Built from solid carbide with a TiCN (titanium carbonitride) coating, it delivers hardness and heat resistance suited for cutting ferrous and non-ferrous metals, alloys, and similar materials. The tool features a 0.156-inch corner radius, a 3\/8-inch mill diameter, and a 0.063-inch tip diameter. Two right-hand flutes with a right-hand cutting direction provide efficient chip evacuation. Machinists and tool-and-die professionals install this end mill in standard CNC or manual milling setups where edge rounding and profile accuracy are required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for shop and production environments where repeatable corner radii are needed on metal components. The double-end configuration extends tool life by offering two usable cutting ends, reducing downtime during high-volume or repetitive edge-profiling work. The 3\/8-inch shank fits standard collets and tool holders of the same bore size, making it straightforward to integrate into existing setups without additional adapters in most cases.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in metal cutting applications\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool, extending usable tool life\u003c\/li\u003e\n  \u003cli\u003e0.156-inch corner radius with 0.063-inch tip diameter for precise edge profiling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard milling spindle compatibility\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry supports efficient chip clearance during edge-rounding passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use corner rounding end mill for standard 3\/8-inch collet and tool holder setups in CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Confirm the collet or tool holder bore matches the 3\/8-inch shank diameter before seating the tool. Follow applicable shop safety procedures and manufacturer feed and speed recommendations for the workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 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\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  \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: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12180358\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750564495666,"sku":"12180358","price":141.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c01c829c06d70147715b13c70b3ffd1.jpg?v=1788916749","url":"https:\/\/voomisupply.com\/products\/accupro-12180358-corner-rounding-end-mill-3-8-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
