It features a 5\/8 inch diameter with a 0.015 inch corner radius that reduces stress concentrations at the cutting edge, extending tool life in demanding applications. The 4-flute, right-hand spiral configuration paired with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. A TiCN coating adds wear resistance and reduces friction at the cutting zone. This tool is a single-end, centercutting design, meaning it can be plunged directly into the workpiece. Machinists, tool-and-die makers, and CNC operators install and run this tool in vertical and horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for profiling, slotting, and finish milling operations where a small corner radius is required to maintain part geometry while reducing edge chipping. The 1-1\/4 inch length of cut and 3-1\/2 inch overall length make it appropriate for moderate-depth cavity work and side-wall milling in mold and die, aerospace, and general precision machining environments. The 5\/8 inch shank diameter provides positive clamping in standard ER and side-lock toolholders. Right-hand cutting direction is standard for conventional CNC milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.015 inch corner radius reduces stress risers and edge breakout on finished profiles\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance and surface lubricity for extended tool life\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and cutting direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers and manual mills accepting a 5\/8 inch shank diameter toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the full recommended engagement depth in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning a production cut, particularly given the close shank diameter tolerance of -0.0001 to -0.0004 inches.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eCorner Radius\u003c\/strong\u003e: 0.015 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.5000 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 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: 12182631\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727355609394,"sku":"12182631","price":172.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84cfd94ae382291025d9f8962ceb89de.jpg?v=1788676654","url":"https:\/\/voomisupply.com\/products\/accupro-12182631-corner-radius-end-mill-5-8-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
