Built from M42 cobalt high-speed steel, this tool delivers heat and wear resistance suited for difficult-to-machine alloys and stainless steels. It features 6 flutes with a 30-degree right-hand spiral helix, providing smooth chip evacuation and stable cutting action. With a 5-inch length of cut and 8.75-inch overall length, this is a full-size end mill intended for production and job-shop environments where reach and rigidity matter. It is centercutting, allowing direct plunge entry without a pre-drilled hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in vertical machining centers and manual knee mills for roughing and finishing passes on ferrous and non-ferrous materials. The 2-inch shank diameter matches standard large-bore toolholders, collet chucks, and end mill holders used in industrial setups. It is uncoated and suited for applications where coolant flood is available and coating is not required. Machinists, tool and die makers, and CNC operators in aerospace, mold and die, and general metalworking shops are the primary users. The regular-length designation makes it appropriate for standard depth-of-cut work without excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat resistance and tool life in tough materials\u003c\/li\u003e\n  \u003cli\u003e6-flute spiral design with 30-degree helix angle for efficient chip flow and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits direct plunge milling without pilot drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle use\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for flood-coolant machining environments\u003c\/li\u003e\n  \u003cli\u003e2-inch shank diameter for secure fit in large-bore toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard 2-inch shank large-bore end mill holders, collet chucks, and Weldon-style holders used on vertical machining centers and manual mills.

Ensure the spindle and toolholder bores are clean and free of chips before seating the shank. Confirm proper axial depth of engagement in the holder before tightening set screws or collet nuts. Never exceed the machine spindle's rated speed or the tool manufacturer's recommended cutting parameters for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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: E299914218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730005393714,"sku":"E299914218","price":700.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/089ad8faf4f700ee555daf60d44df696.jpg?v=1788710035","url":"https:\/\/voomisupply.com\/products\/hertel-e299914218-square-end-mill-2-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
