Built from M42 cobalt high-speed steel, this double-end tool delivers durability and heat resistance in demanding applications. It features a 11\/32 inch (0.3438 inch) cutting diameter, a 3\/4 inch length of cut, and a 30-degree helix angle with spiral fluting. The right-hand cut and right-hand flute configuration is standard for conventional milling setups. With four flutes and an uncoated finish, it is suited for a range of ferrous and non-ferrous materials where coating is not required. A licensed machinist or CNC operator typically installs and runs this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical mills, CNC machining centers, and manual knee mills handling steel, stainless, cast iron, and similar materials. The 3\/8 inch shank diameter fits standard ER collets, end mill holders, and Weldon-style tool holders. The regular-length profile and 3-1\/2 inch overall length make it appropriate for general-purpose slotting, profiling, and peripheral milling where extended reach is not required. The double-end design provides two usable cutting ends, extending tool life per unit. Non-centercutting geometry means it is not intended for direct plunge cutting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat and wear resistance versus standard HSS\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle with spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for standard milling operations\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for applications where coating is not specified\u003c\/li\u003e\n  \u003cli\u003eNon-centercutting — not designed for direct plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cobalt square end mill fitting standard 3\/8 inch end mill holders, ER collet chucks, and Weldon-style holders used in vertical mills and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify proper tool holder torque and runout before beginning a cut. Do not use this tool for plunge cutting, as it is non-centercutting geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/32 inch (0.3438 inch)\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: 3\/4 inch (0.7500 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\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\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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\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: 0.504 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: E2051022\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749228806450,"sku":"E2051022","price":64.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54e2098cf6ccd0b611026539d35350e9.jpg?v=1788903374","url":"https:\/\/voomisupply.com\/products\/hertel-e2051022-square-end-mill-11-32-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
