Built from solid carbide and coated with TiAlN for heat and wear resistance, this tool handles 1\/4-18 and 3\/8-18 NPTF thread sizes in a single tool. It runs 3 right-hand flutes with an 18 TPI cutting profile, a 0.3120-inch cutting diameter, and a 0.5800-inch length of cut. Overall length is 2.5000 inches, with a 0.3120-inch shank diameter. Licensed machinists and CNC operators use this tool in precision threading operations where tapered pipe thread forms are required.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for shops producing or servicing components that require NPTF tapered pipe thread connections, including fittings, manifolds, hydraulic blocks, and fluid system housings. It handles both internal and external thread forms, reducing the need for separate tools per application. The helical flute geometry supports smooth chip evacuation during the milling cycle. Typical installations occur in CNC machining centers using helical interpolation routines specific to thread milling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts both internal and external NPTF threads  -  1\/4-18 and 3\/8-18 sizes\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves heat resistance and reduces tool wear at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e3 right-hand helical flutes promote efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e18 TPI, 0.3120-inch cutting diameter, 0.5800-inch length of cut\u003c\/li\u003e\n  \u003cli\u003e2.5000-inch overall length with 0.3120-inch shank diameter for standard collet or end mill holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation; fits standard tool holders accepting a 0.3120-inch shank diameter and is sized to cut 1\/4-18 and 3\/8-18 NPTF thread forms.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread milling with this tool requires a CNC control that supports helical interpolation  -  confirm the program is written for thread milling, not tapping. Secure the shank firmly in a collet chuck or end mill holder with minimal runout to protect the carbide cutting edges. Inspect the tool for edge damage before each use; carbide is brittle and sensitive to impact. Coolant-through is not supported on this tool, so ensure adequate external coolant or air blast is directed at the cut zone to manage chip clearing and heat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Sizes\u003c\/strong\u003e: 1\/4-18 and 3\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.3120 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3120 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.2500 inches\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: 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: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5604066\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51741547364658,"sku":"5604066","price":353.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3b43e56a42e89fefd4b376af61e8e98_0d0be5c2-f716-4805-8430-74dba7a7ec31.jpg?v=1788832105","url":"https:\/\/voomisupply.com\/products\/iscar-5604066-thread-mill-1-4-18-3-8-18-nptf-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
