Built from M42 cobalt high-speed steel, it offers increased heat and wear resistance compared to standard M2 HSS tooling, making it well suited for harder ferrous materials and interrupted cuts. The cutter measures 7\/16 inches in diameter with a 3\/64 inches corner radius and features four right-hand flutes with a right-hand cutting direction. The bright, uncoated finish is the as-ground surface with no additional coating applied. It is typically installed by machinists and tool-and-die technicians in vertical milling machines, CNC knee mills, and manual bridgeport-style setups.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in metalworking shops for edge-breaking and corner rounding operations on steel, stainless steel, cast iron, and similar materials. The 3\/8 inches shank diameter fits standard collets and end mill holders common in both manual and CNC milling equipment. The four-flute geometry provides a good balance of chip clearance and surface finish quality, making it appropriate for finishing passes on profiled edges in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved hardness and heat resistance over standard HSS grades\u003c\/li\u003e\n  \u003cli\u003e3\/64 inches corner radius produces a precise, repeatable edge profile\u003c\/li\u003e\n  \u003cli\u003eFour right-hand flutes with right-hand cutting direction for conventional milling setups\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating to delaminate or add dimensional variation to the radius\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with a 3\/8 inches straight shank for broad collet compatibility\u003c\/li\u003e\n  \u003cli\u003e0.4375 inches (7\/16 inches) cutter diameter suitable for moderate material removal on edge profiles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard end mill holders and collet chucks accepting a 3\/8 inches shank diameter, compatible with vertical milling machines, CNC machining centers, and manual knee mills equipped with R8, CAT, BT, or similar tooling systems using the appropriate 3\/8 inches collet or end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolroom practices. Ensure the spindle is fully powered down and locked before inserting or removing the end mill from the holder. Seat the shank to the full recommended engagement depth in the collet or end mill holder and verify tool runout before cutting. Consult machine manufacturer specifications for appropriate spindle speed and feed rate based on workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inches (0.04 mm)\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\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\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\u003eEnd Configuration\u003c\/strong\u003e: Single End\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: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 723-6408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711105827122,"sku":"723-6408","price":94.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8495cc4dcf94cd954273817e945459a7.jpg?v=1788474412","url":"https:\/\/voomisupply.com\/products\/value-collection-723-6408-corner-rounding-end-mill-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
