It carries a 3\/8-inch shank diameter and a 0.375-inch cutting diameter, with a length of cut of 0.880 inches and an overall length of 3.0 inches. The four right-hand helical flutes are coated with TiAlN and Titanium Nitride for heat resistance and extended tool life in demanding milling operations. Coolant-through capability allows for effective chip evacuation during deep or high-speed passes. This tool is installed and operated by machinists and CNC tooling professionals working in precision threading applications.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for internal threading operations on CNC machining centers where a single tool must produce a finished 1\/2-20 UNF thread profile. The helical flute geometry makes it effective in materials that generate significant cutting heat or require close tolerance control on thread form. At 20 teeth per inch and a 0.500-inch minimum nominal diameter, it is appropriate for tight-tolerance bores in ferrous and non-ferrous workpieces across aerospace, automotive, and general manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and dimensional stability during thread milling passes\u003c\/li\u003e\n  \u003cli\u003eTiAlN and Titanium Nitride dual coating improves heat resistance and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip flushing in deep or blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eFour right-hand helical flutes deliver smooth cutting action and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eProduces 1\/2-20 UNF internal threads at 20 TPI with a 0.880-inch length of cut\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter compatible with standard ER and milling chuck toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation for internal UNF thread milling; requires a machine with coolant-through spindle capability to take full advantage of the coolant-through feature.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists or CNC setup technicians into a compatible toolholder such as an ER collet chuck or milling chuck sized for a 3\/8-inch shank. Confirm spindle speed, feed rate, and helical interpolation arc radius are programmed correctly for the 1\/2-20 UNF thread form before running the first part. Ensure the machine spindle and coolant system are fully stopped before tool changes. Do not use this tool in a manual drill press or non-interpolating spindle application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\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: 20 TPI\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: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.880 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 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: TiAlN and Titanium Nitride\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: 0.163 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5605120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51740932374834,"sku":"5605120","price":402.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c40aaba5c6518dafe436d12dd28cebc8.jpg?v=1788828442","url":"https:\/\/voomisupply.com\/products\/iscar-5605120-thread-mill-1-2-20-unf-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
