Built from M42 cobalt high-speed steel and finished with a TiAlN coating, this tool handles tough ferrous and exotic alloy workpieces. The coarse-pitch, 4-flute geometry creates a chip-breaking action that reduces cutting forces and heat buildup during heavy roughing passes. The 3\/8 inch diameter and 3\/8 inch length of cut make it well suited for slotting, profiling, and pocketing operations where material removal rate matters more than surface finish. Installation and use require a compatible end mill holder or collet chuck on a vertical or horizontal milling machine.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in machine shop environments, toolrooms, and production floor settings. The right-hand cutting and right-hand flute direction are standard for conventional CNC and manual milling machines. The TiAlN coating provides thermal resistance, extending tool life in dry or minimal-lubrication cutting conditions. The coarse pitch is particularly effective when roughing stainless steel, tool steel, titanium, and other difficult-to-machine alloys where chip evacuation is critical. It is a single-piece, single-end tool packaged individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in dry and hard-material cutting\u003c\/li\u003e\n\u003cli\u003eCoarse-pitch flute geometry reduces cutting forces during heavy roughing\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for use on standard milling equipment\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 3\/8 inch shank for direct chuck mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for 3\/8 inch end mill holders, collet chucks, and milling fixtures requiring a 3\/8 inch shank roughing end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the end mill. Torque the set screw or collet nut according to the tool holder manufacturer specifications. Confirm runout with a dial indicator before beginning cuts, as excessive runout accelerates edge wear on roughing geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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\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: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/32 inches (2.1562 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\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: 84511468\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736886247730,"sku":"84511468","price":48.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4192d6ef1aabdbb98e5a30815c4b5cbe.jpg?v=1788781542","url":"https:\/\/voomisupply.com\/products\/hertel-84511468-roughing-end-mill-3-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
