It is designed for general-purpose milling operations including slotting, profiling, and peripheral cutting on ferrous and non-ferrous workpiece materials. With a 0.25-inch cutting diameter, a 0.625-inch length of cut, and a 30-degree helix angle, this tool delivers efficient chip evacuation and stable cutting action. The uncoated finish makes it well suited for applications where re-sharpening is a routine part of tool maintenance. Machinists and toolroom operators working in job shops, maintenance departments, or production environments will find this a dependable general-duty cutter.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard milling machines, CNC machining centers, and manual knee mills that accept a 0.375-inch shank. The 3-3\/8-inch overall length places it in the regular-length category, making it appropriate for setups that do not require extended reach. Its centercutting geometry allows direct plunge entry into the workpiece without a pre-drilled hole, which adds setup flexibility. The right-hand cut and right-hand spiral flute configuration is the standard orientation for the majority of vertical milling applications in general metalworking shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design provides two usable cutting ends, extending tool life between replacements\u003c\/li\u003e\n  \u003cli\u003eM7 high speed steel construction offers good toughness and wear resistance for general milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eSpiral flute, right-hand cut and right-hand flute configuration suits standard milling setups\u003c\/li\u003e\n  \u003cli\u003eUncoated finish simplifies re-sharpening and suits shops with in-house grinding capability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock cutter for milling machines and machining centers that accept a 0.375-inch round shank, appropriate for regular-length end mill applications in general metalworking and toolroom use.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician using an appropriate end mill holder, collet chuck, or Weldon-style side-lock holder sized for a 0.375-inch shank. Ensure the machine spindle is fully stopped and the power is locked out before changing or seating the tool. Confirm runout with a dial indicator after clamping before beginning a cut. Follow your machine manufacturer guidelines for feed rate and depth of cut based on workpiece material and rigidity of the setup.\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 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: 3.375 inches (3-3\/8 inches)\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble End\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\u003eLength Type\u003c\/strong\u003e: Regular\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: E1052016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737897828658,"sku":"E1052016","price":50.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c259ad7f6b9129aa3644b4f6ce7f6d18.jpg?v=1788794935","url":"https:\/\/voomisupply.com\/products\/hertel-e1052016-square-end-mill-1-4-in-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
