With a 0.109 inch radius, a 5\/16 inch mill diameter, and a double-end configuration, this tool delivers two usable ends per unit — extending tool life and reducing changeover frequency on the shop floor. The uncoated bright finish is suited to ferrous and non-ferrous materials where coating compatibility or cost constraints are a factor. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills to produce consistent, smooth corner profiles without secondary deburring operations.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for edge-profiling operations in general machining, mold and die work, and precision part manufacturing where controlled corner radii are required by print. The right-hand cutting and right-hand flute direction make it compatible with standard spindle rotation on vertical machining centers. With a 0.094 inch tip diameter and two flutes, it is suited for light to moderate material removal on finished or near-finished surfaces. Typical users include CNC machinists, tool makers, and job shop operators working in production or prototype environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool, extending usable tool life\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction offers high rigidity and wear resistance compared to HSS tooling\u003c\/li\u003e\n\u003cli\u003e0.109 inch radius produces a consistent convex edge profile to print tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e5\/16 inch shank diameter fits standard collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for CNC vertical machining centers and manual mills using 5\/16 inch collets or end mill holders requiring a corner rounding profile end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before inserting or removing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth per the toolholder manufacturer guidelines. Verify runout with a dial indicator before cutting to avoid premature edge wear or chipping on a solid carbide 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\u003eRadius\u003c\/strong\u003e: 0.109 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.094 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 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 Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\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: Double End\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12180345\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738654605618,"sku":"12180345","price":79.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63f64951fadcf2c8ff72ece154d876f6.jpg?v=1788802388","url":"https:\/\/voomisupply.com\/products\/accupro-12180345-corner-rounding-end-mill-5-16-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
