Built from micrograin solid carbide and coated with TiAlN, this tool delivers consistent thread geometry and extended tool life in ferrous and non-ferrous materials. It runs 4 flutes with a 0.37-inch cutting diameter and a 1.25-inch length of cut, making it well suited for threading operations where rigid setup and precise thread form are required. Machinists and CNC operators use this tool in place of traditional taps where thread milling is preferred for tool life or tolerance control.\u003c\/p\u003e\u003cp\u003eThis thread mill is used in CNC machining centers for producing 9\/16-18 UNF internal threads. It is appropriate for production and job-shop environments working in steel, stainless steel, aluminum, and similar machinable alloys. The helical flute geometry supports efficient chip evacuation during the threading pass. The 3\/8-inch shank diameter is compatible with standard ER or milling collet systems commonly found on vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9\/16-18 UNF internal thread form with 18 teeth per inch\u003c\/li\u003e\n\u003cli\u003e4-flute helical design for improved chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e0.37-inch cutting diameter with 1.25-inch length of cut\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement — compatible with flood or mist coolant externally\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread milling solution for CNC machining centers equipped with a 3\/8-inch collet or milling chuck, producing 9\/16-18 UNF internal threads in a range of machinable materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread mills are installed and run by qualified CNC machinists or tool-and-die professionals. Ensure the spindle and tool holder are clean and properly torqued before use. Program helical interpolation toolpaths to the correct thread pitch and diameter before running. Always verify workpiece clamping and machine rigidity prior to the threading pass to avoid tool deflection or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-18\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: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.37 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 930-56218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738790101298,"sku":"930-56218","price":398.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df0772b185401e92c7b81c7bab83529f.jpg?v=1788804513","url":"https:\/\/voomisupply.com\/products\/accupro-930-56218-thread-mill-9-16-18-unf-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
