With a 0.031-inch corner radius and a 3\/16-inch (0.1875-inch) mill diameter, this tool produces consistent, repeatable radius profiles in a single pass. The four-flute, right-hand cutting geometry promotes chip evacuation and surface finish quality. At 2 inches overall length with a matching 3\/16-inch shank diameter, it fits standard collet toolholding setups on CNC mills and manual knee mills. The bright, uncoated carbide construction suits general-purpose ferrous and non-ferrous applications where coating is not required.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for production and job-shop environments where radiusing external corners, blending edges, or removing sharp burrs is a routine operation. The double-end configuration doubles tool life before discard, making it practical for high-cycle toolpaths. Typical applications include mold and die work, fixture fabrication, and precision part finishing in aerospace, automotive, and general machining contexts. A 0.120-inch tip diameter accommodates moderate material removal at the corner profile without sacrificing rigidity in the shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.031-inch corner radius for fine, repeatable edge profiling\u003c\/li\u003e\n\u003cli\u003eDouble-end design extends usable tool life\u003c\/li\u003e\n\u003cli\u003eFour right-hand flutes with right-hand cutting direction for smooth chip flow\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e3\/16-inch shank fits standard ER and straight-bore collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank corner rounding end mill compatible with CNC machining centers and manual mills equipped with 3\/16-inch collet or toolholding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine in an e-stop or lock-out state. Seat the shank fully into the collet or toolholder before tightening to manufacturer-specified clamping torque for the holder type in use. Inspect the cutting edges and corner radius for chips or wear before each use. Follow shop runout tolerances and balance requirements as applicable to the machine and spindle speed range.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.120 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: 12180372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732492878130,"sku":"12180372","price":98.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c0ea45c5d4c3961ef7caaba2a3dc016.jpg?v=1788743542","url":"https:\/\/voomisupply.com\/products\/accupro-12180372-corner-rounding-end-mill-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
