Built from solid carbide and coated with TiCN (Titanium Carbonitride), it delivers extended tool life and improved wear resistance in demanding cutting applications. The mill features a 0.04-inch corner radius and a 0.125-inch (1\/8 inch) diameter, making it well suited for tight-tolerance work where consistent, repeatable edge geometry is required. With 2 right-hand flutes and right-hand cutting direction, it is a standard choice for machinists working on CNC machining centers and manual mills alike.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in metalworking shops for rounding sharp corners and producing uniform radius profiles on ferrous and non-ferrous materials. The double-end configuration provides two usable cutting ends, extending overall tool value per unit. It is appropriate for light to moderate material removal passes where edge finishing and dimensional consistency are the priority. The 1\/8-inch shank diameter fits standard collet systems commonly found on CNC mills, tool-and-die setups, and precision machining operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life compared to uncoated carbide\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003e0.04-inch corner radius for consistent, tight-tolerance edge rounding\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute geometry for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003e0.045-inch tip diameter suited for fine-detail corner profiling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 1\/8-inch shank collet systems used in CNC machining centers and manual milling setups requiring a 0.04-inch corner radius end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard tooling procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the end mill from the collet. Verify collet size matches the 1\/8-inch shank diameter and that the tool is seated and torqued to the collet manufacturer specification. Inspect the cutting edges for chips or wear before each use, particularly on the double-end tool where the second end may have been previously run.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.04 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.045 inches\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\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: TiCN\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: 0.01 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: 12180316\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738647265586,"sku":"12180316","price":56.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4738ad07a1914ce1e0ab7548279272f0.jpg?v=1788802301","url":"https:\/\/voomisupply.com\/products\/accupro-12180316-corner-rounding-end-mill-1-8-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
