Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting tough ferrous and non-ferrous materials. The 5\/16 inch (0.3125 inch) cutting diameter pairs with a 1-3\/8 inch (1.3750 inch) length of cut and a 3\/8 inch shank, making it suited for moderate-depth roughing passes. The bright, uncoated finish keeps the surface free of added coating variables, which some machinists prefer for cobalt tooling. This end mill is centercutting, allowing plunge entry into workpieces without a pre-drilled pilot hole.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills. It is appropriate for roughing operations in steel, stainless steel, cast iron, and similar hard materials where high heat generation demands cobalt-grade tooling over standard HSS. The single-end configuration and right-hand cutting and flute direction make it a standard fit for conventional milling setups. Machinists, tool-and-die workers, and maintenance technicians performing metal removal in job shop or production environments are the typical users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt material grade for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003e4-flute configuration balances chip clearance with surface contact for roughing passes\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of cutting fluids and lubricants\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for use in standard milling machine spindles\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank diameter fits common collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank roughing end mill for use in milling machines and machining centers that accept a 3\/8 inch shank.

Secure the 3\/8 inch shank in a properly sized collet or end mill holder torqued to the machine manufacturer's specification using the appropriate spanner or wrench. Inspect the cutting edges for chips or damage before each use. Follow applicable shop safety practices and machine-specific operating procedures when setting speeds and feeds for cobalt tooling.\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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\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: 1-3\/8 inches (1.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Fractional)\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal)\u003c\/strong\u003e: 0.3750 inches\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 724-0059\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696342860082,"sku":"724-0059","price":81.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae419bff0aaffb1b0f281e9639300fb4.jpg?v=1788341680","url":"https:\/\/voomisupply.com\/products\/value-collection-724-0059-roughing-end-mill-5-16-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
