Built as a double-end tool with a 0.031-inch radius and a 1\/8-inch mill diameter, it delivers consistent edge geometry in both ferrous and non-ferrous materials. The uncoated bright finish makes it well suited for aluminum, brass, and other non-ferrous alloys where coating adhesion is not required. Two right-hand flutes provide efficient chip evacuation in small-diameter applications. Machinists and tool-and-die professionals rely on this style of end mill for edge-break and radius-blending operations on CNC mills and manual machines alike.\u003c\/p\u003e\u003cp\u003eThis end mill is used in precision machining environments where a controlled corner radius is required on part edges, slots, or pockets. It is appropriate for light-duty profiling and finishing passes in job shop, production, and toolroom settings. The 1\/8-inch shank diameter fits standard collet systems commonly found on CNC machining centers and manual knee mills. The double-end configuration extends tool life by providing two usable cutting ends before the tool is retired.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.031-inch corner radius for precise edge-rounding and radius-blending operations\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in small-diameter tooling\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends, extending usable tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC and manual mill setups\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish suited for non-ferrous and non-abrasive material applications\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits standard collet and tool holder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit corner rounding end mill for standard 1\/8-inch collet and tool holder systems used on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out state per applicable shop safety procedures. Seat the shank fully and evenly in the collet before tightening to the collet nut torque range specified by the collet manufacturer. Inspect the cutting edges and shank for runout after installation using a dial indicator before beginning a cut. Do not exceed the tool diameter-to-depth-of-cut ratios appropriate for solid carbide small-diameter end mills.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.063 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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\u003eSingle or Double End\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: 12180309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727125053746,"sku":"12180309","price":51.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b62dfa0c670f546aa1a37ed97aed87d6.jpg?v=1788673751","url":"https:\/\/voomisupply.com\/products\/accupro-12180309-corner-rounding-end-mill-1-8-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
