Built from solid carbide and finished with an AlTiN coating, this tool delivers wear resistance and thermal stability in demanding milling operations. With a 0.064-inch cutting diameter and a 0.038-inch neck diameter, it is engineered for fine-pitch, small-diameter thread work where precision and rigidity are critical. CNC machinists and tool-and-die professionals use this mill in both production and prototype applications.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for use in machining centers capable of helical interpolation. It handles both internal thread milling in blind or through holes and external thread profiles on small fastener-scale features. The 1\/8-inch shank diameter makes it compatible with standard collet chucks and small-bore toolholders common in precision machining setups. Applications include aerospace components, medical device parts, and precision instrument housings where fine #2-series threads are specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts #2-56 to #2-64 thread profiles, internal and external, with a single tool\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability in fine-pitch work\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003e0.064-inch cutting diameter with 0.038-inch neck diameter for access in tight geometries\u003c\/li\u003e\n\u003cli\u003e2-flute design balances chip evacuation with edge strength at small diameters\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank fits standard precision collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers with helical interpolation capability.

Ensure the spindle and toolholder are clean and properly torqued before running. Feed rates and spindle speeds should be calculated based on workpiece material and cutting diameter; do not apply drilling or tapping parameters to thread milling operations. Handle solid carbide tooling carefully to avoid chipping the cutting edges during loading 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 #2-64\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 56 to 64\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: 0.064 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.038 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.3125 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54206-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51747774529842,"sku":"54206-C3","price":163.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cde1d1fec4922d086c1506b93d42cb1_fa699030-1b00-44f6-8717-1fe765565694.jpg?v=1788885301","url":"https:\/\/voomisupply.com\/products\/harvey-tool-54206-c3-thread-mill-2-56-to-2-64-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
