With 6 right-hand flutes and a TiAlN coating, this tool delivers clean thread profiles in demanding materials while managing heat and wear effectively. The cutting diameter measures 0.551 inches, matching the 0.551-inch shank diameter, and the length of cut is 1.125 inches. Overall length is 3.465 inches. Coolant-through capability supports chip evacuation during deep or interrupted thread-milling operations. This tool is intended for use by machinists and CNC programmers working in precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for machining internal UNF 3\/4-16 threads in applications where a single-point or tap approach is not preferred or practical. Helical interpolation on a CNC machining center is the standard method of use. The 6-flute geometry improves feed rates and surface finish compared to fewer-flute designs. The TiAlN coating makes this tool appropriate for dry or near-dry cutting in ferrous and hard materials. Typical applications include aerospace components, hydraulic manifolds, and precision mechanical assemblies where thread quality and positional accuracy are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard or abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e6 right-hand helical flutes improve chip load distribution and thread surface finish\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip flushing in deep-thread applications\u003c\/li\u003e\n\u003cli\u003eCuts internal UNF 3\/4-16 threads via CNC helical interpolation, reducing the need for rigid tapping\u003c\/li\u003e\n\u003cli\u003eMatched cutting and shank diameter of 0.551 inches simplifies tool setup and holder selection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for machining internal UNF 3\/4-16 threads on CNC machining centers capable of helical interpolation; requires a standard tool holder accepting a 0.551-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists or CNC programmers on 3-axis or greater CNC machining centers. Secure the shank in a collet or end-mill holder rated for the 0.551-inch diameter before operation. Verify spindle speed, feed rate, and helical pitch programming against the manufacturer cutting data before running the first part. Enable coolant-through flow at the recommended pressure for the workpiece material to promote chip evacuation and prevent recutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\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\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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: 0.551 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.551 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.772 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.465 inches\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\u003ePackage Weight\u003c\/strong\u003e: 0.399 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: 6580447\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67913866608946,"sku":"6580447","price":1332.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3a53bfa3a72b746152f937fd94db6476_36d8aa49-5688-44ff-a6cc-c6a8a63c0190.jpg?v=1791246783","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-6580447-thread-mill-3-4-16-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
