Part of OSG's Series 41000, it features a 0.4300-inch cutting diameter, a 1.0000-inch length of cut, and a 4-flute right-hand flute geometry that supports efficient chip evacuation. The tool carries an EXO coating for improved wear resistance and heat management during threading operations. With a 1\/2-inch shank diameter and a 4.0000-inch overall length, it mounts in standard milling tool holders. This tool is intended for use by machinists and CNC programmers running helical interpolation routines on machining centers.\u003c\/p\u003e\u003cp\u003eThe 4100002011 is suited for production and job shop environments where helical thread milling is preferred over tapping — particularly in harder materials where tap breakage is a concern or where a single tool must produce multiple thread sizes in the same nominal range. The 5\/8-11 UNC thread specification makes it a common choice for fastener holes in structural and mechanical assemblies. With no coolant-through capability, it is best applied with external flood coolant or mist coolant directed at the cutting zone. Minimum nominal diameter for the thread being produced is 0.6250 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in metalcutting applications\u003c\/li\u003e\n\u003cli\u003eEXO coating reduces friction and extends tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e4 right-hand helical flutes promote chip flow and surface finish quality\u003c\/li\u003e\n\u003cli\u003e5\/8-11 UNC thread profile with 11 teeth per inch (TPI)\u003c\/li\u003e\n\u003cli\u003e0.4300-inch cutting diameter with 1.0000-inch length of cut\u003c\/li\u003e\n\u003cli\u003eStandard 1\/2-inch shank diameter fits common milling tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide thread mill for use in CNC machining centers capable of helical interpolation and compatible with standard 1\/2-inch diameter milling tool holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread milling is performed by CNC machinists using helical interpolation cycles on a 3-axis or greater machining center. Power down the spindle and confirm tool holder torque specifications per your machine tool manufacturer before changing tooling. External coolant should be directed at the cutting zone since this tool does not support coolant-through delivery. Confirm workpiece fixturing rigidity before running the helical interpolation pass to avoid deflection-related thread form errors.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.4300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: EXO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 41000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.355 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112806\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4100002011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734721265970,"sku":"4100002011","price":729.94,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/882d8ab6dcf9aa824f676425cff53152_162ad18f-b453-4228-8d34-bd33d383895a.jpg?v=1788765950","url":"https:\/\/voomisupply.com\/products\/osg-4100002011-thread-mill-5-8-11-unc-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
