It features a 3\/16 inch (0.1875 inch) mill diameter with a 0.01 inch corner radius and a 3\/8 inch length of cut, making it well-suited for profiling, slotting, and contouring where a controlled edge radius is required. The single-end, centercutting design allows plunge entry as well as lateral passes. An AlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials. This tool is intended for use by machinists and toolroom technicians running CNC machining centers or manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is applied in precision machining environments where a small corner radius is needed to reduce stress concentrations at part features. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces in ferrous alloys, stainless steels, and high-temperature alloys. With a 2 inch overall length and a 3\/16 inch shank diameter matching the cutting diameter, it fits standard collet toolholding systems used in both production and prototype machining. It is a single-quantity tool suited for job shops, tool rooms, and production floor use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/16 inch (0.1875 inch) mill diameter with matched 3\/16 inch shank for direct collet mounting\u003c\/li\u003e\n  \u003cli\u003e0.01 inch corner radius reduces stress risers at workpiece features\u003c\/li\u003e\n  \u003cli\u003e3 right-hand spiral flutes with 40-degree helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating enhances heat resistance and wear life in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits plunge milling without a pre-drilled entry\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge retention at the small diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide end mill compatible with standard 3\/16 inch collet toolholding systems on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists using a collet or end mill holder matched to the 3\/16 inch shank diameter. Verify shank seating depth and collet runout before cutting to stay within the stated shank diameter tolerance. Ensure the spindle and machine are at a full stop before inserting or removing the tool. Follow shop-standard speeds and feeds for the coating and workpiece material; AlTiN-coated carbide tools are typically run dry or with air blast rather than flood coolant in high-temperature alloy applications.\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 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0002 to -0.0008 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.0015 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.375 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\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 (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: 12179348\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743283347762,"sku":"12179348","price":57.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0dd0a9fdab7b17cb4c0046d3e650ec8.jpg?v=1788845047","url":"https:\/\/voomisupply.com\/products\/accupro-12179348-corner-radius-end-mill-3-16-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
