Built from M42 cobalt high-speed steel, it delivers added heat and wear resistance compared to standard HSS tooling. The cutter measures 0.75 inches in diameter with a 2.25-inch length of cut, a 0.75-inch shank diameter, and a 4.5-inch overall length. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation, and the centercutting design allows plunge entry. This tool is installed by machinists and CNC operators on vertical and horizontal milling machines.\u003c\/p\u003e\n\u003cp\u003eThe E2080048 falls into the long-series category, making it well suited for applications requiring extended reach beyond standard-length tooling, such as deep-pocket milling, stepped-surface work, and profiling operations where a standard-length end mill cannot access the feature. The 2-flute configuration is particularly effective in softer materials and slotting operations where chip clearance is a priority. Uncoated construction allows for straightforward resharpening by qualified tool grinding shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved heat resistance and tool life in tough alloys\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge and ramping entry\u003c\/li\u003e\n  \u003cli\u003eLong-series length of cut at 2.25 inches for extended-reach applications\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry maximizes chip clearance in slotting and deep-pocket operations\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows resharpening without coating removal concerns\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 3\/4-inch shank square end mills used in standard milling machine collets, end mill holders, and CNC tool holders accepting a 0.75-inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist using an appropriate end mill holder or collet rated for a 0.75-inch shank. Always power down and lock out the spindle drive before changing tooling. Ensure the shank is fully seated and the set screw or collet is torqued per the tool holder manufacturer specification. Inspect the cutter for chips or edge damage before each use, and never exceed the recommended depth-of-cut and feed rate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/4 inches (2.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/2 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: 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: E2080048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732679328050,"sku":"E2080048","price":91.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14641f7af18a772cc186e9d8d645ff1c.jpg?v=1788745663","url":"https:\/\/voomisupply.com\/products\/hertel-e2080048-square-end-mill-3-4-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
