Manufactured from M7 high speed steel, it runs uncoated with a spiral flute geometry and a 30-degree helix angle that promotes chip evacuation and cutting stability. The mill diameter is 0.2188 inches (7\/32 inch), the length of cut is 0.625 inches (5\/8 inch), and the overall length is 2.4375 inches (2-7\/16 inch). The 0.375-inch (3\/8 inch) shank fits standard milling chuck and collet holders. Center-cutting geometry allows plunge entry in addition to peripheral cuts. Installed by machinists and tool-and-die technicians on manual mills and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill suits short-to-medium reach milling tasks in job shops, maintenance machining environments, and production settings where HSS tooling is preferred over carbide. The right-hand cut and right-hand spiral flute configuration make it compatible with standard spindle direction on most vertical milling machines. Extended reach is not a feature of this tool, keeping deflection low during slotting and profiling cuts in mild steel, tool steel, aluminum, and similar machinable materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness and re-sharpenability\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids on ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank compatible with common collet and chuck toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use HSS square end mill for standard 3\/8 inch collet and milling chuck toolholders on vertical mills and CNC machining centers.\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 inserting or removing the tool from its holder. Verify collet or chuck torque specifications per the toolholder manufacturer's guidelines before running. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2188 inches (7\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/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: 2.4375 inches (2-7\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: E103901402\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738573635890,"sku":"E103901402","price":29.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fad69ee7e5d8d22ff91526d15a1141b.jpg?v=1788801172","url":"https:\/\/voomisupply.com\/products\/hertel-e103901402-square-end-mill-7-32-inch-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
