Built from M42 cobalt high-speed steel with a TiN coating, it handles harder workpiece materials where standard HSS tooling falls short. The cutter measures 3\/8 inch in diameter with a 7\/16 inch length of cut and a 2-3\/16 inch overall length. Four right-hand flutes and a right-hand cutting direction deliver efficient chip evacuation during roughing passes. This tool is suited for machinists and tool-and-die professionals running manual mills or CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for roughing operations on ferrous and non-ferrous metals in job shop, production machining, and maintenance environments. The cobalt M42 substrate offers improved heat and wear resistance compared to standard M2 HSS, making it a practical choice for cutting alloy steels, stainless, and other harder materials at moderate cutting speeds. It is a non-centercutting design, so plunge cutting is not recommended.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved hardness and heat resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e4 right-hand flutes with right-hand cutting direction for efficient chip removal\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank diameter matches standard collet and end mill holder tooling\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 7\/16 inch length of cut for roughing passes\u003c\/li\u003e\n\u003cli\u003eNon-centercutting geometry — not intended for plunge milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard 3\/8 inch single-end roughing end mills used in manual vertical mills and CNC machining centers equipped with 3\/8 inch collets or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard toolroom practices. Secure the shank fully into the collet or end mill holder to the recommended engagement depth before tightening. Verify spindle and workholding are fully stopped and locked out before changing tooling. Do not use this tool for plunge cuts, as it is a non-centercutting design.\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 inch)\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\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\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 inch)\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 723-6720\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696716153138,"sku":"723-6720","price":30.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc55e614b77decd8415cecc0862afbbf.jpg?v=1788345541","url":"https:\/\/voomisupply.com\/products\/value-collection-723-6720-roughing-end-mill-3-8-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
