It carries four right-hand flutes, a 0.3750-inch cutting diameter, and an 18-tooth-per-inch (TPI) pitch, making it suitable for generating 1\/4-18 and 3\/8-18 NPTF thread forms in a single helical interpolation pass. The tool is coated with TiAlN for heat resistance and extended tool life in ferrous and hard materials. Coolant-through capability supports chip evacuation during deep or interrupted thread cuts. Licensed machinists and CNC operators working in production or maintenance environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used in CNC machining centers capable of helical interpolation. It handles both 1\/4-18 NPTF and 3\/8-18 NPTF thread forms, covering the two most common small-diameter tapered pipe thread sizes found in hydraulic, pneumatic, and fluid-transfer fittings. Its 3\/8-inch shank diameter and 3.0000-inch overall length make it compatible with standard end mill toolholders. The 0.6400-inch length of cut accommodates typical thread engagement depths for NPTF pipe fittings. Applications include thread milling in aluminum, steel, stainless, and cast iron workpieces where tap breakage risk or thread quality requirements favor a milling approach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts both 1\/4-18 and 3\/8-18 NPTF tapered pipe threads with one tool\u003c\/li\u003e\n  \u003cli\u003eInternal and external thread milling capability in a single setup\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand helical design for balanced cutting forces\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves heat resistance and tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eCoolant-through construction supports chip evacuation and tool cooling at depth\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and dimensional accuracy across thread forms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with helical interpolation capability; accepts standard 3\/8-inch end mill toolholders.

Verify toolholder runout before use, as carbide thread mills are sensitive to radial deviation. Confirm workpiece is securely fixtured and spindle speed and feed rate are programmed per the material grade MT7 recommendations from the manufacturer. Enable coolant-through supply before initiating the cut to prevent chip packing in the flutes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Sizes\u003c\/strong\u003e: 1\/4-18, 3\/8-18\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: 18\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: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.3600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: MT7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: CARMEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B0375D0618NPTF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":67912045953330,"sku":"B0375D0618NPTF","price":420.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ebf65ab39736e2c043d87bb88f196f0_4625f589-3212-4cbe-8819-9122d4eb5ff4.jpg?v=1791225932","url":"https:\/\/voomisupply.com\/products\/carmex-b0375d0618nptf-nptf-thread-mill-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
