The insert features a micrograin carbide substrate in the MXC manufacturer grade, finished with a PVD-applied TiN coating for extended tool life across a broad range of workpiece materials. The 45-degree included angle and 1-degree relief angle are ground to suit right-hand external Buttress thread geometry. With an inscribed circle of 0.5 inches and a thickness of 0.187 inches, this insert fits standard 22 ER-style toolholders. Machinists and toolroom operators install this insert on CNC lathes and manual turning centers for single-pass or multi-pass threading operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external Buttress thread applications across universal workpiece materials, including steel, stainless steel, cast iron, non-ferrous alloys, high-temperature alloys, and titanium, corresponding to material codes H, K, M, N, P, and S. It is appropriate for both production and job-shop environments where American Buttress thread forms are specified. The MXC grade with TiN PVD coating provides wear resistance that supports consistent thread quality across mixed-material work orders without requiring a grade change between setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate in MXC grade for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003ePVD TiN coating applied for reduced friction and extended insert life\u003c\/li\u003e\n\u003cli\u003e8 TPI American Buttress external thread profile with 45-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard external threading operations\u003c\/li\u003e\n\u003cli\u003e0.5-inch inscribed circle fits 22 ER-style insert pockets\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across H, K, M, N, P, and S workpiece codes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 22 ER-style laydown threading toolholders.
