Built from solid carbide and finished with OSG EXO coating, this tool delivers hard-wearing performance in demanding CNC milling applications. The 3-flute, right-hand design cuts a 5\/16-24 UNF thread profile with a 0.2450 inch cutting diameter and a 0.5000 inch length of cut. At 3.0000 inches overall length with a 1\/4 inch shank, it mounts directly in standard collet chucks and tool holders used in production and job-shop environments. Installation is performed by licensed machinists and CNC programmers.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for machining UNF 5\/16-24 threaded holes in ferrous and non-ferrous workpiece materials where thread milling is preferred over tapping. Typical applications include precision component manufacturing, aerospace, automotive, and general machining where thread quality and tool life are critical. The EXO coating provides enhanced lubricity and wear resistance, making it appropriate for dry or minimal-quantity lubrication (MQL) cutting strategies. It is used in vertical and horizontal machining centers capable of helical interpolation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in thread milling operations\u003c\/li\u003e\n  \u003cli\u003eEXO coating provides improved wear resistance and surface lubricity\u003c\/li\u003e\n  \u003cli\u003e3-flute, right-hand helical design for efficient chip evacuation during thread milling\u003c\/li\u003e\n  \u003cli\u003eCuts 5\/16-24 UNF thread profile at 24 teeth per inch with 0.2450 inch cutting diameter\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank diameter for compatibility with standard collet chucks and end mill holders\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design; suitable for dry or MQL machining setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation; fits standard 1\/4 inch collet chucks and end mill holders.

Secure the shank fully in the tool holder to the recommended grip depth before running; excessive overhang reduces rigidity and thread accuracy. Verify spindle speed, feed rate, and helical pitch parameters in the CAM program before cutting. Always inspect the cutting edges for wear or chipping before each use, as carbide tools can fail suddenly under improper cutting conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.2450 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\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: 0.074 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112806\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: 4100001111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51751166869810,"sku":"4100001111","price":435.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/882d8ab6dcf9aa824f676425cff53152_eb65c02c-ae08-43c5-a56c-6a3d625b7965.jpg?v=1788922013","url":"https:\/\/voomisupply.com\/products\/osg-4100001111-thread-mill-5-16-24-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
