Manufactured to a 60-degree included angle and finished with a TiN (titanium nitride) coating applied via PVD process, this insert delivers consistent thread geometry and wear resistance across a broad range of workpiece materials. The 3ER insert style features a 9.53 mm (3\/8 inch) inscribed circle and a thickness of 3.60 mm. It is intended for right-hand external threading operations on CNC lathes and turning centers. The VKX grade designation identifies the carbide substrate and coating combination optimized for universal material compatibility.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external UNJ thread production in both production machining and maintenance-repair-overhaul (MRO) environments. UNJ thread forms are specified under MIL-S-8879C for aerospace and defense fastener applications, making this insert a common choice for shops producing aerospace-grade threaded components. Compatible workpiece materials span a wide range, including carbon steels, stainless steels, cast irons, non-ferrous alloys, high-temperature alloys, and titanium, as indicated by universal workpiece 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 construction with TiN coating via PVD process for extended tool life\u003c\/li\u003e\n  \u003cli\u003e32 TPI right-hand external UNJ thread profile at 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e3ER insert style with 9.53 mm inscribed circle for standard toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eVKX grade rated for universal workpiece material compatibility across H, K, M, N, P, and S material codes\u003c\/li\u003e\n  \u003cli\u003eMeets MIL-S-8879C and ISO 9001:2008 standards for aerospace-grade threading applications\u003c\/li\u003e\n  \u003cli\u003eSingle-tooth profile per side ensures precise thread form control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3ER-series laydown threading toolholders.
