It features a 29-degree included angle and a TiN coating applied via PVD process, which improves surface hardness and wear resistance during threading operations. The insert measures 0.375 inches inscribed circle and 0.146 inches thick. Right-hand geometry makes it suitable for standard external threading passes. Machinists and CNC operators install this insert into compatible toolholders for single-point threading on lathes and turning centers handling Acme-profile threads.\u003c\/p\u003e\u003cp\u003eThis insert is suited for a wide range of workpiece materials, including ferrous metals, stainless and heat-resistant alloys, cast iron, non-ferrous metals, and high-temperature materials, consistent with material codes H, K, M, N, P, and S. Typical applications include lead screws, power screws, and jack screws where the Acme thread form is required. It is appropriate for both production and repair threading in job shop and manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiN coating via PVD process for improved wear resistance\u003c\/li\u003e\n\u003cli\u003e12 TPI external Acme thread profile with 29-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting geometry for standard threading direction\u003c\/li\u003e\n\u003cli\u003e3\/8-inch (0.375 inches) inscribed circle, 0.146 inches thick\u003c\/li\u003e\n\u003cli\u003eUniversal material grade suitability across ferrous and non-ferrous workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with toolholders accepting the 16ER insert style for external Acme threading applications.
