Manufactured from M42 cobalt high-speed steel, it delivers elevated heat and wear resistance compared to standard M2 tooling, making it well-suited for harder workpiece materials and interrupted cuts. The fine-pitch flute geometry reduces chatter and vibration during heavy roughing passes. At 5\/8 inch diameter with a 1-5\/8 inch length of cut and 3-3\/4 inch overall length, this tool fits standard milling chucks and collets without extended-reach toolholders. The bright, uncoated finish is compatible with a wide range of cutting fluids. It is center-cutting, allowing direct plunge entry into the workpiece. Installed by machinists and toolroom operators on vertical and horizontal milling machines and CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in production and toolroom milling operations where roughing passes must remove significant stock quickly before finish machining. The 4-flute, right-hand cut and right-hand helix configuration is standard for general-purpose roughing on steel, alloy steel, stainless, and cast iron. The regular-length body keeps the tool stiff, minimizing deflection in deep-pocket or shoulder-milling applications. It is a practical choice for job shops and maintenance machining environments where one tool needs to handle varied material types across multiple setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction provides superior red hardness and wear resistance over standard M2 end mills\u003c\/li\u003e\n  \u003cli\u003eFine-pitch roughing flutes reduce cutting forces and chatter during heavy stock removal\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge milling without pre-drilled entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand helix for standard milling machine and CNC spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish works with flood coolant, mist, or straight cutting oil\u003c\/li\u003e\n  \u003cli\u003eRegular length body minimizes overhang and deflection in shoulder and pocket milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank roughing end mill with a 5\/8 inch shank diameter, compatible with ER collet chucks, Weldon-style end mill holders, and milling chucks sized for 5\/8 inch tooling on vertical mills, horizontal mills, and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the drawbar or tool-retention system is disengaged before inserting or removing the tool. Seat the shank fully into the holder to the recommended engagement depth per the toolholder manufacturer. Verify runout with a dial indicator before taking the first cut, as excessive runout will accelerate flute wear and reduce surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (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 (M42 HSS)\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: 1-5\/8 inches (1.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: 88245410\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755613520178,"sku":"88245410","price":132.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74ffd8be5f3ae2f3b53bb5961cd53ef7.jpg?v=1788956914","url":"https:\/\/voomisupply.com\/products\/hertel-88245410-roughing-end-mill-5-8-in-4-flute-cobalt-m42","provider":"Voomi Supply","version":"1.0","type":"link"}
