Built from M42 cobalt high-speed steel, it delivers heat and wear resistance that extends tool life in demanding cuts. The cutter measures 1.25 inches in diameter with a 3-inch length of cut and a 5.5-inch overall length. With 2 flutes and a 30-degree right-hand spiral helix, it promotes efficient chip evacuation and smooth cutting action. The center-cutting geometry allows plunge entry as well as peripheral milling, making it a versatile choice for machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard milling machine setups, CNC machining centers, and manual knee mills where a 1.25-inch shank is accommodated. The long series length of cut at 3 inches makes it well suited for slotting, profiling, and side milling in deeper pockets where a standard-length tool cannot reach. It is appropriate for steels, stainless, and high-temperature alloys commonly encountered in production and job-shop environments. The uncoated finish keeps the tool at a lower cost point for general-purpose work where a specialized coating is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for heat and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003e1.25-inch diameter with matching 1.25-inch shank for direct collet or end mill holder mounting\u003c\/li\u003e\n  \u003cli\u003e3-inch length of cut supports deep-pocket and long-reach milling operations\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design with 30-degree helix for efficient chip clearance\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capability allows plunge milling without a pre-drilled start hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — compatible with standard spindle direction\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for general-purpose ferrous and non-ferrous milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for milling machines and machining centers that accept a 1.25-inch straight shank end mill holder or collet chuck.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and locked before mounting or removing the tool. Seat the shank fully in the holder and torque the set screws or collet nut to the machine manufacturer's specification before engaging the cut. Verify runout with a dial indicator after mounting to minimize premature tool wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\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: 1.46 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: E2080116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748293673266,"sku":"E2080116","price":281.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca91b871e15aad926a48a5a5e15edb60.jpg?v=1788891895","url":"https:\/\/voomisupply.com\/products\/hertel-e2080116-square-end-mill-1-25in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
