Manufactured from solid carbide micrograin material and finished with a PVD-applied TiN coating, this insert delivers consistent thread form and extended tool life in demanding turning applications. The 60-degree included angle conforms to the UN thread standard. With a 3\/8 inch inscribed circle and 0.146 inch thickness, the 16ER12UNMXC seats securely in compatible 16ER toolholders. It is installed by CNC machinists and manual lathe operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for right-hand external threading operations on a broad range of workpiece materials. The universal material grade designation covers steel, stainless steel, cast iron, non-ferrous alloys, and high-temperature alloys, making it a versatile choice for general threading work. Typical applications include producing standard UN fastener threads on turned components in aerospace, automotive, and general manufacturing settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for improved wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating reduces friction and extends cutting life\u003c\/li\u003e\n  \u003cli\u003e12 TPI UN thread profile with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eRight-hand external thread geometry for standard OD threading operations\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle fits standard 16ER toolholder pockets\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility across steel, stainless, cast iron, non-ferrous, and superalloys\u003c\/li\u003e\n  \u003cli\u003eCertified to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 16ER laydown threading toolholders accepting a 3\/8 inch inscribed circle insert.
