With a 1\/8-inch corner radius and a 0.3125-inch mill diameter, it produces consistent, smooth transitions in a single pass. The TiN (titanium nitride) coating increases surface hardness and reduces friction, extending tool life across a wide range of ferrous and non-ferrous materials. The double-end configuration delivers two usable cutting ends per tool, improving cost efficiency in production environments. Right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use on CNC machining centers and manual knee mills in job shops, production facilities, and toolroom environments. It is commonly applied to mold and die work, fixture components, and general precision machined parts where sharp corners must be blended to a specific radius. The 5\/16-inch shank diameter fits standard ER collet chucks and end mill holders found on most vertical machining centers. The two-flute geometry is well-suited for lighter finishing cuts and improved chip evacuation in tighter pockets.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and heat resistance compared to HSS tooling\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces tool wear and improves surface finish quality\u003c\/li\u003e\n\u003cli\u003eDouble-end design offers two cutting ends per tool for extended usable life\u003c\/li\u003e\n\u003cli\u003e1\/8-inch corner radius machines consistent edge profiles in a single operation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and flute direction compatible with standard CNC milling spindles\u003c\/li\u003e\n\u003cli\u003e0.0630-inch tip diameter allows profiling close to floor surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or upgrade for corner rounding end mills with a 5\/16-inch shank diameter and 1\/8-inch radius in standard ER collet chucks and end mill holders on vertical CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention nut to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning the cut cycle, as excessive runout will accelerate wear on a 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\u003eCorner Radius\u003c\/strong\u003e: 1\/8 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\u003eTip Diameter\u003c\/strong\u003e: 0.0630 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: TiN (Titanium Nitride)\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12179329\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732563427634,"sku":"12179329","price":97.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7cea6c1a95e133ab1eab77f7c16116e.jpg?v=1788744484","url":"https:\/\/voomisupply.com\/products\/accupro-12179329-corner-rounding-end-mill-1-8-in-radius","provider":"Voomi Supply","version":"1.0","type":"link"}
