Built from submicron-grade solid carbide, this tool delivers the rigidity and wear resistance required for precision threading in small-diameter applications. With a cutting diameter of 0.059 inches, a neck diameter of 0.034 inches, and a 3-flute geometry, the SPTM059 is suited for machinists and CNC operators working in tight-tolerance environments where thread quality and tool life both matter.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used in CNC machining centers for small-fastener thread forms, typically in metalworking, aerospace, electronics, and instrumentation applications. Its single-profile design allows one tool to cover a range of thread pitches within the #2 size class, reducing tool-change frequency in production environments. The bright, uncoated finish makes it compatible with a wide range of workpiece materials. Installation and use require a CNC milling machine with appropriate thread-milling software or canned cycle support.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts both internal and external threads from #2-56 to #2-80 (56 to 80 TPI) with a single tool\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for high rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003e3-flute design balances chip evacuation with cutting stability at small diameters\u003c\/li\u003e\n  \u003cli\u003e0.059-inch cutting diameter and 0.034-inch neck diameter enable access in confined bores\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch shank diameter fits standard collets and toolholders commonly found in CNC setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC milling machines equipped with 1\/8-inch collets or compatible toolholders, and suited for thread-milling operations in the #2-56 to #2-80 thread size range on both internal and external thread forms.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread milling requires a CNC machine with helical interpolation capability and a thread-milling cycle configured in the control software. Secure the 1\/8-inch shank in a clean, properly sized collet and verify runout before cutting. Always confirm spindle speed and feed rate are appropriate for the workpiece material and tool diameter before engaging the cut. Handle solid carbide tooling with care  -  avoid contact with hard surfaces during setup to prevent chipping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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)\u003c\/strong\u003e: 56 to 80\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: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\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: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: SPTM059\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52011593597234,"sku":"SPTM059","price":78.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53ab770537d628700425eaa0c9c393ad.jpg?v=1790004772","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm059-thread-mill-56-80-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
