Built from M42 cobalt high-speed steel, this tool offers improved heat and wear resistance compared to standard HSS end mills, making it well suited for harder workpiece materials and higher cutting speeds. It features a 1.25-inch mill diameter, a 2.5-inch length of cut, and a 5-inch overall length. The bright, uncoated finish is standard for cobalt tooling and works effectively across a range of general-purpose milling operations. Machinists and tool-and-die professionals are the primary users of this end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers, knee mills, and manual vertical mills where ball-nose geometry is required to produce radius floors, ramp cuts, and sculpted contours. The 2-flute configuration provides adequate chip clearance when cutting softer steels, aluminum alloys, and similar materials. The 1.25-inch shank diameter matches the mill diameter, allowing direct clamping in standard ER or side-lock tool holders of the appropriate bore. Right-hand cutting and right-hand spiral flute direction are standard for conventional and climb milling on typical setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for improved heat resistance and tool life over standard HSS\u003c\/li\u003e\n  \u003cli\u003e1.25-inch mill diameter with matching 1.25-inch shank diameter for direct holder fitment\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length of cut accommodates deeper cavity and profile work\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral geometry promotes chip evacuation in slotting and profiling passes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating degradation concern when re-sharpening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cobalt ball end mill for machining centers and manual mills accepting a 1.25-inch shank diameter end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the tool holder and torque the retention hardware per the holder manufacturer specification. Verify runout with a dial indicator before cutting to protect both the tool and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.83 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 723-1439\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720894218546,"sku":"723-1439","price":237.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35862e9699cc30533af9cd5f88973dfc.jpg?v=1788570629","url":"https:\/\/voomisupply.com\/products\/value-collection-723-1439-ball-end-mill-1-1-4-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
