Built with an AlTiN coating for improved heat resistance and tool life at elevated cutting speeds, this double-end mill measures 5\/16 inches in diameter with a matching 5\/16 inches shank diameter and a 7\/64 inches corner radius. The double-end configuration offers two usable ends, extending tool life between changes. With 2 flutes and a flared series geometry, it suits finish-pass edge-breaking and radius forming work in hard metals and alloys. CNC machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for edge rounding and radius profiling operations on milling machines and CNC machining centers in job shops, tool rooms, and production environments. It performs well in ferrous and hardened materials where the AlTiN coating provides thermal protection. The 7\/64 inches radius and 0.0580 inches tip diameter make it appropriate for tight-tolerance radius work where edge geometry consistency is critical. The flared corner rounding series is typically applied in finishing passes rather than heavy stock removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating enhances heat resistance and extends tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool, reducing per-edge cost\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability during precision radius cuts\u003c\/li\u003e\n\u003cli\u003e7\/64 inches corner radius with 0.0580 inches tip diameter for consistent edge geometry\u003c\/li\u003e\n\u003cli\u003e2-flute flared geometry optimized for finishing passes and edge-rounding applications\u003c\/li\u003e\n\u003cli\u003e5\/16 inches shank diameter matches mill diameter for straightforward tool holding compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank corner rounding end mill compatible with 5\/16 inches collets and tool holders on CNC milling machines and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Confirm the tool holder collet size matches the 5\/16 inches shank diameter before seating the tool. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify runout after installation and before beginning a cut to protect both the workpiece and the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 7\/64 inches (0.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.0580 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Corner Rounding End Mills - 2 and 4 Flute - Flared\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17109-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51739557921074,"sku":"17109-C3","price":187.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20d8d835dec10eb040b707d6164de3e8.jpg?v=1788816256","url":"https:\/\/voomisupply.com\/products\/harvey-tool-17109-c3-corner-rounding-end-mill-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
