Built from M42 cobalt high-speed steel and finished with a TiAlN coating, this tool handles heat and wear better than standard HSS cutters. It features a 1\/2 inch cutting diameter, 4 spiral flutes with a coarse pitch, and a 2 inch length of cut. The right-hand cutting and right-hand flute direction make it compatible with conventional vertical and horizontal milling setups. Machinists and tool-and-die professionals use it for roughing passes on ferrous and difficult-to-machine alloys where material removal rate matters most.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations on machining centers, knee mills, and manual milling machines. The coarse pitch tooth geometry reduces cutting forces and helps clear chips efficiently during heavy passes. It is a non-centercutting tool, meaning it is not designed for plunge cuts directly into solid material. Typical applications include slotting, peripheral milling, and step milling in shop and production environments where a TiAlN-coated cobalt tool offers an advantage over uncoated HSS in elevated-heat cuts.\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 applications\u003c\/li\u003e\n\u003cli\u003eCoarse pitch roughing geometry reduces cutting forces and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003e1\/2 inch shank diameter matches 1\/2 inch collets and end mill holders directly\u003c\/li\u003e\n\u003cli\u003eSingle-end design; non-centercutting — not suitable for direct plunge 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 end mill holders, collet chucks, and milling machine spindles accepting 1\/2 inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the milling machine spindle is fully stopped and the machine is in a safe, locked state before inserting or removing the tool. Use a properly sized collet or end mill holder torqued to the toolholder manufacturer's specification. Confirm runout with a dial indicator before beginning a roughing pass, as excessive runout accelerates tool wear and reduces cut quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5 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: TiAlN\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 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5 inches)\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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: 62852405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737232965938,"sku":"62852405","price":97.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52d6cb789c0fbe385b67bf7904e6f188_1c5f310c-cb53-4f29-9bd7-dfa71621bfc0.jpg?v=1788785865","url":"https:\/\/voomisupply.com\/products\/hertel-62852405-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
