Manufactured from submicron-grade solid carbide with a PVD-applied TiAlN coating, this insert delivers consistent thread quality across a broad range of workpiece materials. The 60-degree included angle matches standard UN thread geometry. With a 3\/8-inch inscribed circle and 0.146-inch thickness, it fits standard 16 ER toolholders. This insert is intended for use by machinists and CNC lathe operators performing external threading operations on production or job-shop turning equipment.\u003c\/p\u003e\n\u003cp\u003eThe 16ER8UNBMA is suited for external threading applications on a wide range of materials, including steels, stainless steels, cast irons, non-ferrous metals, high-temperature alloys, and titanium alloys, as reflected by its universal workpiece material rating. Right-hand cutting orientation makes it appropriate for standard right-hand thread production on CNC lathes and turning centers. It is a single-insert-per-package item commonly sourced in quantities of 10 for production environments where consistent tooling inventory is maintained.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide substrate for improved wear resistance and edge integrity\u003c\/li\u003e\n  \u003cli\u003ePVD TiAlN coating supports high cutting speeds and extended tool life across universal workpiece materials\u003c\/li\u003e\n  \u003cli\u003e8 TPI UN external thread form with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle fits standard 16 ER toolholder seats\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for standard external threading\u003c\/li\u003e\n  \u003cli\u003eMeets 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 for use in standard 16 ER laydown threading toolholders for external UN thread applications on CNC lathes and turning centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine before seating or changing inserts. Use the appropriate torque wrench and insert clamp screw as specified by the toolholder manufacturer  -  do not overtighten.
