Built from M42 cobalt high-speed steel, it delivers the heat and wear resistance needed for harder workpiece materials. The 1\/2 inch diameter cutter carries a TiCN coating that further extends tool life by reducing friction and surface adhesion. Four coarse-pitch flutes channel chips away efficiently, and the center-cutting geometry allows plunge entry as well as peripheral milling. This tool is installed and operated by machinists and tool-and-die professionals working with CNC mills, manual knee mills, and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is suited for ferrous and non-ferrous stock removal passes where a fine finish is secondary to cycle time and metal removal rate. The regular-length geometry keeps the 1\/2 inch shank compatible with standard ER and end mill collet chucks. A 2 inch length of cut provides sufficient depth engagement for most roughing passes in mold work, fixture fabrication, and general job shop production. Right-hand cut and right-hand flute direction are standard for conventional CNC spindle configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat resistance compared to standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in ferrous applications\u003c\/li\u003e\n  \u003cli\u003eCoarse pitch, 4-flute design maximizes chip clearance during heavy roughing cuts\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry supports plunge milling entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral match standard CNC and manual mill spindle direction\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch shank fits common collet chucks and end mill holders without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for 1\/2 inch end mill holders, ER32 collets, and equivalent toolholding systems used on standard vertical and horizontal milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank to the specified collet or holder torque using a calibrated torque wrench and follow the toolholder manufacturer's clamping procedure. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates premature tool wear on coated HSS end mills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 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)\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\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: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 41120627\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754453565746,"sku":"41120627","price":114.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8367bcc6e39d1f9063794d3542dac7e6.jpg?v=1788945526","url":"https:\/\/voomisupply.com\/products\/hertel-41120627-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
