Manufactured from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting ferrous metals, stainless, and tough alloys. The mill measures 2 inches in diameter with an 8-flute, fine-pitch geometry that produces a smoother surface finish than coarse-pitch roughers while maintaining high chip-load capacity. Overall length is 9.75 inches with a 6-inch length of cut. The bright, uncoated finish makes tool wear easy to monitor during service. This tool is installed by machinists and tool-and-die professionals in vertical or horizontal milling machines.\u003c\/p\u003e\u003cp\u003eThe 84213933 is suited for roughing passes in production and job-shop environments where a large-diameter end mill is required. The 2-inch shank diameter matches the cutter diameter, which is standard for heavy-duty roughing applications on knee mills, CNC machining centers, and similar equipment. Right-hand cutting and right-hand flute direction follow conventional milling orientation. The fine-pitch, 8-flute configuration is best applied at controlled feed rates to manage chip evacuation on deep cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat and wear resistance in tough materials\u003c\/li\u003e\n\u003cli\u003e8-flute fine-pitch geometry balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003e6-inch length of cut accommodates deep-pocket and long-reach milling operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for standard milling machine spindle direction\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish allows direct visual inspection of cutting edge condition\u003c\/li\u003e\n\u003cli\u003eSingle-end design with non-centercutting tip — not intended for plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard milling machine spindles and tool holders accepting a 2-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Secure the shank fully in a collet chuck or end mill holder rated for the shank diameter before operation. This tool is non-centercutting and must not be used for plunge milling — ramp or helical entry is required. Verify spindle speed and feed rate against published data for the workpiece material before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.75 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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\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: 84213933\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747867197746,"sku":"84213933","price":673.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1c535a75ec69a73b0ad07f27e1bfbaf.jpg?v=1788886433","url":"https:\/\/voomisupply.com\/products\/hertel-84213933-roughing-end-mill-2-in-8-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
