With a 0.05 inch radius and a 0.25 inch mill diameter, it generates a precise convex edge break in a single pass. The 4-flute geometry supports efficient chip evacuation and surface finish quality on ferrous and non-ferrous materials. The bright, uncoated finish makes it suitable for applications where coating interaction with the workpiece material is a concern. Machinists and tool-and-die professionals use this end mill on CNC machining centers and manual mills where edge-rounding operations are required.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for edge profiling operations on a range of materials in job shop, production, and tooling environments. The double-end configuration provides two usable cutting ends, extending tool life between changes. The 1\/4 inch shank diameter fits standard collets and end mill holders common to vertical machining centers and CNC routers. It is appropriate for light-to-moderate finishing passes where a controlled 0.05 inch radius is specified by drawing or inspection requirement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.05 inch corner radius delivers a precise, repeatable edge profile\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e4-flute configuration supports smooth surface finish and chip clearance\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction offers rigidity and wear resistance over high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for dry cutting or use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4 inch collets and end mill holders on CNC machining centers, vertical mills, and CNC routers requiring a 0.05 inch corner rounding profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's runout and tool-holding specifications. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Verify collet size matches the 1\/4 inch shank diameter before tightening. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.05 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.145 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 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 Type\u003c\/strong\u003e: Double End\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12180384\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730531909938,"sku":"12180384","price":120.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e986db763aeabecc720da58c8f63c8.jpg?v=1788719106","url":"https:\/\/voomisupply.com\/products\/accupro-12180384-corner-rounding-end-mill-1-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
