It features a 5\/8 inch diameter with a 0.0900 inch corner radius and a 1-1\/4 inch length of cut, making it well suited for finishing passes and contouring work where corner breakout and edge chipping must be controlled. The 4-flute, right-hand spiral configuration supports efficient chip evacuation and smooth surface finishes. A 40-degree helix angle improves cutting action on harder materials. This tool is installed and operated by machinists and CNC programmers working with machining centers, knee mills, and similar equipment.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in job shops, tool rooms, and production machining environments. It handles a range of ferrous and non-ferrous materials where a corner radius profile is required to reduce stress concentrations in milled pockets and slots. The single-end, centercutting design allows plunge milling in addition to peripheral and slot cutting. The bright\/uncoated finish makes it appropriate for general-purpose applications and materials where coated tooling is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0900 inch corner radius reduces stress risers in milled features and extends part life\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral construction with 40-degree helix for efficient chip removal and smooth finishes\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for general-purpose and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 5\/8 inch shank diameter for standard collet and end mill holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 5\/8 inch shank end mill holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists using a properly sized collet, end mill holder, or hydraulic chuck rated for the 5\/8 inch shank diameter. Ensure the spindle and toolholder are clean and free of debris before seating the tool to maintain runout tolerances within the shank diameter tolerance of -0.0001 to -0.0004 inches. Follow machine manufacturer feed, speed, and depth-of-cut recommendations for solid carbide tooling. Inspect the cutting edges before each use and replace the tool if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -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\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0900 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\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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: 0.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 12182627\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738721878322,"sku":"12182627","price":126.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69f565da3747fd45629e00853b74c070.jpg?v=1788803415","url":"https:\/\/voomisupply.com\/products\/accupro-12182627-corner-radius-end-mill-5-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
