It features four right-hand flutes, a TiAlN coating for heat and wear resistance, and coolant-through capability for chip evacuation during deep or tight-tolerance operations. The cutting diameter is 0.37 inches with a length of cut of 0.875 inches and an overall length of 3 inches. This tool is used by CNC machinists and toolroom operators working with ferrous and non-ferrous materials where thread milling is preferred over tapping.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for CNC machining centers running interpolated thread cycles on both through and blind holes. The 9\/16-18 UN thread form supports a range of internal and external thread applications encountered in precision manufacturing, aerospace, and general metalworking. The 3\/8-inch shank diameter fits standard ER and side-lock toolholders common in production environments. Coolant-through design supports higher feed rates and extends tool life when cutting harder materials. A single tool handles both internal and external threads, reducing tooling inventory requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts 9\/16-18 UN threads internally and externally with one tool\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003eCoolant-through design aids chip evacuation and heat control\u003c\/li\u003e\n\u003cli\u003eFour right-hand helical flutes for smooth cutting action\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank diameter fits standard CNC toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation and compatible with standard 3\/8-inch shank toolholding systems for thread milling operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified CNC machinists familiar with thread milling cycles and toolholder setup. Ensure the spindle and coolant system are off before loading the tool into the toolholder, and verify runout with a dial indicator before production use. Follow the machine tool manufacturer guidelines for helical interpolation parameters. Do not use this tool in manual or non-interpolating machines.\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 Standard\u003c\/strong\u003e: UN\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: 18 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.37 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\u003eLength of Cut\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.5 inches L x 1 inch W x 1 inch H\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ALLIED MACHINE AND ENGINEERING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM56218CH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51733098135858,"sku":"TM56218CH","price":360.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20027605bd5f65e33b1ef8d0dc8f80e2.jpg?v=1788751300","url":"https:\/\/voomisupply.com\/products\/allied-machine-tm56218ch-thread-mill-9-16-18-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
