Built from submicron-grade solid carbide, this long-reach mill produces 7\/16-20 threads with a cutting diameter of 0.34 inches and a length of cut of 0.8 inches. The three-flute, right-hand helical configuration provides smooth chip evacuation and consistent thread form. With an overall length of 3.5 inches and a 3\/8-inch shank diameter, it fits standard ER and side-lock toolholders used in vertical and horizontal machining centers.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for precision internal threading operations in ferrous and non-ferrous materials where solid carbide tooling is the standard choice. The long-reach body makes it appropriate for threading holes in deep-pocket features or workpieces with extended standoff requirements. At 20 teeth per inch, it is matched to UNF 7\/16-20 thread standards commonly found in automotive, aerospace, and general mechanical assemblies. No coolant-through capability means it relies on flood or mist coolant delivered externally during the cut.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for dimensional stability and tool life\u003c\/li\u003e\n\u003cli\u003e7\/16-20 UNF internal thread profile at 20 TPI\u003c\/li\u003e\n\u003cli\u003eThree helical flutes with right-hand flute direction for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eLong-reach designation accommodates deep-pocket or extended-reach threading setups\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish  -  no coating buildup concerns on close-tolerance thread forms\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank diameter compatible with standard CNC toolholders\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 internal thread milling operations requiring a 7\/16-20 UNF thread form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread milling requires a CNC control with helical interpolation capability  -  confirm machine compatibility before setup. Secure the 3\/8-inch shank in a properly sized, balanced toolholder and verify runout before cutting. Apply appropriate flood or mist coolant externally, as this tool does not have coolant-through channels. Handle solid carbide tooling carefully to avoid edge chipping during setup and storage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\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: 0.34 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\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: Bright\/Uncoated\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: 0.22 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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TMLR340-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51973817532722,"sku":"TMLR340-20","price":166.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccebed62ab2fd390b354a7c343c00acd.jpg?v=1789974640","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmlr340-20-thread-mill-7-16-20","provider":"Voomi Supply","version":"1.0","type":"link"}
