Part of the Top Notch series, it carries the NWC3L11I designation and is manufactured to the KC5025 grade with a TiAlN finish applied via PVD coating process. This insert is configured for left-hand internal threading at 11 TPI with a 55-degree included angle, making it a precise, application-specific tool for machinists and CNC lathe operators working on Whitworth-standard threaded bores. The insert measures 0.1949 inches in thickness with a corner radius of 0.0118 inches.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading applications on Whitworth-standard workpieces in production and job-shop machining environments. The KC5025 carbide grade with PVD TiAlN coating is typically selected for threading ferrous and alloy materials where wear resistance and edge retention are required. It fits Top Notch series toolholders designed for size 3 inserts. This is a left-hand configuration and should be selected accordingly when threading left-hand internal Whitworth features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 carbide grade with TiAlN finish for wear resistance in ferrous threading\u003c\/li\u003e\n\u003cli\u003ePVD coating process for tight dimensional control and sharp edge retention\u003c\/li\u003e\n\u003cli\u003eLeft-hand internal threading configuration at 11 TPI\u003c\/li\u003e\n\u003cli\u003e55-degree included angle for Whitworth thread standard compliance\u003c\/li\u003e\n\u003cli\u003eTop Notch series size 3 insert geometry\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0118 inches for precise thread form\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders that accept size 3 threading inserts.
