It runs 4 right-hand flutes with a TiAlN coating for heat and wear resistance at elevated cutting speeds. The shank diameter measures 0.236 inches and the cutting diameter is also 0.236 inches, giving it a consistent profile from shank to cutting zone. Coolant-through capability helps evacuate chips and manage heat during deep or tight-tolerance thread milling operations. Machinists and tool-and-die professionals use this tool on CNC machining centers where single-point thread milling is preferred over tapping.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for internal thread generation in ferrous and non-ferrous workpiece materials where thread quality and tool life are priorities. At 24 teeth per inch and a 0.625-inch length of cut, it handles standard 5\/16-24 UNF thread depths found in precision mechanical assemblies, aerospace components, and general manufacturing fixtures. The 2.244-inch overall length provides adequate clearance for most standard tool holders and spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides thermal protection and wear resistance at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e4 right-hand helical flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-feed internal thread milling\u003c\/li\u003e\n\u003cli\u003eCuts 5\/16-24 UNF internal threads at 24 TPI\u003c\/li\u003e\n\u003cli\u003eConsistent 0.236-inch shank and cutting diameter for straightforward tool holder setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for CNC machining centers capable of helical interpolation; cuts internal 5\/16-24 UNF threads and is intended as a direct-use or replacement thread mill for applications requiring that thread form and pitch.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC programmers. Secure the shank in a compatible collet or end mill holder rated for the 0.236-inch shank diameter before use. Verify spindle speed, feed rate, and helical interpolation path in the CNC program before engaging the workpiece. Confirm coolant-through supply is active and at adequate pressure prior to initiating the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: 0.236 inches (6.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.236 inches (6.00 mm)\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\u003eShank Length\u003c\/strong\u003e: 1.417 inches (36.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.244 inches (57.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.051 pounds\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: WALTER-PROTOTYP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6580450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67906857435442,"sku":"6580450","price":545.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07422b51f03e6a0a92d43574ce83282a.jpg?v=1791172098","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-6580450-thread-mill-5-16-24-internal-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
