Manufactured in the KC635M grade and finished with a PVD-applied TiAlN coating, this insert delivers wear resistance and thermal stability during aggressive thread milling operations. It is configured for NPT (National Pipe Taper) threading at 11.5 TPI and features a 5\/8-inch (0.6250 inch) inscribed circle diameter. Licensed machinists and toolroom professionals use this insert in CNC machining centers where helical interpolation replaces traditional tapping for greater process control and tool life.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for shops producing NPT-threaded features in production or job-shop environments. Its STN insert style accommodates standard thread mill toolholders configured for that geometry. The TiAlN coating makes it appropriate for dry or near-dry cutting conditions as well as operations involving harder workpiece materials where heat generation is a concern. Both pipe fitting component manufacturers and maintenance machining operations will find this insert applicable for producing leak-free NPT-standard threads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC635M carbide grade with PVD TiAlN coating for extended tool life in demanding thread milling\u003c\/li\u003e\n  \u003cli\u003eNPT thread standard at 11.5 TPI for pipe thread applications requiring taper conformance\u003c\/li\u003e\n  \u003cli\u003eCompatible with both internal and external thread milling operations\u003c\/li\u003e\n  \u003cli\u003eSTN insert style geometry for use in matching thread mill bodies\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch (0.6250 inch) inscribed circle diameter for consistent seating and repeatability\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.0269 pounds, suitable for high-speed rotating tooling assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for thread mill bodies accepting the STN insert style.

Use the correct torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten, as carbide inserts are brittle and can fracture under excessive clamping force. Verify insert seating and runout before initiating a thread milling cycle. Program helical interpolation parameters according to the thread mill body manufacturer specifications and the NPT taper requirements of the application.\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 Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 11.5 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inch \/ 15.88 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: 0.0269 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 2429566\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734486057266,"sku":"2429566","price":1085.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d6154c6da835bb6f57a3f5a248cf987.jpg?v=1788763199","url":"https:\/\/voomisupply.com\/products\/kennametal-2429566-carbide-thread-mill-insert-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
