It carries a 1\/16-inch (0.0625-inch) corner radius and a 3\/16-inch (0.1875-inch) mill diameter, making it well suited for small-feature edge work where tight tolerances are required. The tool features an AlTiN (aluminum titanium nitride) coating that improves heat resistance and extends tool life in demanding cutting conditions. With two straight flutes and right-hand cutting and flute direction, it is a standard choice for machinists and toolroom professionals working on CNC mills and manual milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for edge-rounding and radius-milling operations across a broad spectrum of materials, including steel, stainless steel, cast iron, non-ferrous metals, and super alloys and titanium. The double-end configuration provides a second usable cutting end, extending service life per tool. It is appropriate for both production floor and job-shop environments where consistent corner geometry is required on precision components. The 2-inch overall length and 3\/16-inch cylindrical shank are suited to standard collet and end mill holders found on most vertical milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool for extended use\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and wear life on hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction supports edge sharpness and rigidity in demanding cuts\u003c\/li\u003e\n\u003cli\u003e1\/16-inch corner radius with 0.0400-inch tip diameter for small-feature profile accuracy\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting and flute direction compatible with standard milling machine spindle rotation\u003c\/li\u003e\n\u003cli\u003eRated for steel, stainless steel, cast iron, non-ferrous metals, and super alloys and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for use in milling operations requiring a 3\/16-inch diameter corner rounding end mill with a 1\/16-inch radius and 3\/16-inch cylindrical shank.

Ensure the machine spindle is fully stopped and the collet or end mill holder is clean and free of debris before seating the shank. Verify runout with a dial indicator after installation, as excessive runout accelerates edge wear on carbide tooling. Coolant-through is not supported on this tool; apply flood or mist coolant at the cutting zone as needed per shop practice.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/16 inches (0.0625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.0400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 0 degrees\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 Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Super Alloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INTERNAL TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 68-1600-C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67906832597298,"sku":"68-1600-C","price":73.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4dc0dd7b1757d8d6ad31ca416f35cda8.jpg?v=1791171885","url":"https:\/\/voomisupply.com\/products\/internal-tool-68-1600-c-corner-rounding-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
