Built from M42 cobalt high-speed steel, this cutter handles tough ferrous materials and heat-resistant alloys with greater durability than standard HSS tools. It features a TiCN coating that reduces friction and extends tool life in demanding cuts. The mill measures 0.625 inches in diameter with a 2.5-inch length of cut and a 4.625-inch overall length. Four fine-pitch flutes provide efficient chip evacuation while maintaining cutting stability. Right-hand cutting and right-hand flute direction are standard on this configuration.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for production machining environments where stock removal rate is the priority. It is appropriate for use on knee mills, CNC machining centers, and manual milling machines. The center-cutting geometry allows plunge entry as well as conventional peripheral milling. Machinists and toolroom operators working with steel, stainless, and similar materials will find this a reliable workhorse tool for roughing passes before finish milling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for heat and wear resistance beyond standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and improves tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003e4 fine-pitch flutes with right-hand cut and right-hand helix\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRegular length profile: 2.5-inch LOC, 4.625-inch OAL\u003c\/li\u003e\n\u003cli\u003eMatched 0.625-inch shank and cutter diameter for direct collet or end mill holder use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit cutting tool for standard 5\/8-inch end mill holders, collet chucks, and milling machine spindles accepting a 0.625-inch shank diameter.\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 powered down and locked out before changing tooling. Seat the shank fully into the holder and torque set screws or collet nuts per the tool holder manufacturer specification. Inspect the TiCN coating and cutting edges for chips or damage before use; a damaged cutter should not be run.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.625 inches\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\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\u003eCentercutting\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: 41120767\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727145468210,"sku":"41120767","price":120.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04c89d3232c1cd9a7d0bc442753949cb.jpg?v=1788673992","url":"https:\/\/voomisupply.com\/products\/hertel-41120767-roughing-end-mill-5-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
