Built from M42 cobalt high-speed steel, it delivers hardness and heat resistance suited to tough ferrous and non-ferrous materials. The 5\/8 inch diameter cutter features 4 flutes with a 30-degree right-hand helix and a spiral flute form, providing efficient chip evacuation and smooth cutting action. With a 4 inch length of cut and 6.125 inch overall length, this extra-long configuration is the right tool when standard-length end mills cannot reach the floor of deep pockets or tall workpieces. Machinists and tool-and-die professionals install this tool in vertical mills, CNC machining centers, and manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, peripheral milling, and profiling operations in production and job-shop environments. The extra-long length of cut, starting at 2 inches and extending to 4 inches, supports deep-cavity work in molds, dies, and structural components. The bright uncoated finish is appropriate for applications where coating adhesion or heat buildup is not a primary concern. Right-hand cutting direction is standard for conventional CNC and manual milling setups. This tool is not center-cutting, so it is not intended for plunge entry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for heat and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003e4 flutes with 30-degree right-hand spiral helix for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003e4 inch length of cut in an extra-long configuration for deep-pocket work\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch shank diameter matches the cutter diameter for standard collet and end mill holder fitment\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose milling applications\u003c\/li\u003e\n  \u003cli\u003eNot center-cutting — designed for peripheral and slot milling, not plunge operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for standard 5\/8 inch cobalt square end mills used in CNC machining centers and manual milling machines equipped with R8, CAT, or comparable collet and end mill holder systems accepting a 5\/8 inch shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully within the collet or end mill holder to the recommended engagement depth before tightening — insufficient engagement increases deflection and risk of pull-out. Ensure the machine spindle is fully stopped and the machine is locked out before changing tooling. Do not use this tool for plunge cutting, as it is not center-cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 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\u003eLength of Cut\u003c\/strong\u003e: 4 inches (4.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.125 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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\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: E2036040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746644820274,"sku":"E2036040","price":106.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/441b45e3c404e6da59e78cc221c01b17.jpg?v=1788872120","url":"https:\/\/voomisupply.com\/products\/hertel-e2036040-square-end-mill-5-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
