Built from submicron-grade solid carbide and coated with AlTiN+, it delivers the hardness and heat resistance needed for threading ferrous and hardened materials. The tool features a 0.234-inch cutting diameter, a 0.85-inch length of cut, and a 2.5-inch overall length, making it well suited for long-reach threading applications where standard-length tools cannot access a bore. Three right-hand helical flutes provide efficient chip evacuation during the threading pass.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used in precision machining applications requiring UNEF internal threads at 32 teeth per inch. It is intended for use on CNC machining centers where the tool path interpolates the thread form in a single helical pass. Typical applications include aerospace components, hydraulic fittings, instrumentation housings, and other close-tolerance work where UNEF thread forms are specified. The long-reach geometry allows threading in recessed bores or deep features that restrict toolholder clearance. Coolant-through is not supported, so flood or mist coolant applied externally at the cutting zone is the standard approach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide substrate for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating provides high-temperature oxidation resistance and reduced friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eLong-reach thread mill type allows access to recessed bores and deep features\u003c\/li\u003e\n  \u003cli\u003eCuts 5\/16-32 UNEF internal threads with a 0.234-inch cutting diameter\u003c\/li\u003e\n  \u003cli\u003eThree right-hand helical flutes promote chip flow out of the thread form during interpolation\u003c\/li\u003e\n  \u003cli\u003e0.85-inch length of cut accommodates multi-start or full-depth thread engagement in a single pass\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread milling solution for CNC machining centers capable of helical interpolation and programmed to cut 5\/16-32 UNEF internal thread forms.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread mills of this type are installed and torqued into a collet chuck or end mill holder on a CNC machining center by a qualified machinist or tooling technician. Confirm runout at the cutting diameter before production use, as excessive runout accelerates edge wear and degrades thread quality. Program the helical interpolation path to the correct minor diameter and pitch before cutting; verify the program on a test piece before committing to a finished workpiece. Handle solid carbide tooling carefully to avoid edge chipping during setup and storage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\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: 0.234 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.85 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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\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: TMLR234-32ELA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52039211942194,"sku":"TMLR234-32ELA","price":141.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305c4fbd2eb4658f3d438ca09aa54228_70ce84e9-1ea5-47cf-87ed-911a66163096.jpg?v=1790026017","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmlr234-32ela-thread-mill-5-16-32","provider":"Voomi Supply","version":"1.0","type":"link"}
