It operates at 4 threads per inch (TPI) with a right-hand cutting orientation and features a 1\/2 inch inscribed circle (IC) and a thickness of 0.187 inches. The P25C manufacturer grade with PVD-applied TiN coating provides wear resistance across a wide range of workpiece materials. Machinists and CNC operators use this insert for producing precision internal Acme thread forms in production and maintenance machining environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal Acme thread applications in both light production and job-shop settings. The 29-degree included angle matches the Acme thread standard profile. Its universal primary workpiece material rating covers a broad spectrum of materials, making it adaptable across ferrous and non-ferrous applications. Typical installations involve threading bores in mechanical components such as lead screws, jacks, and linear actuators where Acme thread forms are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD TiN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e4 TPI Acme thread profile with 29-degree included angle\u003c\/li\u003e\n  \u003cli\u003eRight-hand, internal thread cutting orientation\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch inscribed circle (IC), 0.187 inches thick\u003c\/li\u003e\n  \u003cli\u003eP25C grade (material grade C5) rated for universal workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMeets 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 22IR-series toolholders accepting laydown threading inserts with a 1\/2 inch inscribed circle.
