Built from micrograin carbide, it delivers a rigid cutting edge suited to high-tolerance work in steel, aluminum, and similar machinable materials. The 4-flute configuration balances chip evacuation with surface finish quality, while the 30-degree helix angle promotes smooth cutting action and reduced vibration. With a 9\/16 inch cutting diameter and 1-1\/8 inch length of cut, this tool handles slotting, profiling, and peripheral milling in a single-end, centercutting configuration. It is installed by machinists and CNC operators on vertical mills and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits applications where a standard-reach, right-hand cut tool is required. The 9\/16 inch shank diameter matches the cutter diameter, allowing direct chuck or collet mounting without a reduction bushing. The 3-1\/2 inch overall length keeps the tool compact for general-purpose work, reducing deflection in typical cavity and contour milling scenarios. The uncoated finish makes it suitable for use in both dry and lubricated cutting environments, depending on workpiece material and shop practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with 30-degree helix angle for smooth chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish compatible with a broad range of workpiece materials and cutting fluids\u003c\/li\u003e\n  \u003cli\u003eRegular length type with matched shank and cutter diameter for direct collet mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tool for standard 9\/16 inch collet or chuck systems on vertical milling machines and CNC machining centers requiring a 4-flute square end mill in the OSG Series 404.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. The machine spindle must be fully stopped and the tool-change procedure completed before mounting or removing the end mill. Secure the shank in a properly sized collet or end mill holder to the torque specification listed by the toolholder manufacturer. Inspect the cutting edges for chips or damage before each use, and confirm runout with a dial indicator when tolerance work is involved.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inch (1.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/16 inch (0.5625 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.47 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 404-5625\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732054868274,"sku":"404-5625","price":109.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74a4e2dc460f395e968e01e201679602.jpg?v=1788738703","url":"https:\/\/voomisupply.com\/products\/osg-404-5625-square-end-mill-9-16-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
