Built from M42 cobalt high-speed steel, this single-end tool offers improved heat and wear resistance compared to standard HSS end mills, making it well suited for harder ferrous materials and higher-feed operations. The mill measures 7\/8 inch in diameter with a 7\/32 inch radius and a 1\/2 inch shank diameter. It features 4 flutes with a right-hand cutting and right-hand flute direction, and carries a bright uncoated finish that is ready for use straight from the package.\u003c\/p\u003e\n\u003cp\u003eThis corner rounding end mill is used in manual knee mills, CNC machining centers, and toolroom applications where a controlled edge radius is required. Typical applications include breaking sharp corners on steel, stainless, and alloy workpieces to improve part aesthetics, reduce stress concentration, and prepare surfaces for coating or assembly. It is primarily installed by machinists and tool-and-die professionals working in job shops, aerospace, and general manufacturing environments. The 1\/2 inch shank fits standard R8, CAT, and BT toolholders commonly found in vertical machining centers and knee mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved heat resistance and tool life in harder materials\u003c\/li\u003e\n  \u003cli\u003e7\/32 inch corner radius produces a consistent, repeatable edge profile\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry balances chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral for conventional milling setups\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose ferrous machining\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with 1\/2 inch shank for compatibility with standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use corner rounding end mill for vertical machining centers and manual mills accepting a 1\/2 inch shank diameter toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist. Ensure the machine spindle is fully stopped and the toolholder is clean and free of chips before seating the shank. Verify runout with a dial indicator after tightening to minimize premature edge wear. Follow the machine manufacturer guidelines for speed and feed rates appropriate to M42 cobalt end mills and the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.875 inches (7\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.21875 inches (7\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 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\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: 723-6456\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723405164850,"sku":"723-6456","price":98.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66669ff81b5b32bf8c1dc985434ac7eb.jpg?v=1788604503","url":"https:\/\/voomisupply.com\/products\/value-collection-723-6456-corner-rounding-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
