It carries a TiAlN coating applied via a PVD process, which provides wear resistance and thermal stability during interrupted cutting. The insert uses the STN style geometry and is rated at 10 teeth per inch (TPI) with an inscribed circle of 0.625 inches (15.88 mm). This insert is intended for use by machinists and tooling technicians working in precision thread milling applications where consistent thread form and tool life are required.\u003c\/p\u003e\n\u003cp\u003eThe 2393680 is suited for external UN thread milling on ferrous and hard materials in CNC machining environments. The STN insert style and KC635M grade make it applicable in production and job-shop settings where thread form accuracy and surface finish are priorities. It is sold individually but requires a minimum order quantity of 5 units per order. Installation into a compatible thread mill toolholder is required before use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide substrate in KC635M grade for wear resistance in thread milling\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating via PVD process for thermal and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eSTN insert style for external UN thread applications\u003c\/li\u003e\n  \u003cli\u003e10 teeth per inch for standard UN thread form production\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 0.625 inches (15.88 mm)\u003c\/li\u003e\n  \u003cli\u003eNon-conical geometry for consistent thread profile\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use insert for thread mill toolholders accepting STN-style carbide inserts in external UN thread milling configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine before seating or replacing inserts. Ensure the toolholder is clean and free of debris before installing the insert. Verify that the toolholder is rated for the STN insert style and that all clamping hardware is properly torqued per the toolholder manufacturer specifications before resuming operation.\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\u003eThread Type\u003c\/strong\u003e: External\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: 10 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.625 inches (15.88 mm)\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\u003eConical\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 2393680\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733931098418,"sku":"2393680","price":828.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/98d0b27a7f4b8612247bd30b8c73e039.jpg?v=1788760026","url":"https:\/\/voomisupply.com\/products\/kennametal-2393680-carbide-thread-mill-insert-un-10-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
