It produces M4x0.7 threads using a three-flute, right-hand helical geometry that generates clean thread forms in a single helical interpolation pass. The 0.1240-inch cutting diameter and 0.3440-inch length of cut make this tool suited for shallow-to-moderate thread depths in ferrous and non-ferrous materials. The bright uncoated finish is appropriate for applications where coating is not required or where post-process inspection is needed. Coolant-through capability supports chip evacuation and tool life in deeper bores.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used in CNC machining centers performing internal thread milling operations on small-diameter metric fastener holes. Typical applications include precision component manufacturing, mold and die work, and production machining where tap breakage risk must be eliminated. The 3\/16-inch (0.1875-inch) shank diameter fits standard collet chucks and end mill holders commonly found in vertical and horizontal machining centers. The 1.7720-inch overall length provides adequate reach for most standard workpiece configurations without excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts M4x0.7 metric coarse internal threads in a single helical pass\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eThree right-hand helical flutes for balanced cutting forces and smooth thread finish\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design aids chip evacuation and extends tool life in blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for aluminum, brass, and general-purpose machining\u003c\/li\u003e\n  \u003cli\u003e0.1875-inch shank diameter fits standard collet and end mill toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers equipped with helical interpolation capability and standard collet or end mill holders accepting a 0.1875-inch shank diameter. Minimum nominal bore diameter for thread milling is 0.1575 inches (4.00 mm).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread milling requires a CNC control capable of helical interpolation  -  confirm this capability before programming the toolpath. Secure the shank fully in a balanced, runout-controlled collet or end mill holder; excessive runout will degrade thread quality and reduce tool life. Enable coolant-through flow before engaging the cut to ensure proper chip evacuation, particularly in blind holes. Follow the tool manufacturer and machine builder guidelines for feeds, speeds, and depth-of-cut parameters appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4x0.7\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: Metric Coarse\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: 0.1240 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.3440 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.7720 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.1575 inches (4.00 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: Bright\/Uncoated\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: 0.5 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: VARGUS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 80284\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67911334330674,"sku":"80284","price":189.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2079778192a24603011961797e4b0877_905d13bc-91da-457d-b89b-ea115f34758b.jpg?v=1791209810","url":"https:\/\/voomisupply.com\/products\/vargus-80284-helical-flute-thread-mill-m4x0-7-internal","provider":"Voomi Supply","version":"1.0","type":"link"}
