Built from submicron-grade solid carbide with a bright, uncoated finish, this tool delivers the rigidity and edge retention required for precision thread milling in production and job-shop environments. The 3-flute geometry balances chip evacuation with cutting stability. With a cutting diameter of 0.12 inches and an overall length of 2 inches, this mill suits applications where tight tolerances and clean thread form are non-negotiable. Machinists and CNC operators working in aerospace, medical, and general machining will find this tool well-suited to demanding threading operations.\u003c\/p\u003e\u003cp\u003eThis thread mill is intended for use on CNC machining centers capable of helical interpolation. It handles both internal and external thread profiles across the 8-32 to 8-56 unified thread range, making it a versatile single-tool solution for shops threading small-diameter features. The 3\/16-inch shank diameter fits standard ER collet chucks and other small-bore toolholders. Typical applications include tapped hole production in aluminum, steel, stainless, and similar materials where thread milling is preferred over tapping for improved tool life and thread quality.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts internal and external threads from 8-32 to 8-56 in a single tool\u003c\/li\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003e3-flute design promotes chip evacuation and cutting stability\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eNarrow neck diameter of 0.07 inches allows reach into confined thread features\u003c\/li\u003e\n\u003cli\u003e0.30-inch length of cut and neck length support standard thread depths in this size range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers with helical interpolation capability; fits standard 3\/16-inch bore collet chucks and compatible small-bore toolholding systems for single profile thread milling in the 8-32 to 8-56 thread range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread milling with this tool requires a CNC machining center programmed for helical interpolation  -  confirm the control supports this cycle before setup. Secure the 3\/16-inch shank in a balanced, properly torqued collet chuck to minimize runout. Follow the machine tool builder and tooling manufacturer guidelines for speeds, feeds, and depth-of-cut per pass. Inspect the cutting edge before each use; solid carbide tools are brittle and should not be used if chipping is visible.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size Range\u003c\/strong\u003e: 8-32 to 8-56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI) Range\u003c\/strong\u003e: 32 to 56 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\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: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.07 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.30 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.30 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: SPTM120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51993356206386,"sku":"SPTM120","price":72.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1db6d3e0ca19d0493b64d93a41d799bb.jpg?v=1789991082","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm120-single-profile-thread-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
