With 4 right-hand flutes, a 0.495-inch cutting diameter, and a TiAlN coating, this tool delivers wear resistance and thermal stability in demanding CNC machining environments. It cuts 14 teeth per inch (TPI) and offers a 0.875-inch length of cut, making it suited for productive single-pass or multi-pass thread milling cycles in ferrous and non-ferrous materials. The 0.5-inch shank diameter and 3.5-inch overall length are compatible with standard ER and end mill toolholders.\u003c\/p\u003e\u003cp\u003eThis thread mill is used in CNC machining centers for producing 1\/2 and 3\/4 NPT pipe threads. NPT threads are standard in plumbing, hydraulic, and pneumatic fittings, making this tool common in job shops, production machining, and maintenance machining operations. Both internal threads in pipe ports and external threads on pipe nipples are within its designed application range. It is typically installed and run by CNC machinists working to pipe thread tolerances on parts requiring fluid or gas sealing connections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts 1\/2 and 3\/4 NPT threads in a single tool — internal and external capable\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and long tool life in production environments\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and extends tool life in dry or semi-dry cutting conditions\u003c\/li\u003e\n\u003cli\u003e4 right-hand helical flutes for smooth chip evacuation and consistent thread form\u003c\/li\u003e\n\u003cli\u003e14 TPI thread pitch with 0.495-inch cutting diameter and 0.875-inch length of cut\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design — suitable for external coolant application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC machining centers producing 1\/2 and 3\/4 NPT pipe threads in internal and external configurations.

Secure the shank in a properly sized collet or end mill holder with adequate tool stick-out for the required depth of cut. Thread milling requires correct helical interpolation programming — verify the toolpath direction matches the right-hand flute geometry before running. Inspect the cutting edges before each run; carbide tools are brittle and can fracture if impacted against hardened surfaces or run in worn toolholders.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2, 3\/4\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 (TPI)\u003c\/strong\u003e: 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: 0.495 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ALLIED MACHINE AND ENGINEERING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM14NPT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51730623299890,"sku":"TM14NPT","price":404.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6e14f77a9b54ddf98d472af5701fc48.jpg?v=1788720432","url":"https:\/\/voomisupply.com\/products\/allied-machine-tm14npt-npt-thread-mill-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
