Built from M42 cobalt high-speed steel with a TiCN coating, it delivers extended tool life in ferrous and hard materials. The 7\/8-inch diameter cutter features 5 spiral flutes in a fine-pitch configuration with right-hand cutting and right-hand flute direction. It is center-cutting, allowing plunge entry into workpieces. Machinists and tool-and-die professionals install this tool in CNC machining centers and manual mills for roughing passes where stock removal rate and edge durability are the primary requirements.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing applications in job shops, manufacturing facilities, and maintenance machining environments. The 7\/8-inch length of cut and 3.125-inch overall length make it appropriate for moderate-depth pocketing and profiling work. The TiCN coating reduces friction and improves wear resistance compared to uncoated cobalt tooling, making it a practical choice when machining alloy steels, tool steels, and similar materials where heat generation is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for toughness and heat resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces wear and extends tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e5 spiral flutes in a fine-pitch layout for smooth chip evacuation during roughing\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC and manual mill spindles\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 7\/8-inch shank 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 standard-shank roughing end mill compatible with 7\/8-inch end mill holders, collet chucks, and Weldon-style holders used on vertical machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists. Power down and lock out the spindle before mounting or removing the tool. Seat the shank fully in the holder and torque the set screw or collet nut to the holder manufacturer's specification. Inspect the cutting edges and coating for chips or damage before each use, and confirm runout with a dial indicator when precision is required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/8 inches (0.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inches (0.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 inches (3.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/8 inches (0.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Type\u003c\/strong\u003e: Single End\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: 0.5 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: 62848684\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729335091506,"sku":"62848684","price":155.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00a07327d82a5d89557b86da96dbfcae.jpg?v=1788703091","url":"https:\/\/voomisupply.com\/products\/hertel-62848684-roughing-end-mill-7-8-in-5-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
