Manufactured from M7 high speed steel, it features a 0.25-inch cutting diameter, a 2-flute spiral configuration with a 30-degree helix angle, and centercutting capability that allows direct plunge entry into workpieces. The 3\/8-inch shank diameter provides a secure grip in standard collets and end mill holders. This tool is used by machinists and toolroom technicians performing slotting, profiling, and peripheral milling on manual mills and CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThe E1050016 is suited for light to medium material removal in shop and production environments. Its double-end design extends tool life by providing two usable cutting ends before the tool is retired. The right-hand cut and right-hand spiral flute geometry are standard for conventional and climb milling on most vertical milling machines. With a 0.5-inch length of cut and a 3-1\/8-inch overall length, it fits standard toolholding systems without extended-reach adapters. Typical applications include slot milling, step milling, and contour work in steel, aluminum, brass, and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool, extending service life\u003c\/li\u003e\n  \u003cli\u003eM7 high speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge cuts without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — compatible with standard cutting fluids and oils\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — standard orientation for most milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank replacement end mill fitting any toolholder or collet system accepting a 3\/8-inch shank diameter on manual or CNC vertical milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists using a collet chuck or end mill holder rated for the 3\/8-inch shank diameter. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Tighten the collet or set screw to the toolholder manufacturer's specification using the appropriate wrench — do not over-extend the tool beyond the minimum recommended shank engagement length. Verify runout with a dial indicator after seating before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 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: 0.5 inches (1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.5 inches to 0.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 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 Mill Material\u003c\/strong\u003e: High Speed Steel, Grade M7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: E1050016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51751775174962,"sku":"E1050016","price":35.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29f5afc7e3928bc94897bf887f231f04.jpg?v=1788924253","url":"https:\/\/voomisupply.com\/products\/hertel-e1050016-square-end-mill-1-4-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
