Manufactured from high speed steel (HSS) with a bright, uncoated finish, it features a 0.2813-inch cutting diameter and a 0.5625-inch length of cut. The 2-flute, spiral geometry with a 30-degree right-hand helix promotes efficient chip evacuation during machining. With a 3\/8-inch shank diameter and 3.125-inch overall length, this regular-length tool is suited to CNC machining centers, knee mills, and manual milling setups. Machinists and toolroom operators working with aluminum, mild steel, plastics, and similar workpiece materials will find this a dependable general-purpose end mill.\u003c\/p\u003e\n\u003cp\u003eThis ball end mill is appropriate for light-to-medium material removal on ferrous and non-ferrous workpieces in job shop, production, and maintenance machining environments. The double-end configuration provides two usable cutting ends, extending effective tool life before replacement is needed. The right-hand cutting direction and right-hand flute spiral make it compatible with standard spindle rotation on conventional milling equipment. It is well suited to profiling 3D contours, ramp milling, and finishing passes where a spherical nose profile is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool, increasing value per unit\u003c\/li\u003e\n  \u003cli\u003e0.2813-inch (9\/32 inch) ball nose diameter for contouring and profiling operations\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral geometry with 30-degree helix angle promotes chip clearance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction offers toughness and re-sharpenability\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose machining applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter fits standard collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or production ball end mill for use in standard 3\/8-inch collets, ER-style collet chucks, and end mill holders on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool. Seat the shank fully in the collet or holder to the recommended engagement depth and torque the retention system per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates wear and reduces surface finish quality on ball-nose tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2813 inches (9\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5625 inches (9\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/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: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: E211201801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748306583858,"sku":"E211201801","price":50.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ba3c066e350ee3232cafaab2f5f7267.jpg?v=1788892134","url":"https:\/\/voomisupply.com\/products\/hertel-e211201801-ball-end-mill-0-2813-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
