With 3 flutes and 20 teeth per inch, this tool delivers clean, accurate thread forms in a wide range of materials. The 0.1800-inch cutting diameter and 0.5000-inch length of cut make it well suited for threading operations where precision and rigidity are critical. At 2.5000 inches overall length with a 0.1875-inch shank diameter, it mounts easily in standard CNC machining centers and is used by machinists and toolroom professionals working in production or prototype environments.\u003c\/p\u003e\u003cp\u003eThis thread mill is applicable for both internal and external 1\/4-20 thread profiles, with a minimum nominal diameter of 0.2500 inches. It is used in CNC milling applications where a single tool must handle multiple thread directions or where tap breakage is a concern in blind holes. The bright, uncoated finish suits dry or light coolant applications. It does not feature through-tool coolant. Typical users include machinists in job shops, aerospace, and general manufacturing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts internal and external 1\/4-20 threads with one tool\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e3-flute helical design for improved chip evacuation\u003c\/li\u003e\n\u003cli\u003e20 teeth per inch for precise thread form accuracy\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for a broad range of materials\u003c\/li\u003e\n\u003cli\u003e0.1875-inch shank diameter fits standard CNC toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit thread milling tool for CNC machining centers capable of helical interpolation, applicable to any operation requiring 1\/4-20 internal or external thread profiles.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread mills require a CNC machining center with helical interpolation capability. Ensure the toolholder is properly torqued and runout is minimized before threading operations. Program feed rate, stepover, and lead-in according to the machine tool manufacturer and tooling guidelines. Do not use in manual milling operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 20\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\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.2500 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\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51730128863538,"sku":"70044","price":223.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f9cadf986f4419473097841bc37b3ac_e53bb380-d808-4c0d-ba0c-3dbad15b7fcb.jpg?v=1788712204","url":"https:\/\/voomisupply.com\/products\/harvey-tool-70044-thread-mill-1-4-20-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
