Built from M42 cobalt high-speed steel and coated with TiCN for added wear resistance and heat tolerance, this tool handles tough ferrous and non-ferrous materials with a coarse pitch flute geometry that clears chips efficiently. The 5\/8 inch diameter, four-flute configuration delivers the rigidity and cutting action needed for roughing passes in manual mills and CNC machining centers. Center-cutting capability allows plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\u003cp\u003eThis end mill suits job shops, maintenance shops, and production environments where roughing cuts on steel, stainless, and alloy materials are routine. The regular length profile fits standard tool holders without extended reach concerns. With a 2.5 inch length of cut and 4.625 inch overall length, it works well in standard R8, CAT, BT, and similar tooling setups where moderate reach and full-diameter engagement are required. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling on most vertical and horizontal mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating extends tool life in abrasive and harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eCoarse pitch roughing geometry reduces cutting forces and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003e5\/8 inch shank diameter matches 5\/8 inch collets and end mill holders directly\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand helix for compatibility with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement roughing end mill for any tooling system accepting a 5\/8 inch straight shank, including R8 collets, ER collets, side-lock holders, and Weldon-style end mill holders.\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 machine in a locked-out, de-energized state per applicable machine tool safety procedures. Use a properly sized collet or end mill holder torqued to the tool holder manufacturer's specification and ensure the shank is fully seated before operation. Inspect the cutting edges for chips or wear before each use. TiCN-coated tools should not be reground without removing the coating first, as partial coating on a reground edge accelerates uneven wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6250 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\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: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5000 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\u003eOverall Length\u003c\/strong\u003e: 4.6250 inches\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\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: 41120650\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748307042610,"sku":"41120650","price":120.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51cc78d5d9a5901695cd6e64e423a7cf.jpg?v=1788892144","url":"https:\/\/voomisupply.com\/products\/hertel-41120650-roughing-end-mill-5-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
