Designed for use on CNC lathes and threading machines, this insert features a 60-degree included angle standard to Unified National thread profiles. The PVD-applied TiN (titanium nitride) gold coating improves surface hardness and extends cutting edge life across a wide range of workpiece materials. At 0.375 inches inscribed circle and 0.146 inches thick, this is a 16ER-style insert suitable for high-precision threading operations performed by machinists and toolroom professionals.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for universal workpiece material compatibility, covering material grade codes H, K, M, N, P, and S. That makes it suitable for threading carbon steels, stainless steels, cast iron, non-ferrous metals, and high-temperature alloys in both production and job-shop environments. Typical applications include external thread turning on shafts, fasteners, and hydraulic fittings where UN thread form accuracy is required. The P25C manufacturer grade places it in the mid-range carbide spectrum, balancing toughness and wear resistance for general-purpose threading passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiN coating for extended edge life\u003c\/li\u003e\n  \u003cli\u003e32 TPI Unified National (UN) external thread profile, 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e16ER insert style, 3\/8 inch (0.375 inches) inscribed circle\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for standard lathe threading setups\u003c\/li\u003e\n  \u003cli\u003eUniversal material grade compatibility: H, K, M, N, P, and S workpiece codes\u003c\/li\u003e\n  \u003cli\u003eManufactured to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement threading insert for 16ER-style toolholders accepting a 3\/8 inch inscribed circle laydown insert for external UN thread applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians on CNC or manual lathes. Power down and lock out the machine before seating or replacing inserts. Use the correct torque wrench and insert screw for the toolholder to avoid micro-fracturing the carbide substrate.
