With a 3\/4 inch diameter and a 0.09 inch corner radius, it produces clean, radiused cuts that reduce stress concentrations at part corners. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Running 4 right-hand spiral flutes in a right-hand cutting direction, this extra-long series end mill offers a 3 inch length of cut and a 6 inch overall length, making it suitable for deep-pocket and extended-reach applications. Machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual mills working with ferrous and non-ferrous materials where a corner radius profile is required. The single-end, centercutting design allows plunge entry as well as lateral passes. The extra-long configuration accommodates workpieces or fixtures requiring clearance beyond what standard-length end mills can reach. The bright, uncoated finish makes it appropriate for applications where coating interaction with the workpiece material is a concern or where re-sharpening is planned.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.09 inch corner radius for stress-reducing radiused edges on machined parts\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation during deep cuts\u003c\/li\u003e\n  \u003cli\u003eExtra-long series with 3 inch LOC and 6 inch OAL for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with a wide range of materials and re-sharpening workflows\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool for CNC machining centers and manual mills accepting a 3\/4 inch straight shank end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. The machine spindle must be fully stopped and the tool changer or spindle lock engaged before inserting or removing the end mill from the collet or tool holder. Verify that shank diameter tolerance and runout are within acceptable limits before operation, as improper seating can cause tool deflection or breakage. Follow applicable shop safety procedures and machine manufacturer guidelines for tool clamping torque and maximum RPM ratings for this diameter and reach.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches (1.0000 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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\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\u003eWeight\u003c\/strong\u003e: 1 pound\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: 12183371\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748075077938,"sku":"12183371","price":432.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eba2fbd9c94b6bc8275f05a612d4301c.jpg?v=1788888771","url":"https:\/\/voomisupply.com\/products\/accupro-12183371-corner-radius-end-mill-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
