Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention that standard HSS tooling cannot match. The 3\/16 inch cutting diameter pairs with a 7\/16 inch length of cut, a 30-degree spiral helix, and a TiN (titanium nitride) finish that reduces friction and extends tool life. The double-end configuration provides two usable cutting ends, offering additional value per tool. This end mill is installed and operated by machinists and tool-and-die professionals on manual mills and CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and side milling in ferrous and non-ferrous materials where a small-diameter, center-cutting tool is required. The 3\/8 inch shank diameter fits standard collets and end mill holders common to both manual knee mills and CNC vertical machining centers. The right-hand cut and right-hand flute spiral are standard configurations for general-purpose machining. The regular-length geometry keeps the tool stable in short-reach applications where rigidity is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for superior heat and wear resistance versus standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiN finish reduces friction and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip evacuation in spiral flute configuration\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute — standard orientation for general-purpose milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for manual and CNC milling machines accepting a 3\/8 inch shank diameter end mill holder or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist. Secure the shank fully in a clean, properly sized collet or end mill holder and torque the retention mechanism per the machine tool manufacturer's specifications. Inspect the cutting edges and TiN coating for damage before each use — do not run a chipped or worn end mill. Confirm spindle direction matches the right-hand cut orientation of this tool before engaging the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurface Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.065 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: E4050012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755587961138,"sku":"E4050012","price":45.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e47268e70515232c896fa7031f0b50bf.jpg?v=1788956433","url":"https:\/\/voomisupply.com\/products\/hertel-e4050012-square-end-mill-3-16-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
