Ground from 3% vanadium high speed steel, it delivers improved wear resistance and edge retention compared to standard M2 HSS. The cutter measures 5\/32 inches in diameter with a 7\/16-inch length of cut and mounts on a 3\/8-inch shank. Overall length is 2-3\/8 inches. The 30-degree spiral helix promotes efficient chip evacuation, and the centercutting geometry allows plunge entry. This tool is installed and operated by machinists and CNC operators in job shop and production settings.\u003c\/p\u003e\u003cp\u003eThe 5740200 is suited for milling ferrous and non-ferrous materials in light-to-medium-duty applications where HSS tooling is preferred over carbide. The regular-length body and 3\/8-inch shank make it compatible with standard end mill holders and collet chucks on vertical mills, knee mills, and CNC machining centers. Right-hand cut and right-hand flute configuration is the industry standard for conventional and climb milling passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/32-inch (0.1563 inch) diameter with 7\/16-inch (0.4375 inch) length of cut\u003c\/li\u003e\n\u003cli\u003e3% vanadium high speed steel construction for extended edge life over M2 HSS\u003c\/li\u003e\n\u003cli\u003e4 flutes with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows axial plunge entry without pilot drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute spiral geometry\u003c\/li\u003e\n\u003cli\u003eUncoated finish; regular-length Series 574 profile\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank replacement end mill compatible with 3\/8-inch end mill holders, collet chucks, and milling machines accepting right-hand tooling of this diameter and shank size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed and changed by machinists using appropriate end mill holders or collet chucks; ensure the machine spindle is fully stopped and locked out before any tool change. Verify holder bore diameter matches the 3\/8-inch shank before clamping. Follow the machine tool manufacturer guidelines for runout tolerance and pull-out prevention. Inspect the cutting edges for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Vanadium High Speed Steel (3% Vanadium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 5740200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51750667714866,"sku":"5740200","price":41.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00e2c7e6066d89a2e764e515963a1840.jpg?v=1788918133","url":"https:\/\/voomisupply.com\/products\/osg-5740200-square-end-mill-5-32-in-4-flute-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
