Built from submicron-grade solid carbide with a bright, uncoated finish, this tool delivers consistent thread geometry in small-diameter applications. The 0.059-inch cutting diameter and 0.034-inch neck diameter allow access to tight bores and confined features. Three helical flutes promote chip evacuation and reduce cutting forces. Machinists and CNC programmers working on precision components, medical parts, electronics hardware, and instrumentation will find this tool suited for small fastener thread production in a single helical interpolation pass.\u003c\/p\u003e\u003cp\u003eThis thread mill is used in CNC machining centers capable of helical interpolation. Its compact geometry makes it appropriate for threading small holes and external bosses where tap breakage is a concern and thread quality must be controlled. The 1\/8-inch shank diameter is compatible with standard collet systems and small-bore tool holders. Both internal and external thread forms are achievable with a single tool, reducing changeover time in mixed-thread jobs. It is commonly used in job shops, aerospace component shops, and precision medical device manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts both internal and external threads from 2-56 to 2-80 in a single tool\u003c\/li\u003e\n\u003cli\u003eSubmicron-grade solid carbide blank for wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e0.059-inch cutting diameter for small-bore and tight-clearance thread applications\u003c\/li\u003e\n\u003cli\u003e3-flute geometry supports chip evacuation in blind and through holes\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eSingle profile design allows thread pitch adjustment via CNC program  -  no tool change required between pitches in 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 and standard 1\/8-inch collet or tool holder systems for single profile thread milling in the 2-56 to 2-80 thread size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread milling requires a CNC control that supports helical interpolation  -  confirm G-code capability before programming. Secure the 1\/8-inch shank in a properly sized, clean collet to minimize runout, which directly affects thread quality at this diameter. Feed and speed parameters should be established from the manufacturer cutting data for the specific workpiece material. Handle solid carbide tooling carefully to avoid chipping the cutting edges during setup and storage.\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 (TPI) Range\u003c\/strong\u003e: 56 to 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: 0.165 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.165 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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\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: SPTM059ML\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52047595995442,"sku":"SPTM059ML","price":75.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a827fd368298f155b67b231596d99c1e_f7e647ad-ca4b-48e0-bf69-d5bfc0719450.jpg?v=1790032045","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm059ml-thread-mill-56-80-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
