Built from submicron-grade carbide with a bright\/uncoated finish, it delivers clean thread forms in a single helical pass. The tool runs a 0.235-inch cutting diameter on a 0.25-inch shank, with a 0.684-inch length of cut and a 2.5-inch overall length. Machinists and tool-and-die professionals use this type of tool on CNC machining centers where a single cutter must handle both thread directions without a tool change.\u003c\/p\u003e\n\u003cp\u003eThis thread mill suits production and job-shop environments running UNF threaded features in steel, aluminum, and similar machinable materials. It is appropriate for applications where thread milling is preferred over tapping, such as blind holes with minimal thread runout, hard materials, or situations requiring the same tool to cut both internal bores and external bosses. The right-hand flute direction and 3-flute geometry support balanced cutting forces and predictable chip evacuation at typical thread milling feeds and speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 5\/16-24 UNF threads at 24 teeth per inch in both internal and external orientations\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003e3-flute, right-hand helical geometry promotes chip flow and balanced radial load\u003c\/li\u003e\n  \u003cli\u003e0.235-inch cutting diameter with 0.684-inch length of cut suits typical 5\/16 thread depths\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish  -  compatible with a wide range of cutting fluids and workpiece materials\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup on standard CNC machining centers\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 accepting a 0.25-inch straight shank, used wherever 5\/16-24 UNF thread milling capability is required in internal or external applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by a qualified machinist on a CNC machining center with helical interpolation capability. Secure the 0.25-inch shank in a precision collet or end mill holder and verify runout before cutting. Always confirm spindle speed, feed rate, and helical pitch are programmed to match the 5\/16-24 UNF thread specification before the first pass. Do not use this tool in a manual drill press or with axial-only feed motion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\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: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.235 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\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.684 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\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: 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: 0.01 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: TM235-24H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51964395913522,"sku":"TM235-24H","price":217.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8e64edc100dbc5b19fa7782c209323d.jpg?v=1789949029","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tm235-24h-thread-mill-5-16-24-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
