With a 0.25 inch diameter and a 4-flute, double-end configuration, this tool delivers efficient material removal and smooth surface finishes in both roughing and finishing passes. The ball nose geometry allows contouring, profiling, and 3D surface work that flat-end geometries cannot handle. At 2.5 inches overall length with a 0.5 inch length of cut, it fits standard toolholders and suits a wide range of CNC machining center setups. The bright, uncoated carbide surface is suited to applications where coatings may cause adhesion or where regrinding is planned.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC vertical and horizontal machining centers, manual mills, and toolroom applications. It performs well in contour milling, die and mold work, radius profiling, and finishing passes on ferrous and non-ferrous workpieces. The double-end design provides two usable cutting ends, extending tool life and reducing per-edge tooling cost. Right-hand cutting and right-hand spiral flutes make it compatible with standard spindle rotation and conventional chip evacuation setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBall nose geometry for contouring, 3D profiling, and radius milling\u003c\/li\u003e\n\u003cli\u003e4-flute, double-end design for extended usable tool life per piece\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suited to regrinding and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e0.25 inch shank diameter fits common ER and end mill toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tool for standard CNC and manual milling applications requiring a 0.25 inch ball end mill with a 0.25 inch shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and toolroom personnel following standard CNC tooling procedures. Ensure the machine spindle is fully stopped and the tool change is performed with the machine in a safe, locked-out state before inserting or removing the tool. Torque toolholder set screws or collet nuts to the toolholder specification and verify runout with a dial indicator before beginning cuts. Inspect both cutting ends before use and discard or send for regrinding if chipping or wear is observed.\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: 0.5 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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: E5252016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739995668786,"sku":"E5252016","price":79.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/118d2000130941c73fb8972ce4cec732.jpg?v=1788821260","url":"https:\/\/voomisupply.com\/products\/hertel-e5252016-ball-end-mill-0-25-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
