Built from solid carbide with a TiCN (titanium carbonitride) coating, it provides high wear resistance and extended tool life in demanding machining environments. The cutter features a 0.02 inch corner radius, a 3\/16 inch mill diameter, and four right-hand flutes for efficient chip evacuation. With an overall length of 2 inches and a matching 3\/16 inch shank diameter, it fits standard collet toolholding systems. Machinists and CNC operators in job shops and precision manufacturing facilities are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for corner rounding and edge contouring on ferrous and non-ferrous metals. The double-end configuration delivers two usable cutting ends per tool, reducing per-edge tooling cost in production environments. The 0.02 inch radius produces a small, controlled radius break on edges and shoulders, making it appropriate for finishing passes on tight-tolerance components. Right-hand cutting and flute direction are standard for conventional CNC milling setups.\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\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 edges per tool\u003c\/li\u003e\n  \u003cli\u003e0.02 inch corner radius for precise, small-radius edge contouring\u003c\/li\u003e\n  \u003cli\u003e4 right-hand flutes with right-hand cutting direction for standard CNC milling\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch shank diameter fits standard collet and toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with collet toolholding systems that accept a 3\/16 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank fully into the collet or toolholder and torque to the toolholder manufacturer's specification before running. Confirm spindle direction is set to right-hand rotation before engaging the cut. Inspect the cutting edges for chips or wear before each use, particularly on the double-end style where the second end may have been previously used.\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 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.02 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: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.142 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\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\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\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: 12180367\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754595549490,"sku":"12180367","price":141.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64e75dec806b62da9e9bae63593cc12c.jpg?v=1788946957","url":"https:\/\/voomisupply.com\/products\/accupro-12180367-corner-rounding-end-mill-3-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
