Built from solid carbide, this tool delivers the rigidity and wear resistance required for production milling in ferrous and non-ferrous materials. The 0.062 inch corner radius, 1\/4 inch mill diameter, and 4-flute geometry make it well suited for finishing passes where edge profile consistency matters. The uncoated bright finish allows use across a broad range of materials without coating compatibility concerns. Machinists, toolroom operators, and CNC programmers working in job shops or manufacturing environments select this tool for edge-break and radius-profiling operations.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard 1\/4 inch toolholders and collets used on vertical machining centers, CNC knee mills, and manual milling machines. The double-end configuration provides two usable cutting ends, extending tool life between changes. The right-hand cut and right-hand flute direction are compatible with standard spindle rotation on conventional milling setups. It is appropriate for light to moderate material removal on parts requiring consistent corner radii on external edges.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in milling applications\u003c\/li\u003e\n\u003cli\u003e0.062 inch corner radius for precise convex edge profiling\u003c\/li\u003e\n\u003cli\u003e4-flute geometry supports smooth surface finish on finishing passes\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle compatibility\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4 inch collets and toolholders on CNC machining centers and conventional vertical mills with right-hand spindle rotation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention mechanism per the toolholder manufacturer guidelines. Verify runout with a dial indicator before production use to confirm proper seating and avoid premature tool wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.062 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.1210 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 Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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\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: 12180387\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728633430322,"sku":"12180387","price":109.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dda89d56b4d194bc1c357028059a979e.jpg?v=1788694222","url":"https:\/\/voomisupply.com\/products\/accupro-12180387-corner-rounding-end-mill-1-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
