It features a TiN PVD coating applied under the MXC micrograin carbide grade designation, which supports extended tool life across a wide range of workpiece materials. The insert has a 60-degree included angle (30-degree flank) suited to NPT thread form, a 3\/8-inch inscribed circle, and a thickness of 0.146 inches. It is used by machinists and toolroom technicians on CNC lathes and manual threading setups requiring right-hand external NPT thread production.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited to pipe thread applications in both production and job-shop environments where NPT external threads must meet dimensional standards. The universal material grade designation covers a broad spectrum of materials including steel, stainless, cast iron, non-ferrous alloys, high-temp alloys, and hardened materials, corresponding to material codes H, K, M, N, P, and S. It is a single insert sold individually, with a minimum order quantity of 50 units, making it appropriate for tooling stock replenishment or production line setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating extends tool life across universal workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand external NPT thread profile at 11.5 TPI\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle and 0.146-inch thickness for 16ER-style toolholders\u003c\/li\u003e\n  \u003cli\u003eCertified to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards\u003c\/li\u003e\n  \u003cli\u003e16ER insert style for standard laydown threading toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 16ER-style laydown threading toolholders.
