Built from submicron-grade carbide and finished with a TiN coating, it delivers consistent thread geometry and extended tool life in production and job-shop environments. The cutter runs 14 teeth per inch (TPI) with a 0.44-inch cutting diameter and a 0.89-inch length of cut, making it well-suited for threading pipe-thread forms in a single helical pass. Machinists and toolroom technicians operating CNC machining centers are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis thread mill handles both 1\/2-14 NPT and 3\/4-14 NPT thread sizes from a single tool, reducing tool changes and simplifying setup on multi-size pipe-thread jobs. The right-hand flute direction and four-flute geometry support smooth chip evacuation and stable cutting action in a range of ferrous and non-ferrous materials. The 1\/2-inch shank diameter fits standard ER or precision collet holders commonly used on CNC milling machines. It is appropriate for use in both production runs and prototype work where NPT pipe thread accuracy is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts both 1\/2-14 NPT and 3\/4-14 NPT threads with one tool, internal and external\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003e4 helical flutes with right-hand flute direction for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e14 TPI matched to NPT pipe thread standard\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies toolholder selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on CNC machining centers capable of helical interpolation; cuts 1\/2-14 NPT and 3\/4-14 NPT thread forms in internal and external configurations using a 1\/2-inch shank collet or milling chuck.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread milling requires a CNC control capable of helical interpolation  -  confirm control compatibility before programming. Secure the 1\/2-inch shank in a balanced, runout-minimized collet holder and verify tool projection matches the required length of cut. Establish correct climb or conventional milling direction per the CAM program and workpiece material. Do not use this tool in manual milling machines or applications that cannot execute circular interpolation with simultaneous Z-axis movement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Sizes\u003c\/strong\u003e: 1\/2-14 NPT, 3\/4-14 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\u003eThread Standard\u003c\/strong\u003e: NPT\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\u003eCutting Diameter\u003c\/strong\u003e: 0.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.89 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0 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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\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: 0.42 pounds\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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TMX440-14-HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52038609666354,"sku":"TMX440-14-HC","price":264.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7867f507b8682c5853d167154050c8c8.jpg?v=1790025509","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmx440-14-hc-thread-mill-npt-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
