Built from M42 cobalt high-speed steel, it carries a TiN (titanium nitride) coating that extends cutting-edge life under elevated heat conditions. The cutter measures 1\/2 inch in diameter with a 2-inch length of cut and a 4-inch overall length. Four right-hand flutes with a right-hand cutting direction deliver efficient chip evacuation during roughing passes. This tool is installed by machinists and tool-and-die professionals working on manual mills, CNC machining centers, and knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations on ferrous and non-ferrous metals where stock removal rate is the priority over surface finish. The regular-length geometry makes it a practical choice for general-purpose roughing in job shop and production environments. The 1\/2-inch shank diameter fits standard ER collets, end mill holders, and Weldon-style tool holders commonly found in both manual and CNC setups. It is not centercutting and is not intended for plunge entry cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction handles heat and wear better than standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life on ferrous materials\u003c\/li\u003e\n\u003cli\u003e4 right-hand flutes with right-hand cutting direction for standard milling operations\u003c\/li\u003e\n\u003cli\u003e2-inch length of cut suits most roughing pass depths in regular-length applications\u003c\/li\u003e\n\u003cli\u003e1\/2-inch shank matches the cutter diameter, fitting standard tool holders without reduction\u003c\/li\u003e\n\u003cli\u003eSingle-end design with non-centercutting geometry — not suitable for plunge milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit roughing end mill for 1\/2-inch tool holders including ER collet chucks, Weldon shank holders, and hydraulic chucks used on vertical milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Secure the shank to the manufacturer-specified retention torque for the tool holder type in use. Confirm runout at the cutting edge before beginning a cut. This tool is not centercutting — ramp or helical entry should be used rather than direct plunge.\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 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\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\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 End\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0095 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: 02477339\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737786745138,"sku":"02477339","price":77.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b445bffaf24125225031c8058640e43.jpg?v=1788793539","url":"https:\/\/voomisupply.com\/products\/hertel-02477339-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
