Built from M42 cobalt high-speed steel with a bright, uncoated finish, it measures 0.625 inches in diameter with a 1.25-inch length of cut and a 3.375-inch overall length. The four-flute, right-hand cutting geometry with right-hand flute direction provides efficient chip evacuation during roughing passes. This tool is suited for machinists, tool-and-die workers, and production floor operators running manual mills or CNC machining centers where high-heat resistance and edge retention are required.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is appropriate for use on ferrous and non-ferrous metals where rapid stock removal is the priority before a finishing pass. The 5\/8-inch shank diameter matches the mill diameter, allowing direct clamping in standard collets or end mill holders without a reducer. It is not center-cutting, so it is not suitable for plunge entry. Typical applications include slot milling, shoulder milling, and profile roughing on steel, stainless steel, and similar alloys where cobalt tooling outperforms standard HSS under elevated cutting temperatures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand cut geometry for effective chip removal during roughing passes\u003c\/li\u003e\n  \u003cli\u003e0.625-inch mill diameter with matching 0.625-inch shank for direct-fit clamping\u003c\/li\u003e\n  \u003cli\u003e1.25-inch length of cut suitable for moderate-depth roughing applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — compatible with cutting fluids and coolant systems\u003c\/li\u003e\n  \u003cli\u003eNot center-cutting — requires a pre-drilled or pre-milled entry point\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard replacement roughing end mill for use in any manual or CNC milling machine accepting a 5\/8-inch shank end mill holder or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with toolholder torque procedures and runout inspection. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware per the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning the cut, and verify that entry strategy does not require plunge cutting, as this tool is not center-cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 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\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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: No\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: 724-2143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711654134066,"sku":"724-2143","price":79.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccb0253ed014c062f8496cc447437c4f.jpg?v=1788478201","url":"https:\/\/voomisupply.com\/products\/value-collection-724-2143-roughing-end-mill-5-8-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
