It runs at 12 threads per inch with a 3\/8-inch inscribed circle and a 0.146-inch thickness, following the 16IR insert style standard. The insert is manufactured from micrograin solid carbide and finished with a PVD-applied TiN coating for extended tool life across a wide range of workpiece materials. The included angle is 45 degrees, consistent with standard Acme thread geometry. This is a right-hand insert intended for internal threading operations. Machinists and toolroom technicians working in general manufacturing, maintenance, and production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal Acme thread cutting in both prototype and production runs across universal workpiece material categories, including ferrous metals, stainless steels, cast materials, non-ferrous alloys, plastics, and heat-resistant alloys. The Acme thread form is common in lead screws, power transmission components, vises, and linear actuators. The MXC grade and micrograin carbide substrate make the 16IR12ACMEMXC a general-purpose threading solution capable of handling varied materials without requiring frequent grade changes between jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate in the MXC grade for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiN coating extends cutting edge life across universal material groups\u003c\/li\u003e\n  \u003cli\u003e12 TPI Acme thread form with a 45-degree included angle for accurate internal thread geometry\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle (0.3750 inches) and 0.146-inch thickness conform to 16IR insert style dimensions\u003c\/li\u003e\n  \u003cli\u003eRight-hand orientation for standard internal threading pass direction\u003c\/li\u003e\n  \u003cli\u003eCompatible material codes H, K, M, N, P, and S cover the broadest range of common workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders accepting the 16IR insert style.
