It measures 7\/16 inches (0.4375 inches) in diameter with a 1-inch length of cut and a 4-1\/8-inch overall length. Manufactured from M7 high speed steel with a bright, uncoated finish, this tool is well suited for shops running lower-speed operations where HSS tooling is preferred over carbide. A 1\/2-inch shank diameter fits standard collet chucks and end mill holders. Installation and use are handled by machinists and CNC or manual mill operators.\u003c\/p\u003e\u003cp\u003eThis end mill is built for right-hand cutting and right-hand flute direction with a 30-degree helix angle and three spiral flutes. The double-end configuration provides two usable cutting ends, extending tool life per unit. It is centercutting, which allows plunge cuts as well as conventional peripheral milling passes. Typical applications include slotting, profiling, and shoulder milling in ferrous and non-ferrous materials. The regular length classification makes it a standard fit for most bridgeport-style and CNC vertical milling setups where reach is not a limiting factor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for durability in general-purpose milling\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with three spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for compatibility with standard mill spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for vertical mills, knee mills, and CNC machining centers accepting a 1\/2-inch straight shank end mill holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using a standard end mill holder or ER-style collet chuck rated for 1\/2-inch shank tooling. Always de-energize and lock out the spindle drive before changing tooling. Verify tool runout with a dial indicator after mounting and before cutting. Follow shop-standard feeds, speeds, and coolant practices for M7 HSS tooling in your specific material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel, M7 Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 inches (4.1250 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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eEnd Configuration\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright, 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: 0.18 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: E1052028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728789831986,"sku":"E1052028","price":68.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e464d7b0cd93152dc16693b668628f8.jpg?v=1788696231","url":"https:\/\/voomisupply.com\/products\/hertel-e1052028-square-end-mill-7-16-in-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
