Built from submicron carbide grade material, it delivers the rigidity and wear resistance required for precision threading operations in ferrous and non-ferrous metals. The tool features 4 right-hand flutes, a 0.45 inch cutting diameter, and a 1.0 inch length of cut, making it suitable for through and blind-hole threading where a single-point tap would be impractical or insufficiently rigid. The bright uncoated finish suits a broad range of workpiece materials without coating-compatibility concerns.\u003c\/p\u003e\u003cp\u003eThis thread mill is intended for use in CNC machining centers running helical interpolation cycles. It is applicable in job shop and production environments where 9\/16-12 UNC threaded features are required in components such as structural brackets, mechanical assemblies, and tooling fixtures. The 1\/2 inch shank diameter accommodates standard ER and shrink-fit collet toolholders commonly found in vertical and horizontal machining centers. Internal and external thread capability allows a single tool to address both feature types within the same setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts 9\/16-12 UNC internal and external threads with one tool\u003c\/li\u003e\n\u003cli\u003eSolid submicron carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e4 right-hand helical flutes for improved chip evacuation during threading cycles\u003c\/li\u003e\n\u003cli\u003e0.45 inch cutting diameter with 1.0 inch length of cut for adequate thread engagement depth\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies toolholder selection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation; accepts standard 1\/2 inch collet or shrink-fit toolholders and cuts 9\/16-12 UNC thread forms in both internal and external configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists or CNC tooling technicians. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool from the toolholder. Use proper collet torque procedures per the toolholder manufacturer specifications. Program helical interpolation cycles according to the thread pitch and cutting diameter of the tool; consult the machine control documentation for thread milling cycle parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.0 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\u003eTeeth Per Inch\u003c\/strong\u003e: 12 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\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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: TM 450-12H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51971470885170,"sku":"TM 450-12H","price":304.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28cc712ba9393c6f1d2ba7d6dc1f83a7.jpg?v=1789957701","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tm-450-12h-thread-mill-9-16-12-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
