Built from submicron-grade solid carbide and finished with an AlTiN+ coating, this tool delivers heat resistance and edge retention in demanding production environments. With a 0.495-inch cutting diameter, 4 right-hand helical flutes, and a long-reach design, it is suited for threading operations that require precision and tool rigidity in a single-pass or interpolated path. Machinists and CNC programmers in aerospace, oil and gas, and general manufacturing specify this tool for internal thread milling where tap breakage risk must be eliminated.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is configured for internal threading applications on CNC machining centers capable of helical interpolation. The long-reach design accommodates deeper bores or extended-reach setups. With a 1\/2-inch shank diameter and 4-inch overall length, it mounts in standard collet chucks or shrink-fit holders. The 14 TPI pitch and 1.314-inch length of cut make it appropriate for through-hole and blind-hole internal threading in materials where carbide and AlTiN+ coating provide a clear advantage over HSS alternatives, including hardened steels, stainless alloys, and cast iron.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating provides high-temperature oxidation resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e4 right-hand helical flutes for efficient chip evacuation during internal threading\u003c\/li\u003e\n  \u003cli\u003eLong-reach thread mill type for deep-bore and extended-reach applications\u003c\/li\u003e\n  \u003cli\u003e0.495-inch cutting diameter sized for 3\/4-14 UNS internal thread profile\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design  -  suitable for external coolant delivery setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 3\/4-14 UNS internal threads; compatible with standard CNC machining centers equipped with helical interpolation and accepting a 1\/2-inch shank in collet or shrink-fit toolholders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified CNC machinists or tooling engineers. Secure the 1\/2-inch shank in a balanced, runout-minimized holder before use  -  excessive runout will degrade thread quality and shorten tool life. Program the tool path using helical interpolation per the thread pitch and desired thread depth; consult the machine control documentation and tooling manufacturer feeds-and-speeds data for this material and coating combination. Ensure the spindle and axis drives are fully operational and all workholding is secure before initiating the thread milling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-14\u003c\/li\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: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.495 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.314 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 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\u003eThread Mill Type\u003c\/strong\u003e: Long Reach\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\/Finish\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\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: TMI495-14HA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52051928154418,"sku":"TMI495-14HA","price":282.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e6249feda663e7c3263564d2811633f.jpg?v=1790035195","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmi495-14ha-thread-mill-3-4-14","provider":"Voomi Supply","version":"1.0","type":"link"}
