Built to the 3ER insert style with a 3\/8-inch (9.53 mm) inscribed circle and a thickness of 3.6 mm, this insert delivers precise, repeatable thread geometry on a wide range of workpiece materials. The TiAlN coating is applied via PVD process, providing thermal resistance and extended tool life under demanding cutting conditions. It carries a 60-degree included angle and a single tooth per side configuration. Machinists and CNC turning specialists working in aerospace, defense, and precision machining environments will find this insert meets both ISO 9001:2008 and MIL-S-8879C standards.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for right-hand external threading operations on lathes and turning centers where UNJ thread profiles are required. The UNJ standard specifies a controlled root radius, making it a common specification in aerospace fastener and structural applications governed by MIL-S-8879C. The universal primary workpiece material classification covers a broad material range including carbon steels, stainless steels, cast irons, non-ferrous alloys, high-temp alloys, and titanium alloys, indicated by material codes H, K, M, N, P, and S.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiAlN coating for high-temperature wear resistance\u003c\/li\u003e\n  \u003cli\u003e3ER insert style, 24 TPI, 60-degree included angle for UNJ external thread profile\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle (9.53 mm) and 3.6 mm thickness for standard laydown toolholders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting configuration\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 9001:2008 and MIL-S-8879C standards\u003c\/li\u003e\n  \u003cli\u003eCompatible with universal workpiece materials: H, K, M, N, P, and S material groups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in laydown threading toolholders accepting 3ER-style inserts with a 3\/8-inch inscribed circle.
