With a 0.2188-inch (7\/32-inch) cutting diameter and a 4-flute configuration, this tool delivers smooth finishes and efficient material removal in profiling, contouring, and slotting cuts. The TiN (titanium nitride) coating increases surface hardness and extends tool life compared to uncoated carbide. A 0.625-inch length of cut and a 2.5-inch overall length make it well-suited for light-to-medium depth work in confined geometries. This is a single-end tool with a right-hand cutting and right-hand flute direction.\u003c\/p\u003e\u003cp\u003eThis ball end mill is used in CNC machining centers, manual knee mills, and tool-and-die shops where accurate 3D contour milling is required. It is a strong fit for ferrous and non-ferrous materials where a fine surface finish on curved or radiused profiles is the primary goal. The 1\/4-inch shank diameter fits standard collets and end mill holders commonly found in both vertical and horizontal milling setups. It is typically purchased by machinists, toolmakers, and CNC programmers working in job shops or production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2188-inch (7\/32-inch) ball nose cutting diameter for precise radius profiling\u003c\/li\u003e\n\u003cli\u003e4-flute geometry for improved finish quality and feed-rate capability\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN coating for extended tool life and reduced built-up edge\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand helix for standard spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSingle-end design with a 1\/4-inch shank and 2.5-inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/4-inch collets and end mill holders on CNC machining centers and conventional milling machines requiring a ball nose end mill in the 7\/32-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the machine or toolholder manufacturer guidelines. Inspect the cutting edges for chips or coating damage before use, and confirm runout with a dial indicator when tight tolerances are required.\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: 0.625 inches (5\/8 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\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: 0.06 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: E6250014\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736849187122,"sku":"E6250014","price":51.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/598384f21fd6c91030953ee2366190db.jpg?v=1788781055","url":"https:\/\/voomisupply.com\/products\/hertel-e6250014-ball-end-mill-0-2188-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
