It features five right-hand flutes and an EgiAs coating for extended tool life in demanding materials. The cutting diameter measures 0.6170 inches with a length of cut of 0.7860 inches, and the shank diameter is 0.6250 inches. At 14 teeth per inch, this tool produces accurate NPT taper thread forms in a single helical interpolation pass. Solid carbide construction provides rigidity and edge retention suited to production threading applications. Licensed machinists and CNC programmers working in metalworking, pipe fitting fabrication, or industrial maintenance are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for generating 1\/2-14 NPT threaded features in machining centers equipped with helical interpolation capability. NPT threads are used throughout fluid and gas piping systems in plumbing, HVAC, and industrial process piping where tapered thread sealing is required. The tool is appropriate for through and blind hole applications where tap breakage is a concern or where a single tool must cover multiple thread diameters through programmatic offset adjustment. No coolant-through capability is present, so external coolant or air blast is recommended during operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-14 NPT thread form with 14 TPI taper pipe thread standard\u003c\/li\u003e\n\u003cli\u003eFive right-hand helical flutes for smooth chip evacuation\u003c\/li\u003e\n\u003cli\u003eEgiAs coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate provides stiffness and dimensional stability\u003c\/li\u003e\n\u003cli\u003e0.6170 inch cutting diameter with 0.7860 inch length of cut\u003c\/li\u003e\n\u003cli\u003eSingle tool capable of threading multiple hole diameters via CNC offset\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation; produces 1\/2-14 NPT tapered pipe thread forms per the NPT thread standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread mills are installed and operated by machinists or CNC programmers on 3-axis or higher machining centers. Confirm the machine control supports helical interpolation before programming this tool. Secure the shank in a collet or end mill holder rated for the 0.6250 inch shank diameter and verify runout before cutting. Use appropriate feeds, speeds, and external coolant or air blast, as this tool does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.6170 inches (0.62 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7860 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Package Length\u003c\/strong\u003e: 4.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.85 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: EgiAs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16630\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1663000417\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731736166706,"sku":"1663000417","price":757.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9b17beafb22a147a80f0ff47baff9f9_9eb2ff99-928c-45a4-8f17-372bf3f068ff.jpg?v=1788734366","url":"https:\/\/voomisupply.com\/products\/osg-1663000417-thread-mill-1-2-14-npt-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
