Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers solid wear resistance and heat tolerance in ferrous and non-ferrous machining. The cutter measures 3\/8 inch in diameter with a 1-1\/8 inch length of cut and a 2-15\/16 inch overall length. Four right-hand flutes with a roughing profile break chips aggressively, reducing cutting forces and vibration during heavy stock removal passes. Center-cutting geometry allows plunge entry. This tool is installed by machinists, toolmakers, and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for horizontal, vertical, and CNC milling machines in both manual and automated setups. It handles roughing passes on steels, alloy steels, and other materials where controlled chip load and thermal resistance are priorities. The 3\/8 inch shank diameter matches standard ER collets, end mill holders, and milling chucks without adapters. Single-end configuration means one cutting end with a straight shank on the opposite side.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat and wear resistance versus standard M2 tooling\u003c\/li\u003e\n\u003cli\u003eRoughing flute profile reduces cutting forces and controls chip formation during heavy passes\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design permits direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with conventional milling machine spindles\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with or without coolant\u003c\/li\u003e\n\u003cli\u003eEqual shank and cutter diameter at 3\/8 inch simplifies toolholder selection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing end mill for standard milling applications requiring a 3\/8 inch single-end cobalt cutter with a 3\/8 inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall by a qualified machinist using a properly torqued collet chuck or end mill holder rated for the spindle speed and material being cut. Ensure the milling machine spindle is fully stopped and the machine is locked out before changing tooling. Verify runout with a dial indicator after seating to confirm proper holder engagement. Follow shop-specific feeds, speeds, and depth-of-cut parameters for the workpiece material and machine capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 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: 1-1\/8 inches (1.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 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\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\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\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: 724-0086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693474316594,"sku":"724-0086","price":73.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e40303e61b5e45c73a6bf4e59681ec10.jpg?v=1788312932","url":"https:\/\/voomisupply.com\/products\/value-collection-724-0086-roughing-end-mill-3-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
