Built from micrograin solid carbide and coated with TiAlN, this tool delivers sharp, consistent thread profiles in a range of ferrous and non-ferrous materials. It carries 4 flutes, a cutting diameter of 0.4950 inches, and a length of cut of 0.8750 inches. With 14 teeth per inch, it is matched to standard 1\/2 inch NPT and 3\/4 inch NPT internal thread forms. This tool is used by machinists and tool-and-die professionals working in CNC machining centers where thread milling is preferred over tapping.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for production and job-shop environments where NPT internal threads are required in materials such as steel, stainless, cast iron, and aluminum. The 1\/2 inch shank diameter fits standard ER or shrink-fit toolholders common on vertical and horizontal machining centers. Typical applications include manifold blocks, hydraulic fittings, pipe ports, and fluid system components requiring pressure-rated NPT thread forms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides heat resistance and extended tool life in dry or minimal-quantity lubrication cutting\u003c\/li\u003e\n\u003cli\u003e4-flute helical design generates internal NPT threads in a single interpolated pass\u003c\/li\u003e\n\u003cli\u003e14 TPI matches standard NPT thread pitch for 1\/2 inch and 3\/4 inch pipe thread sizes\u003c\/li\u003e\n\u003cli\u003e0.4950 inch cutting diameter with 0.8750 inch length of cut for full-depth NPT thread engagement\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup on machines without through-spindle coolant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 1\/2 inch and 3\/4 inch NPT internal threads per standard NPT thread form specifications; fits 1\/2 inch shank toolholders on CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread milling with this tool requires a CNC machining center capable of helical interpolation (simultaneous X, Y, and Z axis movement). Confirm correct toolholder runout before use, as excessive runout will degrade thread quality and accelerate tool wear. Follow the machine tool builder and cutting tool manufacturer guidelines for feed rate, spindle speed, and depth of cut when programming the helical interpolation cycle. Handle carbide tooling carefully to avoid chipping the cutting edges during setup and storage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\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\/2 inch and 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 14 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: 0.4950 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\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: 0.4 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 936-50014\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739909194034,"sku":"936-50014","price":390.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4893509b59851a5a9a9af6c78973b857.jpg?v=1788820275","url":"https:\/\/voomisupply.com\/products\/accupro-936-50014-thread-mill-npt-internal-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
