It is built from 3 percent vanadium high speed steel, which provides improved wear resistance and toughness compared to standard M2 HSS. The cutting end carries a TiCN (titanium carbonitride) finish that further extends tool life by reducing friction and heat buildup at the cutting edge. At 0.375 inches in diameter with a 0.5625-inch length of cut and a 30-degree helix angle, this tool is well suited for slotting, profiling, and peripheral milling in machining centers and manual mills. It is centercutting, allowing direct plunge entry into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard milling applications in job shops, production facilities, and tool rooms. The 0.375-inch shank diameter seats directly in common ER collet chucks, end mill holders, or Weldon-style holders. The 2-5\/16-inch overall length keeps the tool rigid in typical setups, minimizing deflection during side-milling passes. The two-flute geometry provides adequate chip clearance when cutting softer steels, aluminum, and similar materials at moderate feed rates. Series 573 is OSG's regular-length, spiral-flute HSS offering intended for general-purpose material removal where carbide tooling is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3 percent vanadium high speed steel construction for improved edge toughness over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends cutting life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flute promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eTwo-flute configuration maximizes chip clearance for softer workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular-length Series 573 geometry suits a wide range of general milling tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or standard-stock square end mill for use in manual knee mills, CNC vertical machining centers, and similar setups that accept a 3\/8-inch shank diameter toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. The shank should be clean and free of burrs before seating in the holder, and the collet or set-screw holder should be torqued per the toolholder manufacturer's specification. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing end mills. Do not exceed the recommended depth of cut for the diameter and material combination to avoid tool deflection or breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5625 inches (9\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eEnd Type\u003c\/strong\u003e: Single End\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: 573\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 5730908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753194029362,"sku":"5730908","price":48.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76efbbdfaa13a08149cfeb78e243fa5c.jpg?v=1788933729","url":"https:\/\/voomisupply.com\/products\/osg-5730908-square-end-mill-3-8-inch-2-flute-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
