Built from M42 cobalt high-speed steel with a TiAlN coating, this tool handles tough ferrous and stainless materials where standard HSS tooling falls short. The coarse-pitch spiral flute geometry breaks chips efficiently and reduces heat buildup during heavy cuts. With a 5\/8 inch cutting diameter, 2.5 inches length of cut, and 4-5\/8 inches overall length, it fits standard tool holders used on manual mills and CNC machining centers alike. Machinists and tool-and-die professionals reach for this style of end mill when roughing steel, alloy, and hardened materials before finishing passes.\u003c\/p\u003e\u003cp\u003eThis roughing end mill suits shop environments performing heavy stock removal on steel, stainless steel, cast iron, and high-temperature alloys. The 4-flute, right-hand cut and right-hand spiral configuration makes it appropriate for conventional and climb milling on vertical machining centers, knee mills, and similar setups. The center-cutting design allows plunge entry, adding flexibility to the tool path without requiring a pre-drilled start hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction withstands elevated cutting temperatures in tough alloy steels\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life and reduces friction in dry or semi-dry cutting conditions\u003c\/li\u003e\n\u003cli\u003eCoarse-pitch spiral flutes promote aggressive chip evacuation and reduce chatter\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry permits direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eSingle-end design with matched 5\/8 inch shank and cutting diameter for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard addition for 5\/8 inch end mill holders, ER collets, and Weldon-style tool holders on vertical machining centers and manual knee mills requiring a coarse-pitch roughing end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using an appropriate end mill holder or collet system rated for the 5\/8 inch shank diameter. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the tool. Verify runout with a dial indicator after mounting to confirm proper seating. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when securing and testing the tool at operating speed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003ePackage Dimensions\u003c\/strong\u003e: 3.75 x 0.75 x 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 62888755\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729896210738,"sku":"62888755","price":201.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c4c1ab8aa0f6c54c8c5276797a8a4ca_68c3576a-f38e-426c-83a4-13344c3e0d23.jpg?v=1788709758","url":"https:\/\/voomisupply.com\/products\/hertel-62888755-roughing-end-mill-5-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
