance.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading operations on both ferrous and non-ferrous materials. The MXC grade designation indicates a universal carbide substrate with PVD TiN coating, making it appropriate for steel, stainless steel, cast iron, aluminum, non-ferrous alloys, and high-temperature alloys. It is commonly used in residential, commercial, and industrial machining applications wherever 12 TPI UN internal threads are required. The 3\/8-inch inscribed circle dimension corresponds to the 16-series insert size standard.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal UN thread form at 12 threads per inch with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction with TiN coating via PVD process for extended edge life\u003c\/li\u003e\n\u003cli\u003eMXC universal grade compatible with steel, stainless, cast iron, aluminum, non-ferrous, and high-temperature alloys\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard internal threading setups\u003c\/li\u003e\n\u003cli\u003e16IR insert style with 3\/8-inch inscribed circle for use in 16-series laydown toolholders\u003c\/li\u003e\n\u003cli\u003eCertified to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for 16-series laydown internal threading toolholders accepting 16IR-style inserts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and replaced by CNC machinists and tool-crib technicians using standard insert-locking screws and torx or hex keys specified by the toolholder manufacturer. Power down and de-energize the machine spindle before changing inserts. Inspect the toolholder pocket and clamping screw for wear or damage before seating a new insert.
