It features a 3\/16 inch (0.1875 inch) mill diameter with a 0.01 inch corner radius, producing a controlled edge break or fillet on machined features. The 5\/8 inch length of cut and 2 inch overall length suit it for shallow-to-moderate depth slotting, profiling, and peripheral milling. With 2 flutes in a right-hand spiral configuration, it delivers efficient chip evacuation at higher feed rates. Micrograin solid carbide construction provides rigidity and wear resistance without a coating, making it suitable for dry or light-fluid cutting in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where a small corner radius is required to reduce stress concentrations at part shoulders or to meet drawing callouts for blended edges. Single-end, centercutting geometry allows plunge entry as well as conventional profiling passes. The 3\/16 inch shank diameter fits standard collets and toolholders in that bore size. It is appropriate for job shops, tool rooms, and production environments handling small-to-medium workpieces in steel, aluminum, brass, or similar machinable materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide body for improved wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003e0.01 inch corner radius for controlled edge blending and reduced stress risers on finished parts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled start hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flutes promote efficient chip flow and consistent surface finish\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish compatible with a wide range of cutting fluids and dry machining setups\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 3\/16 inch shank diameter for standard collet compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill for use in standard 3\/16 inch collets and toolholders on CNC machining centers or manual knee mills; no specific model compatibility was provided by the manufacturer for this part number.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with toolholder torque requirements and runout specifications for solid carbide end mills. Ensure the machine spindle is fully stopped and the control is in a safe state before loading or removing the tool. Confirm collet bore size matches the 3\/16 inch shank diameter and that the shank is seated to the minimum recommended engagement depth for the holder style in use. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material, as carbide end mills of this diameter are susceptible to breakage under excessive radial or axial load.\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\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\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\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\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: 12181291\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742671077682,"sku":"12181291","price":34.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e89442c7c0f5d634fc07392603a686d4.jpg?v=1788838729","url":"https:\/\/voomisupply.com\/products\/accupro-12181291-corner-radius-end-mill-3-16-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
