With 4 flutes and a right-hand flute direction, it delivers clean thread forms in ferrous and non-ferrous materials. The cutting diameter measures 0.3700 inches and the length of cut is 1.0790 inches, making it suitable for threading depths typical of standard fastener applications. The EXO coating provides heat and wear resistance, extending tool life in production environments. This tool is installed and operated by machinists and CNC programmers working in job shop or production machining settings.\u003c\/p\u003e\u003cp\u003eThis thread mill is built for long-reach applications under Series 41000, with a 3\/8-inch shank diameter and a minimum nominal thread diameter of 0.5000 inches. It is well suited for CNC machining centers performing UNC thread milling on through-holes and blind holes where tap breakage risk is a concern. Thread milling with this tool allows a single tool to produce threads at various pitches within its range and eliminates the need for rigid tapping cycles. It is appropriate for use in general manufacturing, aerospace component work, mold and die, and fixture fabrication.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability in demanding cuts\u003c\/li\u003e\n\u003cli\u003eEXO coating provides enhanced wear resistance and thermal protection\u003c\/li\u003e\n\u003cli\u003e4-flute helical design for efficient chip evacuation during thread interpolation\u003c\/li\u003e\n\u003cli\u003eLong-reach thread mill type accommodates deeper threading applications\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction compatible with standard CNC climb-milling strategies\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design keeps tool geometry simple for standard coolant delivery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC machining centers capable of helical interpolation; cuts 1\/2-13 UNC threads with a 3\/8-inch straight shank compatible with standard ER or shrink-fit toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread milling requires a CNC control capable of helical interpolation (G02\/G03 with Z-axis motion). Ensure the shank is fully seated and properly torqued in the toolholder before running the program. Verify correct cutting diameter offset is entered in the tool offset table, as thread fit is determined by the radial compensation value. Do not use this tool in manual milling machines or rigid tapping cycles.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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\u003c\/strong\u003e: 13 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.3700 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.0790 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Mill Type\u003c\/strong\u003e: Long Reach\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 41000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.05 inches L x 0.65 inches W x 0.55 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.147 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: 4100004011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737777045810,"sku":"4100004011","price":713.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/882d8ab6dcf9aa824f676425cff53152_d40699c7-56c3-4699-802e-931af68f5a58.jpg?v=1788793466","url":"https:\/\/voomisupply.com\/products\/osg-4100004011-thread-mill-1-2-13-unc-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
