It features a 5\/16-inch (0.3125 inch) cutting diameter and a 0.7813-inch length of cut, making it well-suited for slotting, profiling, and peripheral milling operations. The tool runs a 43-degree helix angle, which promotes efficient chip evacuation and smooth cutting action in a wide range of workpiece materials. With a right-hand cut and right-hand flute configuration, it is compatible with standard milling machine setups. The centercutting geometry allows for plunge cutting as well as conventional end milling. Licensed machinists and CNC operators are the primary installers and users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers, vertical mills, and manual knee mills across job shop, production, and toolroom environments. It is appropriate for cutting ferrous and non-ferrous metals, alloys, and similar materials where a solid carbide substrate and a DUROREY coating provide extended tool life and wear resistance. The 5\/16-inch shank diameter fits standard ER collets and end mill holders of the same bore size. The 2-3\/4-inch overall length suits typical shallow-to-medium depth applications where rigidity is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003e43-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables plunge entry as well as standard end milling\u003c\/li\u003e\n\u003cli\u003eDUROREY finish provides enhanced surface hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for compatibility with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eNon-variable helix and non-variable index design for consistent, predictable performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard 5\/16-inch shank end mill holders and ER collet systems requiring a 0.3125-inch bore.

Always power down and lock out the spindle before inserting or removing the end mill from the holder. Ensure the collet or holder is clean and free of debris before seating the shank to the full recommended grip depth. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material being cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7813 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.7000 - 0.8000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 43 degrees\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eFinish\u003c\/strong\u003e: DUROREY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 84401023\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753284075826,"sku":"84401023","price":128.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f792fface2d054f2bdcba680799f2bd_e3ff51e7-f4cb-475a-bfea-f37d2ed98b6c.jpg?v=1788934978","url":"https:\/\/voomisupply.com\/products\/osg-84401023-square-end-mill-5-16-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
