Machined from M42 cobalt high-speed steel, this tool delivers improved hardness and heat resistance compared to standard HSS, making it well-suited for cutting harder ferrous and exotic alloy materials. The 11\/64-inch (0.1719-inch) cutting diameter and 7\/16-inch length of cut (LOC) make it a compact, accurate tool for slotting, profiling, and peripheral milling. The double-end design extends tool life by providing two usable cutting ends. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action across a range of materials.\u003c\/p\u003e\u003cp\u003eThis end mill is used in manual knee mills, CNC machining centers, and drill press setups where a small-diameter, short-LOC tool is required. The bright uncoated finish makes it a general-purpose option for shops cutting steel, stainless, cast iron, and similar materials. The double-end configuration is common in production environments where tool changeover time matters. With a 3\/8-inch shank diameter, it seats in standard collet chucks and end mill holders. Machinists, tool-and-die makers, and CNC operators in job shops and production facilities are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends to extend service life\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix for efficient chip evacuation and smooth cutting\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry cuts\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish for general-purpose milling of ferrous and exotic alloys\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or production end mill for applications requiring an 11\/64-inch diameter, 2-flute, double-end cobalt square end mill with a 3\/8-inch shank in standard collet chucks and end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in a collet or end mill holder to the recommended grip length before tightening. Verify runout with a dial indicator before beginning a cut, and confirm feed and speed parameters are appropriate for the workpiece material and machine.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/64 inches (0.1719 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\u003eLength of Cut (LOC)\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-1\/8 inches (3.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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\u003eEnd Configuration\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\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: 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: E2050011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754558783794,"sku":"E2050011","price":46.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/903166a1336e135ef87092c90d988eff.jpg?v=1788946607","url":"https:\/\/voomisupply.com\/products\/hertel-e2050011-square-end-mill-11-64-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
