Built from submicron-grade solid carbide and finished with an AlTiN+ coating, this tool handles demanding materials including hardened steels and high-temperature alloys. It features a long-reach configuration with a 3.5-inch overall length and a 1.2-inch length of cut, making it suitable for threading deeper bores where standard-reach tools fall short. The 3\/8-inch shank diameter keeps it compatible with common collet and end mill holders found on most machining centers.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used in precision machining shops, tool rooms, and production environments where clean, accurate internal threads are required. It is suited for threading 7\/16-20 UNF holes in materials such as stainless steel, alloy steel, titanium, and cast iron. The long-reach design is particularly useful for threading recessed or stepped bores. A licensed machinist or CNC operator typically runs this tool in a helical interpolation cycle programmed at the machine controller.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 7\/16-20 UNF internal threads at 20 teeth per inch\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide body for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating improves heat resistance and tool life in ferrous and exotic materials\u003c\/li\u003e\n  \u003cli\u003eLong-reach design with 3.5-inch overall length for deep-bore applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction, three flutes for balanced cutting load\u003c\/li\u003e\n  \u003cli\u003e0.3400-inch cutting diameter with 1.2-inch length of cut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread mill for use in CNC machining centers equipped with helical interpolation capability and standard collet or end mill toolholding accepting a 3\/8-inch shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by a qualified CNC machinist or toolroom professional. Secure the shank firmly in a collet or end mill holder to the full recommended grip length before running the spindle. Program the tool in a helical interpolation cycle specific to the target thread form  -  do not run this tool in a rigid tapping cycle. Verify spindle speed, feed rate, and coolant strategy against the tool manufacturer's recommendations for the workpiece material before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Mill Type\u003c\/strong\u003e: Long Reach\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.3400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.2000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\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\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: 3.2 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: TMLR340-20ELA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51997797777714,"sku":"TMLR340-20ELA","price":175.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e5409cb7a7e2f5e57195c9b47f9fe95.jpg?v=1789994390","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmlr340-20ela-thread-mill-7-16-20","provider":"Voomi Supply","version":"1.0","type":"link"}
