Built from submicron-grade solid carbide and finished with an AlTiN+ coating, this tool delivers consistent thread geometry in a compact form factor suited to small-diameter, fine-pitch applications. The cutting diameter measures 0.059 inches with a 1\/8-inch shank and a 1.5-inch overall length. With 3 flutes and a 0.200-inch length of cut, it is used in CNC machining centers where thread milling is preferred over tapping for precision, tool life, or material considerations.\u003c\/p\u003e\u003cp\u003eThis thread mill is intended for use in machining operations requiring fine-pitch threads in the number-2 screw size range. Its ability to produce both internal and external threads with a single tool makes it practical for job shops, production environments, and tool rooms working with small fastener features. The 0.034-inch neck diameter and 0.200-inch neck length allow access into shallow-boss and close-tolerance features. Machinists working in aerospace, medical device, electronics, and general precision manufacturing will find this tool appropriate for ferrous and non-ferrous materials where the AlTiN+ coating provides thermal resistance and extended edge life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts internal and external threads from 2-56 to 2-80 with a single tool\u003c\/li\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating provides high-temperature resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e0.059-inch cutting diameter with 0.034-inch neck for access in tight features\u003c\/li\u003e\n\u003cli\u003e3-flute geometry for balanced cutting action at fine pitch\u003c\/li\u003e\n\u003cli\u003eCompact 1.5-inch OAL fits standard CNC tool holders with 1\/8-inch shank collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and mill-turn equipment accepting 1\/8-inch shank tooling; suitable for thread milling operations in the 2-56 to 2-80 thread size range on internal and external features.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread milling requires a CNC control capable of helical interpolation; confirm the machine program uses the correct thread milling cycle before running. Secure the shank fully in a collet chuck or high-precision holder to minimize runout, which is critical at this diameter. Use manufacturer-recommended speeds and feeds for the workpiece material and reduce cutting parameters when first qualifying a new program. Inspect the cutting edge under magnification before and after use to detect chipping that may not be visible to the naked eye.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size Range\u003c\/strong\u003e: 2-56 to 2-80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (Min)\u003c\/strong\u003e: 56 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (Max)\u003c\/strong\u003e: 80 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\u003eCutting Diameter\u003c\/strong\u003e: 0.059 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.034 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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\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: SPTM059LA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52108865995058,"sku":"SPTM059LA","price":80.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d49192c0963472c96d01f44316d082c3.jpg?v=1790075177","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm059la-thread-mill-56-80-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
