It features a 3\/8-inch inscribed circle (IC), a 60-degree included angle, and a TiN coating applied via PVD process. This insert is engineered for right-hand external threading operations on CNC lathes and turning centers. The VKX grade designation indicates a universal cutting grade suited for a wide range of workpiece materials. Licensed machinists and CNC operators use this insert for precision thread cutting in demanding production environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading applications across a broad spectrum of workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys, as reflected in the multi-code material classification. The UNJ thread standard specifies a controlled root radius, making this insert appropriate for aerospace and military-grade fastener threads where MIL-S-8879C compliance is required. It is used in both production shops and job shops running tight-tolerance threaded components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD-applied TiN coating for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eUNJ thread form with 60-degree included angle and controlled root radius per MIL-S-8879C\u003c\/li\u003e\n\u003cli\u003e16 TPI right-hand external thread geometry in standard 3ER insert style\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle for use in compatible laydown insert toolholders\u003c\/li\u003e\n\u003cli\u003eUniversal grade VKX suitable for steel, stainless, cast iron, non-ferrous, and superalloy materials\u003c\/li\u003e\n\u003cli\u003eISO 9001:2008 certified manufacturing process\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in laydown-style external threading toolholders accepting the 3ER insert style with a 3\/8-inch inscribed circle.
