Built from M7 high speed steel, it carries a 27\/64-inch (0.4219 inch) cutting diameter with a 13\/16-inch (0.8125 inch) length of cut. The 1\/2-inch shank fits standard ER and straight-bore toolholders found on knee mills, CNC machining centers, and manual lathes with milling attachments. Two right-hand spiral flutes at a 30-degree helix angle clear chips efficiently during light-to-medium cuts. The uncoated finish makes it easy to resharpen. At 0.15 pounds, it is a compact tool suited for general-purpose material removal on steel, aluminum, and similar machinable metals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in job shop, maintenance, and production environments where a reliable general-purpose HSS cutter is needed. The centercutting geometry allows direct plunge entry into the workpiece without a pre-drilled hole, which is useful for pocket milling and slot entry. The double-end design provides two usable cutting ends, extending service life before the tool requires resharpening or replacement. Machinists and tool-and-die technicians working on manual or CNC mills are the typical end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27\/64-inch cutting diameter (0.4219 inch decimal equivalent) for precise fractional-size slots and pockets\u003c\/li\u003e\n  \u003cli\u003eM7 high speed steel construction offers good toughness and grindability for general metalworking\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flutes promote chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eUncoated finish simplifies resharpening on standard tool grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or production-stock square end mill for use in standard 1\/2-inch straight-bore or collet-style toolholders on manual and CNC milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Secure the 1\/2-inch shank in a clean, properly sized collet or end mill holder and torque to the toolholder manufacturer's specification before use. Confirm spindle runout is within acceptable limits before beginning a cut. Always power down and lock out the machine spindle before changing or inspecting tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 27\/64 inch (0.4219 inch)\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: 13\/16 inch (0.8125 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inch (3.7500 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\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\u003eWeight\u003c\/strong\u003e: 0.15 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: E1050027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731688456498,"sku":"E1050027","price":67.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cb6e25d1bcdad9eb197f2832ad62323.jpg?v=1788733912","url":"https:\/\/voomisupply.com\/products\/hertel-e1050027-square-end-mill-27-64-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
