It features a 0.2031-inch cutting diameter and a 0.625-inch length of cut, making it well suited for profiling, contouring, and 3D surfacing tasks. The tool carries a TiN (titanium nitride) coating that increases surface hardness and reduces friction at the cutting edge, extending tool life in production environments. With a right-hand cutting and right-hand flute direction, it runs on standard CNC machining centers and manual knee mills without special spindle configuration. Machinists and toolroom operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits small-diameter milling applications where a 1\/4-inch shank is required. The 2.5-inch overall length keeps the tool rigid in close-tolerance work while still providing adequate clearance for most fixturing setups. Typical applications include die and mold work, aerospace component finishing, and general precision machining where a ball-nose profile is needed to generate smooth curved surfaces or undercuts. The 2-flute geometry supports chip evacuation in both ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.2031-inch (13\/64 inch) ball nose cutting diameter for fine-detail milling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces tool wear and improves lubricity at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e2-flute design promotes chip clearance in slotting and profiling passes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand helix for use on standard CNC and manual spindles\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with a 1\/4-inch straight shank for common collet and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/4-inch end mill holders, ER collet chucks, and similar toolholding systems on CNC machining centers and manual milling machines requiring a small-diameter solid carbide ball end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism to the toolholder manufacturer's specification. Confirm runout with a dial indicator before beginning a production cut, as excessive runout accelerates wear on small-diameter carbide tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2031 inches (13\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\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: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 0.05 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E699924501\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740335374642,"sku":"E699924501","price":53.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40e11e32b62145fff11ee805bcb1032d.jpg?v=1788824398","url":"https:\/\/voomisupply.com\/products\/hertel-e699924501-ball-end-mill-0-2031-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
