Manufactured from M7 high speed steel, it features a 5\/16 inch cutting diameter, a 3\/4 inch length of cut, and a 3\/8 inch shank diameter for compatibility with standard collet and end mill holders. The 30-degree spiral flute geometry promotes efficient chip evacuation, while the right-hand cut and right-hand flute configuration suits the majority of vertical and horizontal milling setups. Four flutes provide a balance of chip clearance and surface finish in ferrous and non-ferrous materials. The uncoated finish keeps resharpening straightforward.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slot milling, peripheral milling, and light profiling operations on CNC machining centers, manual knee mills, and benchtop milling machines. The regular-length geometry makes it appropriate for general production work where extended reach is not required. The double-end design allows both cutting ends to be used, extending tool life between replacements. It is a common choice for job shops, maintenance departments, and toolrooms working with steel, aluminum, brass, and similar materials at conventional cutting speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction for durability in general-purpose metal removal\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle with spiral flute promotes chip evacuation and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eFour flutes balance material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard milling machine spindle direction\u003c\/li\u003e\n  \u003cli\u003eUncoated finish simplifies resharpening and regrinding in the field\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct drop-in for standard 3\/8 inch shank end mill holders and collet chucks used in vertical milling machines and CNC machining centers requiring a 5\/16 inch square end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before changing tooling. Seat the shank fully in the collet or end mill holder and torque the retention hardware to the machine manufacturer specifications. Confirm runout with a dial indicator before beginning a production cut. Note that this tool is not centercutting and is not intended for direct plunge entry into solid material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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: 0.08 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: E1051020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732371702066,"sku":"E1051020","price":37.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc5b8243b9dbe77662a3541b6d4db7d5.jpg?v=1788742181","url":"https:\/\/voomisupply.com\/products\/hertel-e1051020-square-end-mill-5-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
