It carries a TiAlN finish applied via PVD coating process, which provides thermal resistance and edge wear protection during threading operations. The insert uses a 60-degree included angle standard for UN thread form and is configured for right-hand cutting. With a tip-to-top height of 0.1480 inches and a thickness of 0.1949 inches, this insert fits within the Top Notch series tooling system. It is installed and indexed by machinists and CNC operators working with precision threaded components.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external threading applications on lathes and turning centers where UN-standard threads at 32 TPI are required. The KC5025 grade carbide with TiAlN coating makes it appropriate for a range of metalcutting conditions, including interrupted cuts and production threading on steel and similar materials. The Top Notch series designation indicates compatibility with Kennametal Top Notch-style threading toolholders designed for this insert geometry and size class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e32 TPI external UN thread form with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD finish coating for extended tool life and heat resistance\u003c\/li\u003e\n  \u003cli\u003eKC5025 carbide grade rated for C2 and C6 material classifications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting configuration\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0039 inches for controlled thread root geometry\u003c\/li\u003e\n  \u003cli\u003eTop Notch series insert style for use with compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Kennametal Top Notch series threading toolholders accepting NTC3-style inserts.
