With 4 flutes and a TiAlN coating, this tool handles threading operations on a variety of workpiece materials while maintaining cutting edge durability at elevated temperatures. The cutting diameter is 0.305 inches with a 0.312-inch shank diameter, and threads are cut at 18 teeth per inch. Licensed machinists and CNC operators working in precision manufacturing, pipe fitting production, or maintenance shops will find this tool suited for tight-tolerance NPT thread work.\u003c\/p\u003e\u003cp\u003eThis thread mill is applied in machining centers where NPT tapered threads in the 1\/4-inch and 3\/8-inch nominal sizes are required. It covers both internal threads in fittings, manifolds, and housings and external threads on pipe ends or turned components. With a 0.625-inch length of cut and 3-inch overall length, it fits standard toolholders on vertical and horizontal machining centers. The TiAlN coating supports dry or semi-dry cutting and extends tool life in ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts NPT tapered threads in 1\/4-inch and 3\/8-inch sizes with a single tool\u003c\/li\u003e\n\u003cli\u003eInternal and external thread capability eliminates the need for separate tools\u003c\/li\u003e\n\u003cli\u003e4-flute helical geometry provides balanced cutting forces and smooth thread form\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and extends tool life in production environments\u003c\/li\u003e\n\u003cli\u003e0.312-inch shank diameter fits standard CNC toolholders and shrink-fit chucks\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup on standard machining centers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit thread mill for CNC machining centers accepting a 0.312-inch shank diameter and programmed for NPT tapered pipe thread cycles.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by a qualified CNC machinist or toolroom professional. Secure the shank in a properly sized collet or toolholder and verify runout before cutting to protect thread accuracy. Program the machine for helical interpolation as required by NPT thread geometry. Follow all machine guarding and lockout-tagout procedures before tool changes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Sizes\u003c\/strong\u003e: 1\/4 inch and 3\/8 inch\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: 18 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.305 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.375 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: 0.12 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: TM18NPT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51752925724978,"sku":"TM18NPT","price":259.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/afdff0020b2a0ccb781c7c63caf75c3a.jpg?v=1788931179","url":"https:\/\/voomisupply.com\/products\/allied-machine-tm18npt-thread-mill-1-4-3-8-npt-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
