With a 5\/16-inch mill diameter and 7\/16-inch length of cut, this stub-length tool delivers rigidity and reduced deflection in tight-reach applications. The 3-flute, right-hand spiral geometry with a 60-degree helix angle promotes aggressive chip evacuation and efficient cutting at higher feed rates. Micrograin carbide construction provides hardness and wear resistance across a range of workpiece materials. The bright\/uncoated finish is suitable for general-purpose milling where coating-related heat buildup is a concern.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers, vertical mills, and manual milling setups where a stub-length tool is preferred for increased rigidity. The double-end configuration extends tool life by providing two usable cutting ends. Typical applications include slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The centercutting design allows plunge entry into workpieces without pre-drilling. This tool is installed and operated by machinists and toolroom professionals working in job shops, production machining, and maintenance environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design provides two cutting ends, extending usable tool life\u003c\/li\u003e\n\u003cli\u003e60-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction delivers hardness and dimensional stability\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pilot hole\u003c\/li\u003e\n\u003cli\u003eStub-length classification reduces deflection in short-reach milling applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit cutting tool for standard 5\/16-inch collet or end mill holder tooling systems used in CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank in a properly sized collet, end mill holder, or set-screw holder, verifying that runout is within acceptable limits before cutting. Inspect both cutting ends for chipping or wear before use and do not exceed the tool manufacturer recommended depth-of-cut 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: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 60 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 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\u003eWeight\u003c\/strong\u003e: 0.5 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: 2500238\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744027705650,"sku":"2500238","price":85.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61090563e92258f6ea83760605313bbd.jpg?v=1788853164","url":"https:\/\/voomisupply.com\/products\/accupro-2500238-square-end-mill-5-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
