Built from micrograin solid carbide, this tool delivers the rigidity and edge retention required for threading hard and abrasive materials. The cutting diameter is 0.1800 inches with a 0.5000-inch length of cut, and the 1\/4-inch shank provides straightforward mounting in standard toolholders. A TiAlN coating reduces heat buildup and extends tool life during high-speed threading operations. Three flutes provide a balance of chip clearance and cutting stability. This tool is intended for use by machinists and CNC operators working in job shops, production facilities, and toolrooms.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for internal threading applications requiring UNC 1\/4-20 thread form on CNC machining centers and milling machines. It is particularly effective in ferrous and non-ferrous materials where tight thread tolerances and consistent surface finish are required. The helical flute geometry allows thread milling in a single circular interpolation pass, making it a practical choice for both through-hole and blind-hole threading. No coolant-through capability means external coolant or mist is the standard approach for chip evacuation during the cut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for edge retention in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eCuts 1\/4-20 UNC internal threads with 20 TPI\u003c\/li\u003e\n  \u003cli\u003e0.1800-inch cutting diameter with 0.5000-inch length of cut\u003c\/li\u003e\n  \u003cli\u003e3-flute helical design balances chip clearance and cutting stability\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch shank diameter for compatibility with standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread milling solution for CNC machining centers capable of circular interpolation, suitable for producing 1\/4-20 UNC internal threads in workpieces requiring a minimum nominal diameter of 0.2500 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists or CNC operators in a standard end mill toolholder or collet chuck sized for a 1\/4-inch shank. Confirm runout is within acceptable limits before beginning the threading cycle, as excessive runout directly affects thread quality. Spindle and machine power should be off and the tool fully secured before making any adjustments. External coolant or mist is recommended for chip evacuation since this tool does not feature coolant-through capability.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 20 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.1800 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\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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: 0.4 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 930-25020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731881361714,"sku":"930-25020","price":224.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5a9f683dbaeb4e9dcf215c5fe1d7c27.jpg?v=1788736016","url":"https:\/\/voomisupply.com\/products\/accupro-930-25020-thread-mill-1-4-20-internal-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
