Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers heat resistance and edge retention in demanding cuts. The tool features a 1\/2 inch cutting diameter, a 3 inch length of cut, and a 5 inch overall length. Four flutes with a right-hand cutting and right-hand flute direction make it suitable for conventional roughing passes on ferrous and non-ferrous materials. Center-cutting geometry allows plunge entry. This end mill is installed and operated by machinists and tool-and-die professionals on vertical mills and CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for roughing applications where stock removal rate takes priority over surface finish. The cobalt M42 substrate handles elevated temperatures generated in harder steels, stainless, and high-nickel alloys better than standard M2 HSS tooling. A 1\/2 inch shank diameter matches standard R8, ER, and side-lock toolholders common in manual and CNC knee mills. It is a single-end tool, so the full length of cut is available from one working end. Typical applications include roughing pockets, slots, and profiles in job-shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry optimized for roughing and high material removal rates\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design permits direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand helix for standard spindle-direction compatibility\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with or without cutting fluid\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch shank diameter fits widely available collet and toolholder systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing end mill for standard 1\/2 inch toolholders on vertical milling machines and CNC machining centers requiring a single-end, 4-flute cobalt rougher.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists and CNC operators. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention nut to the toolholder specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on cobalt tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\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 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\u003eCentercutting\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\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 724-0128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690324820274,"sku":"724-0128","price":108.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9ed55a41ee78fb5ce6f4c7ad82abf6d.jpg?v=1788268804","url":"https:\/\/voomisupply.com\/products\/value-collection-724-0128-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
