Built from submicron carbide and coated with AlTiN+, it handles demanding materials and elevated cutting temperatures in production environments. The tool produces 5\/16-24 UNF internal threads with a 0.234-inch cutting diameter and a 0.6-inch length of cut. A long-reach design and 2.5-inch overall length make it suitable for applications where standard-reach tooling falls short. This mill is installed and run by machinists and CNC programmers working in precision metalworking, aerospace, automotive, and general manufacturing settings.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is intended for internal threading operations on CNC machining centers. The 3-flute, right-hand helical geometry supports stable cutting and consistent thread form. With a 1\/4-inch shank diameter and 2.5-inch overall length, it fits standard ER and set-screw style toolholders commonly used in vertical and horizontal machining centers. The long-reach configuration allows access to threads in deeper bores or stepped features where short-reach tooling cannot reach the full thread depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating provides high heat resistance and extended tool life in dry or semi-dry cutting conditions\u003c\/li\u003e\n  \u003cli\u003e3 right-hand helical flutes for smooth chip evacuation and stable thread form\u003c\/li\u003e\n  \u003cli\u003eLong-reach design with 2.5-inch overall length for deep-bore and stepped-feature applications\u003c\/li\u003e\n  \u003cli\u003eCuts 5\/16-24 UNF internal threads at 24 TPI with a 0.234-inch cutting diameter\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement  -  suitable for external flood coolant or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with standard 1\/4-inch shank toolholders for internal UNF thread milling applications requiring a 5\/16-24 thread form.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or CNC programmers familiar with thread milling cycles. Secure the 1\/4-inch shank in a properly sized, clean toolholder and verify runout before cutting. Program the tool with a helical interpolation thread milling cycle appropriate for the CNC control in use. Do not exceed manufacturer-recommended speeds and feeds for the workpiece material and coating type.\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\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 24\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\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6 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\u003eThread Mill Type\u003c\/strong\u003e: Long Reach\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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: 2.4 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: TMLR234-24A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52041516613938,"sku":"TMLR234-24A","price":142.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64bb42ca8619f2d2a7d680b2195dec1d.jpg?v=1790027774","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmlr234-24a-thread-mill-5-16-24","provider":"Voomi Supply","version":"1.0","type":"link"}
