It carries a 3\/16-inch cutting diameter with a 0.03-inch corner radius and a 5\/8-inch length of cut, making it well suited for producing consistent, radiused inside corners and contoured profiles. The bright, uncoated finish preserves the as-ground edge geometry and is appropriate for applications where a coating would add undesirable edge buildup. Machinists and toolroom professionals install and run this end mill on CNC machining centers and manual mills requiring tight dimensional control.\u003c\/p\u003e\u003cp\u003eThis end mill is used in toolroom, die-and-mold, and production milling environments where a small-diameter corner radius tool is required to blend transitions, finish pocket floors, or machine radiused slots. Its centercutting design allows plunge entry, expanding the range of operations it can perform without a pre-drilled pilot. The 2-flute configuration provides adequate chip clearance for both ferrous and non-ferrous workpieces at moderate feed rates. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03-inch corner radius produces consistent radiused transitions on inside corners and pocket floors\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction delivers high rigidity and wear resistance compared to high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge entry without a separate pilot hole\u003c\/li\u003e\n\u003cli\u003e2-flute spiral geometry promotes chip evacuation in both ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains precise as-ground edge geometry for close-tolerance work\u003c\/li\u003e\n\u003cli\u003eMatched shank and cutting diameter at 3\/16 inch simplifies collet and toolholder selection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank corner radius end mill compatible with 3\/16-inch collets, ER collet chucks, and end mill holders used on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before seating or removing the tool. Insert the shank fully into the collet or holder to maximize rigidity and minimize runout; shank diameter tolerance is specified to -0.0001 to -0.0004 inches for precise holder fit. Inspect the collet and holder bore for chips or wear before clamping, as debris will increase runout and shorten tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 12181294\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744020693298,"sku":"12181294","price":33.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10ec92082ef698a93bbbf6550158356e.jpg?v=1788853040","url":"https:\/\/voomisupply.com\/products\/accupro-12181294-corner-radius-end-mill-3-16-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
