Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting ferrous metals, stainless steels, and other tough alloys. The 1\/2 inch diameter cutter features 4 flutes with a right-hand cutting and right-hand flute direction, a 1.25 inch length of cut, and a 3.25 inch overall length. The bright, uncoated finish is suited for applications where coating adhesion is not required or where re-sharpening is anticipated. This tool is used by machinists and tool-and-die professionals in manual and CNC milling setups.\u003c\/p\u003e\u003cp\u003eThe 02499200 is intended for roughing passes where stock removal rate is the priority over surface finish. The center-cutting design allows plunge entry, adding flexibility in pocket milling and slotting operations. The regular length profile fits standard milling chucks and collet holders without requiring extended-reach setups. It is well suited to job shops, maintenance machining, and production environments where cobalt tooling is preferred over carbide due to shock resistance or cost considerations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e4-flute configuration optimized for roughing and rapid stock removal\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports plunge milling and pocket entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand helix geometry for conventional milling setups\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — resharpenable without coating concerns\u003c\/li\u003e\n\u003cli\u003eRegular length profile for compatibility with standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for 1\/2 inch collet holders, end mill adapters, and milling chucks used in vertical and horizontal milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended engagement depth in the toolholder to prevent pullout under roughing loads. Verify runout with an indicator before beginning cuts when tight tolerances are required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 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\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 02499200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749493014834,"sku":"02499200","price":44.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c704cca36b74e6e8cfd06d34b1556b3.jpg?v=1788906790","url":"https:\/\/voomisupply.com\/products\/hertel-02499200-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
