Built from solid carbide and coated with titanium carbonitride (TiCN), it delivers a 1\/16-inch radius profile with a 3\/16-inch mill diameter. The two-flute, right-hand cutting geometry provides clean material removal on ferrous and non-ferrous metals. At 2 inches overall length and 0.03 pounds, it fits standard toolholders used in CNC machining centers and manual mills. Machinists and tool-and-die professionals rely on this type of end mill to break sharp edges, add uniform radii, and meet tight finishing tolerances on production and prototype parts.\u003c\/p\u003e\n\u003cp\u003eThis corner rounding end mill is suited for light to medium-duty milling operations where a consistent edge radius is required. The double-end configuration extends tool life by offering two usable cutting ends. The TiCN coating reduces friction and improves wear resistance compared to uncoated carbide, making it a practical choice for high-cycle runs on steel, stainless, aluminum, and similar materials. The 3\/16-inch shank diameter fits collets and toolholders commonly found in both CNC and manual milling setups across job shops and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/16-inch corner radius for precise, repeatable edge profiling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces wear and lowers cutting friction\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 milling setups\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.03 pounds with a compact 2-inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement-style corner rounding end mill for 3\/16-inch collets and toolholders in CNC machining centers and manual milling machines requiring a 1\/16-inch radius profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the 3\/16-inch shank fully in the collet or toolholder and torque the drawbar or nut per the machine manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates carbide wear and reduces finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/16 inches (0.0620 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\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\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 (Titanium Carbonitride)\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: 0.03 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: 12180328\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730048909618,"sku":"12180328","price":74.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd79147033ae7a3c79c060ba38a81d39.jpg?v=1788710783","url":"https:\/\/voomisupply.com\/products\/accupro-12180328-corner-rounding-end-mill-3-16-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
