It features a 5\/16 inch diameter with a 0.06 inch corner radius and a 4-flute, right-hand spiral configuration at a 40-degree helix angle. The micrograin carbide substrate provides wear resistance and edge retention at higher feed rates. At 2.5 inches overall length with a 3\/4 inch length of cut, this is a single-end, centercutting tool suited for slotting, profiling, and contour milling where a radius corner is required to reduce stress concentration at part shoulders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for finish profiling, pocket milling, and shoulder work where a defined corner radius is specified. The bright uncoated finish makes it suitable for aluminum, brass, and other non-ferrous materials, as well as general-purpose steel applications where a coated tool is not required. Machinists, tool-and-die makers, and CNC operators in job shops and production environments are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for extended tool life and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e0.06 inch corner radius reduces stress risers on machined part shoulders\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and right-hand cutting for standard CNC spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish with tolerance of +0.000000 to -0.002500 inches on mill diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-end corner radius end mill with a 5\/16 inch shank diameter, compatible with 5\/16 inch collets and end mill holders used in CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully in the collet or tool holder and torque to the holder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates edge wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 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\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eEnd Configuration\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 0.12 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: 12182494\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735055171890,"sku":"12182494","price":44.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4320b1d4ec906145a5ef85410632241.jpg?v=1788769728","url":"https:\/\/voomisupply.com\/products\/accupro-12182494-corner-radius-end-mill-5-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
