It features a 5\/8-inch mill diameter, a 1-1\/4-inch length of cut, and a 38-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The five-flute, right-hand spiral geometry with a variable index delivers reduced chatter and improved surface finish. An AlCrTiN coating provides thermal resistance and extended tool life in demanding cutting environments. The centercutting design allows plunge entry, giving machinists added flexibility in toolpath programming.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish and semi-finish milling operations in CNC machining centers handling alloy steels, stainless steels, hardened tool steels, and similar materials. The 0.060-inch corner radius reduces stress concentration at the cutting edge, making it appropriate for slotting, profiling, and peripheral milling where edge chipping is a concern. The 5\/8-inch shank diameter fits standard ER or end mill holders commonly found in production and job shop environments. With a 3-1\/2-inch overall length, it handles moderate-reach applications without sacrificing rigidity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-inch mill diameter with matching 5\/8-inch shank for concentric tool holding\u003c\/li\u003e\n\u003cli\u003eFive-flute solid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating for high-temperature performance and extended tool life\u003c\/li\u003e\n\u003cli\u003e0.060-inch corner radius reduces edge chipping in profiling and slotting\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing minimizes vibration and chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production end mill compatible with 5\/8-inch bore end mill holders, collet chucks, and ER tooling systems used in CNC vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Seat the shank to the full recommended gauge length in the holder and torque the retention hardware per the toolholder manufacturer specifications. Inspect the corner radius for chips or coating damage before use, and verify runout with a dial indicator after installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 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\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.060 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 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\u003c\/strong\u003e: AlCrTiN\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 311715\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733106721074,"sku":"311715","price":202.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f79f3165893b166dd8e85757ce7fffc2.jpg?v=1788751441","url":"https:\/\/voomisupply.com\/products\/accupro-311715-corner-radius-end-mill-5-8-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
