Built from submicron-grade carbide and finished with an AlTiN+ coating, this tool delivers high wear resistance and thermal stability in demanding machining environments. It features 4 right-hand flutes with a 0.5500-inch cutting diameter and a 1.1710-inch length of cut, making it suitable for threading operations that require a single-pass helical interpolation strategy. Machinists and tool-and-die professionals working with NPT pipe thread profiles will find this tool suited to production and maintenance machining contexts.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is configured to produce NPT 1-11-1\/2 and 2-11-1\/2 thread sizes, covering both 1-inch and 2-inch nominal pipe thread diameters in a single tool. The 5\/8-inch shank diameter provides secure clamping in standard ER or side-lock toolholders. With a 4.0000-inch overall length and a minimum nominal diameter of 1.0000 inch, it is appropriate for CNC machining centers performing pipe thread operations on ferrous and non-ferrous materials. This tool is typically used in job shops, maintenance facilities, and production environments where NPT threads are required in fittings, manifolds, and pipe flanges.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide substrate for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating provides elevated heat and oxidation resistance during high-speed threading\u003c\/li\u003e\n  \u003cli\u003eCuts both NPT 1-11-1\/2 and 2-11-1\/2 thread profiles with a single tool\u003c\/li\u003e\n  \u003cli\u003e4 right-hand helical flutes for efficient chip evacuation during interpolation\u003c\/li\u003e\n  \u003cli\u003eInternal and external thread milling capability reduces tooling inventory requirements\u003c\/li\u003e\n  \u003cli\u003e0.5500-inch cutting diameter with 1.1710-inch length of cut supports full thread depth engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CNC machining centers capable of helical interpolation; compatible with NPT 1-11-1\/2 and 2-11-1\/2 thread standards as specified.

Confirm toolholder runout is within acceptable limits before use, as excessive runout will degrade thread quality and tool life. Power down the spindle and follow lockout\/tagout procedures when changing or inspecting the tool. Do not use this tool in manual milling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Sizes\u003c\/strong\u003e: 1-11-1\/2 and 2-11-1\/2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.1710 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN+\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  \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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TMX550-11.5-HA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51996363555122,"sku":"TMX550-11.5-HA","price":390.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb38e221474882878121a853d662afad_e1a3fa19-8794-45f9-9a06-7e192c52a72e.jpg?v=1789993340","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmx550-11-5-ha-helical-thread-mill-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
