Manufactured from submicron-grade solid carbide and coated with TiAlN via a PVD process, this insert delivers wear resistance and thermal stability across a wide range of workpiece materials. With a 3\/8-inch inscribed circle and 0.146-inch thickness, it fits standard laydown insert toolholders used in CNC and manual lathe threading operations. Machinists and toolroom technicians install this insert for right-hand internal threading applications where consistent thread form and tool life are priorities.\u003c\/p\u003e\u003cp\u003eThis insert is suited for threading operations on a broad range of materials, including ferrous, non-ferrous, stainless, high-temp alloys, and cast materials, as indicated by its universal primary workpiece material rating. The 16 TPI UN thread form and 29-degree included angle make it appropriate for producing standard Unified National thread profiles in internal bores on production runs or maintenance work in job shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with submicron-grade material for extended edge life\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating for heat resistance and reduced wear at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e16 TPI UN internal thread form with a 29-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard internal threading setups\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle fits common laydown-style threading toolholders\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across ferrous, non-ferrous, stainless, and high-temp alloy workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in laydown-style internal threading toolholders accepting a 16IR insert style with a 3\/8-inch inscribed circle.
