It is designed to remove large amounts of material quickly in milling operations, using a coarse-pitch flute geometry to break chips and reduce heat buildup. The cutter measures 5\/8 inch in diameter with a matching 5\/8 inch shank and a 5\/8 inch length of cut. Overall length is 2.75 inches. It is center-cutting, allowing plunge entry, and runs in a right-hand cutting, right-hand flute direction. Machinists and tool-and-die professionals use this end mill in CNC and manual milling applications where aggressive stock removal is the priority.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing passes on steel, stainless, and other ferrous and high-temperature alloys where cobalt tooling provides an advantage over standard HSS. The coarse pitch and four-flute configuration make it effective in vertical machining centers, knee mills, and similar setups where chip evacuation and tool rigidity are critical. It is a single-end tool, so once the cutting end is worn, the tool is replaced rather than flipped. The TiAlN coating extends tool life at elevated cutting temperatures, making it a practical choice for dry or semi-dry machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003eCoarse-pitch, 4-flute geometry promotes aggressive stock removal and effective chip breaking\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard milling spindle use\u003c\/li\u003e\n\u003cli\u003eMatched 5\/8 inch shank and cutter diameter for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for 5\/8 inch end mill holders, ER collet chucks, and Weldon-style holders used in CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Secure the shank in a properly sized end mill holder or collet chuck and torque the retention mechanism to the holder manufacturer's specification. Ensure the machine spindle is fully stopped and locked out before changing tooling. Inspect the holder bore and collet for wear or contamination before seating the tool, as a worn holder will reduce runout accuracy and shorten tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.7500 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 (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: Coarse\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: 84511492\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749303648562,"sku":"84511492","price":79.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d83a0522fe18633b3d81c04bcd037040.jpg?v=1788904291","url":"https:\/\/voomisupply.com\/products\/hertel-84511492-roughing-end-mill-5-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
