Built from M42 cobalt high-speed steel, it carries a TiAlN coating that improves heat resistance and extends tool life in ferrous materials. The cutter measures 0.625 inches in diameter with a 2.5-inch length of cut and a 4-5\/8-inch overall length. Four right-hand spiral flutes in a fine-pitch configuration reduce chatter and allow efficient chip evacuation during roughing passes. Center-cutting geometry permits both plunge and peripheral cutting operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations on steel, stainless steel, and other ferrous alloys in job shop, tool room, and production machining environments. It is used in vertical and horizontal milling machines as well as machining centers. The 5\/8-inch shank diameter fits standard R8, CAT, BT, and compatible toolholders. Right-hand cutting direction is standard for conventional CNC and manual mill setups. Machinists and tool-and-die professionals use this tool when high stock removal rates are the priority before finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for improved red hardness over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiAlN coating reduces friction and extends tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eFine-pitch, 4-flute right-hand spiral configuration for controlled chip load during roughing\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e5\/8-inch shank diameter matches the 5\/8-inch cutter diameter for minimal runout\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 2.5-inch length of cut for deep-pocket roughing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit roughing end mill for any milling machine or machining center that accepts a 5\/8-inch straight shank toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Secure the shank fully into a clean, undamaged collet or end mill holder and tighten to the toolholder manufacturer's specified torque procedure before spindle engagement. Inspect the collet bore and shank for chips or debris before mounting. Always bring the spindle to a complete stop before measuring, adjusting workpiece position, or removing the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 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\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\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\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 62850169\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733014348082,"sku":"62850169","price":133.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c4c1ab8aa0f6c54c8c5276797a8a4ca_2b026adc-e626-4559-b0b7-cca0df68d8ae.jpg?v=1788750470","url":"https:\/\/voomisupply.com\/products\/hertel-62850169-roughing-end-mill-5-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
