With 3 flutes and an AlTiN coating, it delivers efficient chip evacuation and thermal resistance during high-speed threading operations. The tool features a 3\/16 inch (0.1875 inch) shank diameter, a 0.1800 inch cutting diameter, and a 1\/2 inch length of cut, making it well-suited for precise thread milling in tight workspaces. Licensed machinists and CNC programmers working in job shops, production facilities, and tool rooms are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is built for use in CNC machining centers performing helical interpolation to produce 1\/4-20 threads at 20 TPI. It handles both internal and external thread profiles in a single tool, reducing tool changes and setup time. At 2.5 inches overall length with a 0.1875 inch shank, it fits standard collet chucks and end mill holders used in vertical and horizontal machining centers. It is appropriate for threading in aluminum, steel, stainless, and other materials where AlTiN coating provides heat and wear resistance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 1\/4-20 internal and external threads in a single tool setup\u003c\/li\u003e\n  \u003cli\u003e3-flute helical design promotes chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e0.1800 inch cutting diameter with 1\/2 inch length of cut for precise thread depth control\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard collet and end mill holder tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with helical interpolation capability, producing 1\/4-20 unified threads at 20 TPI in internal and external configurations using standard collet or end mill holder systems with 3\/16 inch bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified CNC machinists or tooling technicians familiar with helical interpolation programming. Secure the shank fully in a matched collet or end mill holder and verify runout before threading operations. Always confirm spindle speed, feed rate, and helical pitch are programmed per the manufacturer's threading data for this tool diameter and coating. Do not use this tool in manual or non-interpolating equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 20 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.1800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.2500 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: 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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 70044-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728413786418,"sku":"70044-C3","price":233.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5e0d93d2b2efba1e032cec8c5ee367a_7b74620e-3daa-445c-8d01-cd9d40cf40fc.jpg?v=1788690948","url":"https:\/\/voomisupply.com\/products\/harvey-tool-70044-c3-thread-mill-1-4-20-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
