Manufactured in insert style STN with a KC635M grade carbide substrate, this insert features a TiAlN (titanium aluminum nitride) PVD coating for extended tool life and heat resistance at elevated cutting speeds. It is configured for UN (Unified National) thread standards at 14 teeth per inch (TPI). The inscribed circle measures 3\/8 inch (9.53 mm). Machinists and CNC operators use this insert in thread milling toolholders to produce precise internal threads in ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal thread milling in CNC machining center environments where UN-standard threads are required. At 14 TPI, it covers common fractional thread sizes encountered in general machining, tooling, and industrial fastener applications. The PVD-applied TiAlN coating supports dry or minimal-lubrication cutting strategies, making it appropriate for production environments focused on reducing coolant consumption without sacrificing tool life or thread quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC635M carbide grade with PVD-applied TiAlN coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSTN insert style for compatibility with designated thread milling toolholders\u003c\/li\u003e\n  \u003cli\u003eInternal thread configuration for IN-bore thread milling operations\u003c\/li\u003e\n  \u003cli\u003eUN thread standard at 14 TPI for common fractional unified thread sizes\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 3\/8 inch (9.53 mm) for precise insert seating\u003c\/li\u003e\n  \u003cli\u003eNon-conical geometry for standard thread form applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement carbide thread mill insert for use in STN-style thread milling toolholders configured for UN internal threading applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or replacing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified clamping procedure  -  do not overtighten the clamping screw. Verify insert seating and runout before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: STN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC635M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConical\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2384517\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743824675122,"sku":"2384517","price":942.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d65bee4045d8bcbafcedfe0d5bd5edce.jpg?v=1788850069","url":"https:\/\/voomisupply.com\/products\/kennametal-2384517-carbide-thread-mill-insert-un-14-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
