Built from micrograin solid carbide and coated with a PVD-applied TiAlN\/TiN finish under the CP500 grade designation, this insert delivers the wear resistance and edge stability required when threading stainless steel and similarly demanding materials. The 16ER insert style seats in compatible laydown toolholders and produces 60-degree thread forms to UN standards. With a 3\/8-inch inscribed circle and a thickness of 0.1366 inches, it fits a common range of indexable threading systems used in production and job-shop turning operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading applications on CNC lathes and manual turning centers. Its right-hand cutting orientation and A2 chipbreaker geometry make it a practical choice for threading operations on stainless steel workpieces where chip control and surface finish consistency are priorities. The Snap Tap series design supports repeatable indexing and consistent thread quality across production runs. Machinists and tooling specialists working in precision machining, aerospace component work, or general metalworking will find this insert appropriate for high-demand threading cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for improved edge retention on tough materials\u003c\/li\u003e\n\u003cli\u003ePVD-applied TiAlN\/TiN coating under CP500 grade for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e16 TPI UN external thread form with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation with A2 chipbreaker geometry for stainless steel chip control\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle fits standard laydown threading toolholders\u003c\/li\u003e\n\u003cli\u003eISO-standard insert geometry for predictable fitment and indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for laydown threading toolholders accepting the 16ER insert style with a 3\/8-inch inscribed circle, suitable for external UN thread turning operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Power down and de-energize the machine spindle before seating or indexing the insert.
