Built from submicron-grade carbide and finished with an AlTiN+ coating, this tool handles demanding threading operations in hardened and abrasive materials. It runs a 0.45-inch cutting diameter with a 1.088-inch length of cut, giving machinists sufficient reach for typical thread depths at this pitch. The 0.5-inch shank fits standard ER and side-lock toolholders used on CNC machining centers. Four right-hand helical flutes provide a stable cutting action and efficient chip evacuation throughout the threading cycle.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for CNC machining center work in job shop, production, and toolroom environments. It performs in materials ranging from aluminum and stainless steel to hardened tool steels where the AlTiN+ coating provides thermal protection and extended tool life. Because a single tool cuts both internal and external threads at the 9\/16-16 pitch, it reduces tooling inventory on mixed-operation setups. Typical applications include threaded features in aerospace components, hydraulic manifolds, dies, and general precision machined parts requiring UN-standard threads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts 9\/16-16 UN threads internal and external with one tool\u003c\/li\u003e\n\u003cli\u003eSubmicron-grade solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating for thermal protection in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003eFour right-hand helical flutes for stable cutting and chip evacuation\u003c\/li\u003e\n\u003cli\u003e0.5-inch shank diameter fits standard CNC toolholders\u003c\/li\u003e\n\u003cli\u003eNo coolant-through required  -  compatible with external flood or mist cooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC machining centers with standard 0.5-inch shank toolholding; cuts 9\/16-16 UN-standard threads in internal and external configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread mills are installed and operated exclusively on CNC machining centers using helical interpolation G-code routines  -  this tool is not for use in manual or hand-tapping operations. Verify spindle speed and feed rates in the CAM program before running; incorrect interpolation parameters are the primary cause of thread-form error and tool breakage. Inspect the toolholder collet or chuck for runout before use, as excessive runout accelerates flute wear at this diameter. Follow the machine tool builder and cutting tool manufacturer recommendations for thread milling cycle programming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-16\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: 16 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: 0.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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: 1.088 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\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: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN+\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: 0.5 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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM450-16HA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52063833325874,"sku":"TM450-16HA","price":295.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a593f1ee5653a568fa2bc802bb215e6f.jpg?v=1790043637","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tm450-16ha-thread-mill-9-16-16","provider":"Voomi Supply","version":"1.0","type":"link"}
