With a 0.2188-inch cutting diameter, 4-flute geometry, and a 0.5-inch length of cut, this tool delivers smooth surface finishes and efficient chip evacuation in tight-tolerance applications. The double-end configuration extends tool life by providing two usable cutting ends. Right-hand cutting and right-hand spiral flute direction are standard on this mill. Uncoated solid carbide construction suits applications where coating compatibility or re-sharpening is a priority. Machinists and tool-room operators use this end mill for contour milling, slotting, and profile work on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThe E5252014 is suited for use in job shops, production machining environments, and tool-and-die operations. Its 0.25-inch shank diameter fits standard ER collet chucks and end mill holders commonly found on vertical machining centers and CNC routers. The 2.5-inch overall length keeps the tool rigid in standard reach applications, minimizing deflection during climb or conventional milling passes. It is appropriate for cutting aluminum, steel, stainless, and similar workpiece materials where a ball-nose profile is required for 3D contouring or radius work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003e4-flute ball-nose geometry for smooth surface finish on contoured profiles\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool, extending usable life\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral suitable for standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish for compatibility with re-sharpening services or coolant-based applications\u003c\/li\u003e\n\u003cli\u003e0.25-inch shank fits common ER and end mill holder tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank ball end mill with a 0.25-inch diameter shank, compatible with ER collet chucks and end mill holders accepting 0.25-inch round shanks on CNC machining centers and manual vertical mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or holder and torque the retention nut to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on small-diameter carbide tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2188 inches (7\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches (1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double End\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 Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: E5252014\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744462700850,"sku":"E5252014","price":77.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a42c6a37110b390398122b20a40a63af.jpg?v=1788856844","url":"https:\/\/voomisupply.com\/products\/hertel-e5252014-ball-end-mill-0-2188-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
