Using manufacturer grade KC635M carbide with a PVD-applied TiAlN coating, this insert delivers hard, wear-resistant cutting edges suited for demanding thread milling operations. The STN insert style features an inscribed circle of 0.25 inches (6.35 mm) and is designed for use in thread milling toolholders that accept this geometry. Licensed machinists and CNC operators working in job shop and production environments rely on this insert for consistent thread form and extended tool life in steel, stainless, and other hard materials.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal thread milling of UN-standard threads at 24 teeth per inch. It fits thread mill bodies that accept the STN insert style and is suited for CNC machining centers performing internal threading operations in ferrous and non-ferrous materials. The TiAlN coating enhances heat resistance at the cutting zone, making it appropriate for dry or minimal-lubrication machining strategies. Typical applications include producing tapped holes in production parts where rigid tapping is not practical or where thread quality requirements are high.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\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 use in compatible thread mill toolholders\u003c\/li\u003e\n\u003cli\u003eInternal UN thread standard at 24 TPI\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003eNon-conical geometry for standard thread form\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in thread milling toolholders that accept the STN insert style for internal UN thread milling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and replacement of thread milling inserts should be performed by qualified machinists or CNC tooling technicians. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing inserts. Use the correct torque driver for the insert clamping screw to avoid seat damage or insert movement during cutting. Verify thread form and pitch against the required UN specification using a calibrated thread gauge after setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\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: 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 2384513\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731830276402,"sku":"2384513","price":899.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a568c317df27bfba8b732fa4a182ac6.jpg?v=1788735406","url":"https:\/\/voomisupply.com\/products\/kennametal-2384513-carbide-thread-mill-insert-un-24-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
