Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers the heat and wear resistance needed for tougher ferrous and non-ferrous workpiece materials. The cutter measures 0.625 inches in diameter with a 1.625-inch length of cut and a 3.75-inch overall length. Three flutes and a right-hand cutting and flute direction provide efficient chip evacuation during roughing passes. Center-cutting capability allows plunge entry directly into the workpiece. This tool is installed and used by machinists and tool-and-die professionals on manual and CNC milling machines.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing operations on steel, stainless steel, cast iron, and similar materials where high metal removal rates are the priority. The 5\/8-inch shank diameter matches standard milling collets and end mill holders found in most shop environments. It is a single-end tool, meaning the cutting geometry is on one end only. Typical applications include slotting, profiling, and pocket roughing passes prior to a finish cut. The M42 cobalt grade makes it a practical choice when cutting harder alloys or when additional heat resistance is required over standard M2 high-speed steel tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for improved heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eThree right-hand flutes for efficient chip evacuation during heavy roughing cuts\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose roughing applications\u003c\/li\u003e\n  \u003cli\u003eMatching 5\/8-inch mill diameter and shank diameter for straightforward toolholder setup\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with right-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-fitment roughing end mill for use in 5\/8-inch collets, end mill holders, or side-lock holders on manual knee mills and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists using standard end mill holders or collet chucks rated for the 5\/8-inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout at the shank with a dial indicator after seating the tool; excessive runout will reduce tool life and surface finish quality on roughing passes. Follow machine tool manufacturer torque specifications for the holder style in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 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\u003eCoating \/ Finish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\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: 91192187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753466855730,"sku":"91192187","price":79.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/026fbe0cb9e47afe9f4272e762d2f8dc.jpg?v=1788937114","url":"https:\/\/voomisupply.com\/products\/hertel-91192187-roughing-end-mill-5-8-in-3-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
