With a 0.495 inch cutting diameter and a 0.972 inch length of cut, this tool generates accurate unified fine threads in ferrous and non-ferrous workpiece materials. The EXO TiAlN coating provides thermal and wear resistance at elevated cutting temperatures, extending tool life in production and job shop environments. Four right-hand flutes deliver consistent chip evacuation and surface finish. Machinists and CNC programmers specify this tool when thread milling is preferred over tapping for blind holes, hard materials, or close-tolerance applications.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for CNC machining centers performing internal thread milling operations on precision components. The 1\/2 inch shank diameter fits standard ER collet chucks and milling tool holders commonly used in vertical and horizontal machining centers. With a 4.0 inch overall length, the tool provides reach for moderate-depth applications while maintaining rigidity. It is appropriate for job shops, aerospace, hydraulic component, and general precision machining work requiring UNF thread forms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 5\/8-18 UNF internal threads with a single helical interpolation pass\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eEXO TiAlN coating for high-temperature wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eFour right-hand flutes promote efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard CNC canned thread-milling cycles\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design — external coolant or mist lubrication applies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CNC machining centers equipped with standard 1\/2 inch collet or milling tool holders; cuts 5\/8-18 UNF internal thread forms per the Unified National Fine thread standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists or CNC programmers on CNC milling equipment. Secure the shank fully in a properly torqued collet or end mill holder before use. Program a helical interpolation cycle matched to the 5\/8-18 UNF thread pitch; verify the canned cycle parameters and tool offset before cutting the first part. Inspect the cutting edges for wear before each production run and replace the tool at the first sign of edge deterioration to avoid thread form deviation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.495 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.945 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\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: EXO TiAlN\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: 0.375 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.25 x 0.75 x 0.75 inches\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4100002111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729779392818,"sku":"4100002111","price":729.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ba3e9a75e982142a82984c2f6b5bdd5.jpg?v=1788709315","url":"https:\/\/voomisupply.com\/products\/osg-4100002111-thread-mill-5-8-18-unf-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
