Built from submicron-grade carbide and finished with an AlTiN+ coating, this tool delivers hardness and heat resistance suited to demanding machining environments. It features a 0.1390 inch cutting diameter, a 0.4000 inch length of cut, and a 2.5000 inch overall length. With 3 right-hand flutes and a long-reach design, it is suited for CNC machining centers running rigid tapping cycles or helical interpolation routines. Machinists and tool-and-die professionals are the primary installers of this tooling.\u003c\/p\u003e\u003cp\u003eThis thread mill is used for producing internal 10-32 UNF threads in precision components across aerospace, automotive, and general metalworking applications. Its long-reach geometry allows access to recessed or deep-feature thread locations that standard taps cannot reach. The 1\/4 inch shank diameter fits standard ER collets and tool holders common on vertical and horizontal machining centers. It is appropriate for use in steel, stainless steel, aluminum, and other materials compatible with AlTiN+ coated carbide tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid submicron carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating provides elevated heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e3 right-hand helical flutes for efficient chip evacuation during thread milling\u003c\/li\u003e\n\u003cli\u003eLong-reach design allows threading in recessed or hard-to-access features\u003c\/li\u003e\n\u003cli\u003eCuts internal 10-32 UNF threads at 32 teeth per inch\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design  -  suitable for external flood or mist coolant delivery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread mill for internal 10-32 UNF thread applications on CNC machining centers equipped with a 1\/4 inch collet or tool holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread mills of this type are installed by machinists or CNC programmers on machining centers capable of helical interpolation. Ensure the tool holder is properly torqued and the shank is fully seated in the collet before operation. Program the correct helical toolpath for the target thread size and pitch  -  do not use this tool in a straight plunge or conventional tapping cycle. Confirm spindle speed and feed rate are within the tool manufacturer recommendations for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\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: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.1390 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.4000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 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\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\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: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\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: TMLR139-32A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51963983397170,"sku":"TMLR139-32A","price":147.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b3b42b3dd1497cb3e9ab244c1a3e280.jpg?v=1789948758","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmlr139-32a-thread-mill-10-32","provider":"Voomi Supply","version":"1.0","type":"link"}
