Built from M42 cobalt high-speed steel, it delivers improved heat resistance and edge retention compared to standard HSS tooling. The 0.750-inch cutting diameter pairs with a 1.625-inch length of cut, making it well-suited for slotting, peripheral milling, and finishing passes where tool life under elevated cutting temperatures matters. The 30-degree helix angle promotes smooth chip evacuation and stable cutting action. This end mill ships uncoated and is centercutting, allowing plunge entry as well as lateral cuts. Licensed machinists and CNC operators in job shops and production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal machining centers, knee mills, and manual milling machines where a 3\/4-inch shank is required. It performs well on carbon steel, alloy steel, stainless steel, and cast iron at appropriate surface footage for cobalt HSS tooling. The regular-length geometry and 3.875-inch overall length make it a standard drop-in choice for general-purpose work without extended-reach clearance requirements. Right-hand cut and right-hand spiral fluting are standard for conventional CNC and manual mill setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for improved heat resistance and tool life\u003c\/li\u003e\n\u003cli\u003e6-flute design increases feed rate capability and improves surface finish on finishing passes\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip evacuation and reduces chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eUncoated finish for use with cutting fluids on a wide range of ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard mill spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tooling for milling machines and machining centers accepting a 3\/4-inch straight shank end mill holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. The shank must be secured in a properly sized end mill holder, collet chuck, or Weldon-style holder torqued to the toolholder manufacturer's specification. Verify spindle direction is set to right-hand rotation before engaging the cut. Always ensure the machine is in a safe, locked-out state when changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches (1-5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.875 inches (3-7\/8 inch)\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\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\u003eExtended Reach\u003c\/strong\u003e: No\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: E2042048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738017988914,"sku":"E2042048","price":107.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3cbe0b1d5f17c0ccc2c16dc51d5d4b7.jpg?v=1788795671","url":"https:\/\/voomisupply.com\/products\/hertel-e2042048-square-end-mill-3-4-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
