Built with a 0.25 inch diameter and a 1.5 inch length of cut, this single-end tool delivers consistent performance in profiling, contouring, and finishing passes. The 4-flute configuration supports efficient chip evacuation while maintaining a strong cutting edge. With a 30-degree helix angle and right-hand cutting and flute direction, it is well suited for general-purpose milling in steel, aluminum, and similar materials. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThis ball end mill is applicable in both manual and CNC milling setups where a 0.25 inch shank is required. The 6 inch overall length provides extended reach for deeper pockets and profiled surfaces without sacrificing rigidity at this diameter. The uncoated solid carbide construction makes it a reliable choice for shops that regrind tooling or prefer uncoated substrates for specific workpiece materials. It is a single-end tool, meaning it is not reversible and should be replaced when the cutting end is worn.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.25 inch cutting diameter with a matching 0.25 inch shank for direct collet or end mill holder fitment\u003c\/li\u003e\n\u003cli\u003e1.5 inch length of cut suitable for profiling and contouring operations\u003c\/li\u003e\n\u003cli\u003e4-flute design balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth cutting action and chip flow\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides hardness and wear resistance over high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eUncoated finish compatible with regrinding services and dry or lubricated cutting conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-application solid carbide ball end mill for standard 0.25 inch collet chucks and end mill holders used in CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Use a properly sized collet or end mill holder that matches the 0.25 inch shank diameter to prevent runout and premature tool wear. Verify tool projection and reach requirements before beginning a cut, and follow applicable shop safety standards for rotating tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: Uncoated\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: 0.15 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: E5062901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752784855346,"sku":"E5062901","price":74.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bfb708d9411d5ca879cedadb8debb0f.jpg?v=1788930312","url":"https:\/\/voomisupply.com\/products\/hertel-e5062901-ball-end-mill-0-25-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
