With a 1\/2 inch mill diameter and a 0.01 inch corner radius, this tool produces controlled edge breaks and contoured profiles while reducing stress concentrations at part corners. The 4-flute, right-hand spiral configuration supports efficient chip evacuation and smooth surface finishes. At 4 inches overall length with a 1 inch length of cut, it suits a range of profiling, slotting, and peripheral milling tasks. Machinists and CNC operators in job shops and production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use on CNC machining centers and manual mills handling ferrous and non-ferrous materials where a tight corner radius is required. The bright\/uncoated finish makes it a practical choice for aluminum, brass, and similar materials where coating adhesion or heat buildup is not a primary concern. The centercutting design allows plunge entry, adding versatility for pocketing and ramp entry toolpaths. The long-length classification provides additional reach for deeper features without requiring extension holders in many setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin construction for rigidity and wear resistance in precision cutting applications\u003c\/li\u003e\n\u003cli\u003e0.01 inch corner radius reduces stress risers and produces consistent edge breaks on machined parts\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral design supports higher feed rates and improved surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry and ramp milling toolpaths\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish well-suited for non-ferrous and general-purpose milling operations\u003c\/li\u003e\n\u003cli\u003e1\/2 inch shank diameter for standard ER and side-lock toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 1\/2 inch shank diameter end mill with right-hand cutting direction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator following the machine tool manufacturer's toolholding specifications. Ensure the spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Verify runout with a dial indicator after seating to confirm proper tool concentricity before initiating a cut. Consult the machine's programming documentation for appropriate feed, speed, and depth-of-cut parameters for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\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: plus or minus 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\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 0.37 pounds\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: 12183553\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730865914162,"sku":"12183553","price":124.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73c04634520c9c935594d6444966ee6c.jpg?v=1788724089","url":"https:\/\/voomisupply.com\/products\/accupro-12183553-corner-radius-end-mill-1-2-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
