Built from M42 cobalt high-speed steel, this tool delivers heat resistance and edge retention needed for cutting ferrous materials and harder alloys. It features a double-end configuration with 4 spiral flutes and a 30-degree helix angle, providing efficient chip evacuation and stable cutting geometry. With a 1 inch cutting diameter and 1-7\/8 inch length of cut, it handles slotting, side milling, and peripheral milling tasks. The uncoated finish is standard for M42 cobalt tooling. Machinists and tool-and-die professionals are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in manual knee mills, CNC vertical machining centers, and bridgeport-style milling machines running ferrous stock, stainless steel, and similar materials. The double-end design extends tool life by providing two usable cutting ends per tool. The right-hand cut and right-hand flute configuration matches conventional spindle rotation on standard milling equipment. Regular-length classification makes it appropriate for general-purpose milling depths without extended-reach requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for heat and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool, extending service life\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003cli\u003eUncoated finish — no coating buildup risk on close-tolerance cuts\u003c\/li\u003e\n\u003cli\u003eNon-centercutting geometry — suited for peripheral and side milling, not plunge cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for 1 inch straight-shank milling tool holders used in manual and CNC vertical milling machines with right-hand spindle rotation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or toolroom professional should install this end mill into a properly sized collet or end mill holder rated for 1 inch shank diameter. Ensure the machine spindle is fully stopped and the power is locked out before changing tooling. Verify tool runout with a dial indicator after installation to avoid premature edge wear. This tool is non-centercutting and should not be used for direct plunge operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-3\/8 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: Cobalt (M42 HSS)\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 Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\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: E2051064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747718758706,"sku":"E2051064","price":149.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce1aed12f5c77b6475d3efc2d49c1e38.jpg?v=1788884614","url":"https:\/\/voomisupply.com\/products\/hertel-e2051064-square-end-mill-1-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
