Built from M42 cobalt high-speed steel, it delivers heat and wear resistance needed when cutting tough ferrous and non-ferrous materials at higher feed rates. The 3\/8-inch diameter cutter features 4 flutes with a bright, uncoated finish and a 7\/16-inch length of cut. Right-hand cutting and right-hand flute direction are standard for conventional milling setups. Centercutting capability allows plunge entry into workpiece material without a pre-drilled pilot hole.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for use in manual knee mills, CNC machining centers, and benchtop milling machines in job shop, maintenance, and light production environments. The 3\/8-inch shank fits standard ER collets, end mill holders, and Weldon-style set-screw holders common in most shop setups. It is appropriate for roughing passes on steel, stainless, cast iron, and similar materials where chip-clearing and feed rate take priority over surface finish.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat resistance compared to standard M2 HSS\u003c\/li\u003e\n\u003cli\u003e4-flute single-end geometry optimized for roughing passes and high material removal rates\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled starting hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for conventional use in standard spindle setups\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with or without cutting fluid\u003c\/li\u003e\n\u003cli\u003eMatching 3\/8-inch mill and shank diameter for straightforward toolholder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard roughing end mill with a 3\/8-inch straight shank compatible with ER collet chucks, Weldon flat-shank holders, and similar toolholding systems accepting 3\/8-inch shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and toolroom technicians. Ensure the machine spindle is fully stopped and locked before seating or removing the end mill from its holder. Verify collet or holder runout is within acceptable tolerance before beginning a cut, as excessive runout accelerates tool wear and degrades cut quality. Apply appropriate cutting fluid for the workpiece material to extend tool life.\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/16 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\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\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\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: 724-0071\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701550383410,"sku":"724-0071","price":28.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71c3d9097b798a44b3da6d29f55dae4d.jpg?v=1788401246","url":"https:\/\/voomisupply.com\/products\/value-collection-724-0071-roughing-end-mill-3-8-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
