Built from M7 high speed steel, this uncoated cutter carries a 5\/8 inch diameter with a matching 5\/8 inch straight shank and a 2 inch length of cut, making it well suited for slotting, side milling, and peripheral milling where extended reach is needed. The 30-degree right-hand spiral flute geometry promotes chip evacuation while maintaining edge stability. Centercutting capability allows the tool to plunge directly into workpiece material without a pre-drilled pilot hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in manual knee mills, CNC vertical machining centers, and bridgeport-style machines across general metalworking, maintenance, and production environments. The long-length classification accommodates setups requiring deeper reach into pockets or workpieces with taller fixturing. It is installed and operated by machinists and toolmakers working to standard shop tolerances. The 4-1\/8 inch overall length provides clearance in most standard tool holders and collet chucks sized for 5\/8 inch shanks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction for toughness in interrupted cuts and general-purpose machining\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flute for efficient chip evacuation in vertical and horizontal milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pilot drilling\u003c\/li\u003e\n  \u003cli\u003eLong-length classification with 2 inch length of cut for deep pocket and extended-reach applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — regrindable and compatible with standard HSS reconditioning services\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for use in standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for milling machines and machining centers accepting 5\/8 inch straight-shank end mills in ER, R8, or equivalent collet systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a locked-out, de-energized state before loading or unloading the tool. Seat the shank fully into the collet or end mill holder and torque the drawbar or retention mechanism per the machine manufacturer specification. Inspect the cutting edges for chips or damage before each use and confirm proper runout with a dial indicator before taking cuts.\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 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches (2.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eMaterial Grade\u003c\/strong\u003e: M7\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\u003eCentercutting\u003c\/strong\u003e: Yes\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: Single End Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: E1080040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753150513458,"sku":"E1080040","price":74.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1b79efbee90f3b94bb83cb63133a88d.jpg?v=1788933290","url":"https:\/\/voomisupply.com\/products\/hertel-e1080040-square-end-mill-5-8-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
