Built from M42 cobalt high-speed steel with a bright, uncoated finish, it measures 5\/16 inch (0.3125 inch) in diameter with a 3\/4 inch length of cut and a 2-1\/2 inch overall length. The 3\/8 inch shank diameter seats securely in standard collets and tool holders. With 3 right-hand flutes and right-hand cutting direction, this end mill is suited for roughing passes where stock removal rate matters more than surface finish. It is not center-cutting and is not designed for plunge entry.\u003c\/p\u003e\u003cp\u003eThis end mill is used in manual and CNC milling applications on ferrous and non-ferrous metals where heat resistance and edge retention are priorities. M42 cobalt composition provides added hardness over standard M2 high-speed steel, making it a practical choice for tougher alloys, stainless steel, and harder workpiece materials. Machinists and tool-and-die professionals use this style of end mill for roughing slots, pockets, and profiles before finishing passes with a standard end mill.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for improved heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e5\/16 inch cutting diameter with 3\/4 inch length of cut\u003c\/li\u003e\n\u003cli\u003e3 right-hand flutes with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank diameter for standard collet compatibility\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose roughing\u003c\/li\u003e\n\u003cli\u003eSingle-end design — one active cutting end per tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for use in milling machines accepting a 3\/8 inch shank, including bridgeport-style knee mills and CNC machining centers with compatible collet or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using a collet chuck or end mill holder rated for the 3\/8 inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. This tool is not center-cutting — avoid programming direct plunge moves into the workpiece. Confirm runout with a dial indicator after seating the tool to avoid premature edge wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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: 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: 0.07 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 724-2050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723012636978,"sku":"724-2050","price":54.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dac04ec702f040d4aaec6f8da5341b1c.jpg?v=1788599255","url":"https:\/\/voomisupply.com\/products\/value-collection-724-2050-roughing-end-mill-5-16-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
