Built from submicron-grade solid carbide, it carries an AlTiN+ coating that improves wear resistance and tool life at elevated cutting temperatures. The tool features 3 right-hand flutes, a 0.2350-inch cutting diameter, and a 0.6690-inch length of cut. At 2.5 inches overall length with a 1\/4-inch shank, it fits standard CNC toolholders used in precision machining centers. This tool is installed and operated by CNC machinists and toolroom technicians working to close-tolerance thread specifications.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for job shops, production machining environments, and toolroom applications where a single tool must handle both internal and external UNEF thread profiles at the 5\/16-32 pitch. It performs in materials where solid carbide with AlTiN+ coating provides a clear advantage over HSS tooling, including hardened steels, stainless alloys, and cast iron. The helical flute geometry supports smooth chip evacuation during the thread milling cycle, reducing the risk of re-cutting chips in blind-hole applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts 5\/16-32 UNEF threads  -  handles both internal and external profiles with one tool\u003c\/li\u003e\n\u003cli\u003eSubmicron-grade solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating provides heat and wear resistance in ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003e3 right-hand helical flutes promote chip flow and reduce cutting forces\u003c\/li\u003e\n\u003cli\u003e0.2350-inch cutting diameter with 0.6690-inch length of cut\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design  -  suitable for flood or mist coolant delivery at the machine\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or toolroom-standard thread mill for CNC machining centers requiring a 1\/4-inch straight shank tool capable of producing 5\/16-32 UNEF internal and external threads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by CNC machinists in standard end mill toolholders or collet chucks sized for a 1\/4-inch shank. Confirm runout at the toolholder before beginning a thread milling cycle, as excessive runout directly affects thread quality and tool life. Program the helical interpolation path to match the 5\/16-32 UNEF thread specification using the machine control or CAM software. Handle solid carbide tooling carefully during setup  -  carbide is brittle and susceptible to edge chipping if dropped or impacted against hard surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 and External\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: 0.2350 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: 0.6690 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: 0.2500 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\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\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: TM235-32HA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51975227572530,"sku":"TM235-32HA","price":249.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd0a2b4cf8120ae364324ce0c0fcfff9_529efadd-4346-4acf-b70d-0a9d79a55ced.jpg?v=1789977834","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tm235-32ha-thread-mill-5-16-32","provider":"Voomi Supply","version":"1.0","type":"link"}
