Built from M42 cobalt high-speed steel and coated with TiCN, this tool handles tough ferrous and non-ferrous workpiece materials with improved wear resistance and heat tolerance. It carries a 5\/8-inch mill diameter with four right-hand flutes in a fine-pitch configuration, delivering a balance of chip evacuation and cutting edge strength. The 1.625-inch length of cut and 3.75-inch overall length make it a regular-length tool suited to general-purpose milling setups. Machinists and tool-and-die professionals specify this type of end mill when productivity matters and surface finish is secondary to stock removal rate.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills. Fine-pitch roughing geometry breaks chips into smaller segments, reducing cutting forces and heat buildup compared to standard finishing end mills. The 5\/8-inch shank diameter matches directly to standard 5\/8-inch collets, end mill holders, and Weldon-style tool holders common in production and job-shop environments. Right-hand cut and right-hand flute direction make this a conventional, widely compatible geometry. Center-cutting capability allows plunge entry where fixturing permits. Typical applications include slotting, profiling, and roughing passes on steel, stainless, cast iron, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat and wear resistance compared to M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating extends tool life and reduces built-up edge on harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eFine-pitch roughing flutes break chips aggressively and lower cutting forces\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand helix — conventional geometry compatible with standard holders\u003c\/li\u003e\n\u003cli\u003eSingle-end design; 5\/8-inch shank fits standard collets and end mill holders without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 5\/8-inch shank roughing end mill compatible with 5\/8-inch collet chucks, end mill holders, and Weldon-style side-lock holders used on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the spindle fully stopped and locked out per shop lockout\/tagout procedures. Ensure the holder bore and shank are clean and free of chips or burrs before seating the tool. Verify runout with a dial indicator after clamping to avoid premature edge wear. Follow machine manufacturer torque specifications for drawbar and set-screw tightening — do not use impact tools on fine-thread drawbars.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6250 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 HSS (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: TiCN\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: 1.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.7500 inches\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 41120759\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752656535858,"sku":"41120759","price":88.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b639de70eeea6ced56e9fe344a7ad6a1.jpg?v=1788929581","url":"https:\/\/voomisupply.com\/products\/hertel-41120759-roughing-end-mill-5-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
