Built on the MTEC-NPT series platform, this mini thread mill features a TiAlN coating for extended tool life in ferrous and hardened materials. The 3-flute right-hand helical geometry produces clean thread forms in a single helical interpolation pass. With a 0.2500-inch cutting diameter and 0.3900-inch length of cut, this tool is sized for tight-clearance bores and small-diameter NPT port threading operations. Machinists, tool and die makers, and CNC programmers in precision machining environments install and run this tool.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for machining NPT pipe thread features in production and job-shop environments on CNC machining centers with helical interpolation capability. The mini form factor makes it appropriate for components with limited access or closely spaced features. It covers both 1\/16-inch and 1\/8-inch NPT thread sizes with a single tool, reducing tooling inventory for shops producing fluid-system components, manifolds, fittings, and hydraulic blocks requiring NPT ports.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in material grade IN2005 for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in ferrous, stainless, and hardened workpiece materials\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand helical flute design for efficient chip evacuation and smooth thread form\u003c\/li\u003e\n\u003cli\u003eCuts both 1\/16-inch and 1\/8-inch NPT thread sizes with one tool\u003c\/li\u003e\n\u003cli\u003e27 teeth per inch pitch matched to NPT thread standard requirements\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 0.2500 inches for standard collet or end mill holder clamping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation for cutting NPT internal pipe threads in the 1\/16-inch and 1\/8-inch size range, per the MTEC-NPT series specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread mills require CNC control support for helical interpolation cycles  -  confirm G-code capability before programming. Secure the straight shank in a high-precision collet chuck or end mill holder with adequate gripping length to minimize runout. Ensure the spindle and coolant system are configured per the machine tool builder recommendations before starting the cut; this tool does not include through-tool coolant. Follow the tooling manufacturer feed and speed tables for the specific workpiece material and do not exceed the rated cutting diameter during interpolation setup.\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\u003eMaterial Grade\u003c\/strong\u003e: IN2005\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MTEC-NPT\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\/16 inch and 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Mill Type\u003c\/strong\u003e: Mini\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 27\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\u003eCutting Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.3900 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.3900 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.1100 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\u003eCoating\/Finish\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2946018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52125753246002,"sku":"2946018","price":329.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9ab535fb88371312e0ee79999c2fe4f.jpg?v=1790087839","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-2946018-helical-flute-thread-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
