With a 0.4375-inch (7\/16-inch) cutting diameter and a 1-inch length of cut, this single-end tool delivers controlled material removal in contoured surfaces, slots, and profiling passes. The 4-flute geometry provides a balance of chip evacuation and surface finish quality. Manufactured from micrograin solid carbide and finished with a bright, uncoated surface, it is suited for use in rigid setups where cutting geometry and runout control are critical. Machinists and toolroom professionals will find this tool appropriate for general-purpose finishing and semi-finishing work.\u003c\/p\u003e\n\u003cp\u003eThis ball end mill is used in CNC machining centers and manual mills for contouring, 3D profiling, and cavity work in ferrous and non-ferrous materials. The right-hand cut and right-hand flute direction make it compatible with standard spindle configurations found in most vertical machining centers. The 7\/16-inch shank diameter fits standard collet and end mill holder sizes. With a 2.75-inch overall length, this tool is compact enough for work in tighter setups while still providing adequate reach for most general milling tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.4375-inch (7\/16-inch) ball nose cutting diameter for precise contour and profile milling\u003c\/li\u003e\n  \u003cli\u003e1-inch length of cut supports profiling passes with controlled depth engagement\u003c\/li\u003e\n  \u003cli\u003e4-flute design balances chip removal with surface finish performance\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction provides hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suited for applications where coating is not required or preferred\u003c\/li\u003e\n  \u003cli\u003eSingle-end, right-hand cut configuration for use in standard CNC and manual mill spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitute ball end mill for use in standard 7\/16-inch collets and end mill holders on CNC vertical machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard tooling setup procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank to the recommended insertion depth for the holder being used to minimize overhang and reduce deflection risk. Verify runout with a dial indicator before beginning cuts, particularly for finishing operations where tolerances are tight.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single 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\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: 0.128 pounds\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: E5250028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729715888434,"sku":"E5250028","price":78.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07d4032b36b245e3a11bfce029019b22.jpg?v=1788708317","url":"https:\/\/voomisupply.com\/products\/hertel-e5250028-ball-end-mill-0-4375-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
