Built from M42 cobalt high-speed steel and finished with a TiAlN coating, it handles hard and abrasive workpiece materials with extended tool life compared to standard HSS tooling. The coarse-pitch spiral flute geometry breaks chips efficiently and reduces cutting forces during heavy passes. With a 1\/2 inch cutting diameter and 5\/8 inch length of cut, this end mill suits slotting, side milling, and roughing passes where stock removal rate is the priority. Machinists and tool-and-die professionals reach for this geometry when prepping parts for finish passes.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual knee mills across job shop, production, and maintenance environments. The 1\/2 inch shank diameter fits standard R8, ER, and side-lock toolholders common in those setups. Right-hand cut and right-hand flute direction are the conventional configuration for most vertical milling work. The TiAlN coating improves heat resistance, making it a practical choice for dry or minimal-lubrication cutting strategies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved hardness and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in dry cutting and elevated-temperature applications\u003c\/li\u003e\n\u003cli\u003eCoarse pitch, 4-flute spiral geometry promotes efficient chip evacuation during roughing passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard milling setups\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 1\/2 inch shank and 5\/8 inch length of cut\u003c\/li\u003e\n\u003cli\u003eNon-centercutting — plunge milling requires a pre-drilled entry point or ramp entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard 1\/2 inch toolholders on CNC machining centers and manual vertical mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully in the collet or holder and torque the retention hardware to the toolholder manufacturer's specification. Because this end mill is non-centercutting, do not attempt straight plunge entry — use a pilot hole or ramp entry to begin a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\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\u003ePackage Dimensions\u003c\/strong\u003e: 3.75 x 0.75 x 0.75 inches\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: 62852447\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746422554930,"sku":"62852447","price":74.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52d6cb789c0fbe385b67bf7904e6f188_c2689dc6-77b3-48cc-af9f-fa45592d3cd2.jpg?v=1788869936","url":"https:\/\/voomisupply.com\/products\/hertel-62852447-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
