Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention well suited for cutting tough ferrous metals, stainless steel, and high-temperature alloys. The double-end configuration provides two usable cutting ends, extending tool life per unit. At 0.125 inches in diameter with a 0.375-inch length of cut, this end mill handles slotting, profiling, and plunging in tight geometries. A 30-degree helix angle promotes efficient chip evacuation, and the uncoated finish is appropriate for applications where coatings would interfere with tolerances or material compatibility.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills across metalworking shops and maintenance environments. The 0.375-inch shank diameter fits standard collet chucks and end mill holders. Its centercutting capability allows direct plunge entry without a pre-drilled hole, making it versatile for die work, mold work, and general-purpose metal milling. The right-hand cut and right-hand spiral flute configuration is the standard setup for conventional and climb milling on most machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for heat and wear resistance in difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003eDouble-end design with two cutting ends to extend usable tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for compatibility with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable where coating thickness would affect dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or general-purpose cobalt square end mill for use in collet chucks and end mill holders accepting a 0.375-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Torque the collet or set screw to the tool holder manufacturer specification. Confirm runout with a dial indicator before beginning the cut to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0625 inches (3-1\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\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 Style\u003c\/strong\u003e: Double End\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: 0.06 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: E2050008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51750149783858,"sku":"E2050008","price":37.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15b93a63eb242ca22d0ecc76805a57e1.jpg?v=1788913840","url":"https:\/\/voomisupply.com\/products\/hertel-e2050008-square-end-mill-0-125-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
