Manufactured from M42 cobalt high-speed steel and coated with Titanium Nitride (TiN), it delivers elevated heat and wear resistance compared to standard HSS tooling. The cutter measures 7\/8 inch (0.8750 inch) in diameter with a 3\/4 inch (0.7500 inch) shank, a 1-7\/8 inch (1.8750 inch) length of cut, and a 4-1\/8 inch (4.1250 inch) overall length. With 5 coarse-pitch spiral flutes and right-hand cutting and flute direction, this end mill is suited for high-feed roughing passes where chip clearance and tool life are the primary concerns. Licensed machinists and CNC operators install this tooling in vertical and horizontal milling machines.\u003c\/p\u003e\u003cp\u003eThe 62851860 is built for roughing applications in ferrous and non-ferrous metals where stock removal rate takes priority over finish quality. The coarse pitch geometry and center-cutting capability allow plunge entry and peripheral cuts without requiring a pre-drilled start hole. It is appropriate for use in general machining environments, tool rooms, and production shops running steel, stainless, cast iron, and similar alloys. The TiN coating extends tool life in higher-speed cuts where uncoated cobalt would wear prematurely.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved red hardness and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTitanium Nitride (TiN) coating reduces friction and extends tool life at elevated surface speeds\u003c\/li\u003e\n\u003cli\u003e5 coarse-pitch spiral flutes provide efficient chip evacuation during heavy roughing cuts\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, single-end configuration for standard milling spindles\u003c\/li\u003e\n\u003cli\u003e3\/4 inch shank diameter fits common ER and side-lock toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for vertical and horizontal milling machines accepting a 3\/4 inch shank end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the machine in a full stop, powered-off state before inserting or removing tooling. The shank must be fully seated in the toolholder to the minimum engagement depth recommended by the holder manufacturer. Confirm runout with a dial indicator before initiating a cut. Follow applicable machine safety standards and shop PPE requirements when handling and operating rotary cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.8750 inch\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: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inches (1.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Fractional)\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal)\u003c\/strong\u003e: 0.7500 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (Fractional)\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (Decimal)\u003c\/strong\u003e: 4.1250 inches\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: 62851860\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749627167026,"sku":"62851860","price":121.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bba6ec36be64f36065f1e5179c2b0223.jpg?v=1788908524","url":"https:\/\/voomisupply.com\/products\/hertel-62851860-roughing-end-mill-7-8-in-5-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
