Built from solid carbide and coated with TiAlN for heat and wear resistance, this tool delivers consistent thread quality in ferrous and non-ferrous workpiece materials. It features a right-hand flute direction, 3 flutes, and a 0.235-inch cutting diameter with a 0.625-inch length of cut. The 1\/4-inch shank fits standard CNC machining center collets. This tool is used by machinists and toolroom professionals running thread milling operations on CNC mill or machining center equipment.\u003c\/p\u003e\n\u003cp\u003eThe TM31224 suits production and toolroom applications where a single thread mill must handle both internal and external 5\/16-24 thread forms. At 2.5 inches overall length and 24 teeth per inch, it is well-proportioned for reaching threads in shallow-to-moderate depth bores as well as external bosses. Solid carbide construction makes it appropriate for harder workpiece materials and higher spindle speeds compared to HSS alternatives. No coolant-through capability means external flood or mist coolant should be applied at the tool-workpiece interface during the milling cycle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 5\/16-24 UN threads both internally and externally with one tool\u003c\/li\u003e\n  \u003cli\u003eSolid carbide substrate for rigidity and wear life in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves heat resistance and extends tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e3 right-hand helical flutes for smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003e0.235-inch cutting diameter with 0.625-inch length of cut for shallow-to-moderate thread depth\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch shank diameter compatible with standard ER collet toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread milling tool for CNC machining centers capable of helical interpolation with a 1\/4-inch collet or toolholder bore accepting a straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread mills require a CNC control capable of helical interpolation  -  confirm programmed tool path and lead-in move before cutting. Secure the 1\/4-inch shank in a precision collet or end mill holder and verify runout with a dial indicator before the first pass. Power down and lock out the spindle before tool changes or shank inspection. External flood or mist coolant is recommended since this tool does not have through-coolant capability.\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: UN\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: 24\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\u003eCutting Diameter\u003c\/strong\u003e: 0.235 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: 0.625 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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: 0.3 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: ALLIED MACHINE AND ENGINEERING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM31224\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51742387405106,"sku":"TM31224","price":222.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/213e936d6b80d010c2e21f76fe1064ab.jpg?v=1788837134","url":"https:\/\/voomisupply.com\/products\/allied-machine-tm31224-thread-mill-5-16-24-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
