Built from M42 cobalt high-speed steel, this double-end tool offers a 9\/32 inch (0.2813 inch) cutting diameter with a 11\/16 inch length of cut and a 30-degree helix angle. The spiral flute geometry promotes efficient chip evacuation and smooth cutting action. With four flutes and a right-hand cut with right-hand flute direction, this end mill is suited for side milling, slotting, and profiling operations on ferrous and non-ferrous materials. The 3\/8 inch shank diameter and 3-3\/8 inch overall length place it in a standard reach configuration used across a wide range of vertical and horizontal milling setups.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for machine shop environments, tool rooms, and maintenance operations where cobalt tooling is preferred over carbide for its toughness and regrindability. The double-end design effectively provides two usable cutting ends, extending tool value in production or job-shop settings. It is used with standard collet chucks, end mill holders, or Weldon-style holders that accept a 3\/8 inch shank. This tool is not center-cutting, so it is not suited for direct plunge operations without a pilot hole or ramping entry strategy.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry with 30-degree helix angle for smooth chip flow and surface finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute orientation — compatible with standard CNC and manual milling machines\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows for straightforward resharpening\u003c\/li\u003e\n  \u003cli\u003eRegular length configuration for rigid setups with minimal overhang\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8 inch end mill holders, collet chucks, or Weldon-flat holders on vertical mills, horizontal mills, and CNC machining centers.

Secure the shank to the rated minimum insertion depth specified by the tool holder manufacturer before tightening. Confirm spindle speed and feed rate are within recommended ranges for cobalt tooling and the workpiece material before engaging the cut. Inspect both cutting ends for chipping or wear before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/32 inch (0.2813 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 11\/16 inch (0.6875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 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\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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End, Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\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\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: E2051018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736505385266,"sku":"E2051018","price":64.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e23899446c9ed473baf00920ab18c5b5.jpg?v=1788778314","url":"https:\/\/voomisupply.com\/products\/hertel-e2051018-square-end-mill-9-32-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
