Built from M42 cobalt high-speed steel, it offers a 5\/64 inch (0.0781 inch) cutting diameter with a 5\/16 inch length of cut and a 3\/8 inch shank diameter. The overall length is 3-1\/16 inches. The double-end design delivers two usable cutting ends, extending tool life and reducing per-cut cost. The 30-degree helix angle and spiral flute geometry promote chip evacuation and smooth cutting action. This tool is centercutting, allowing plunge entry into the workpiece. Machinists and tool-and-die professionals use this end mill in manual and CNC milling applications.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in job shop, production machining, and maintenance-repair environments where cobalt tooling is preferred over carbide for its toughness and resistance to chipping. The uncoated finish makes it a reliable choice for general-purpose milling in steels, stainless steels, and alloy materials. The right-hand cut and right-hand flute configuration is standard for conventional vertical milling machines and CNC machining centers. The regular length classification fits most standard tool holders with a 3\/8 inch collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003e30-degree helix spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard milling machine compatibility\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids in a wide range of ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank replacement end mill for use in 3\/8 inch collets, end mill holders, and compatible CNC or manual milling machine spindles requiring a 5\/64 inch diameter square end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist. Ensure the machine spindle is fully powered down and locked out before changing tooling. Secure the shank fully within the collet or holder to the recommended engagement depth before tightening. Inspect the cutting edges for chips or wear before each use, as damaged tooling can cause workpiece defects or tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/64 inch (0.0781 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/16 inch (0.3125 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\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.504 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: E2050005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748627841330,"sku":"E2050005","price":35.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ea7b06b6589d1e67303bca2ac1a30a6.jpg?v=1788895906","url":"https:\/\/voomisupply.com\/products\/hertel-e2050005-square-end-mill-5-64-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
