Built from M42 cobalt high-speed steel, it delivers heat and wear resistance well above standard HSS tools. The TiN (titanium nitride) coating further extends tool life by reducing friction and increasing surface hardness. At 0.625 inches in diameter with a 1.125-inch length of cut and a 4.5-inch overall length, this tool fits standard 5\/8-inch collets and toolholders. It is installed and operated by machinists and tool-and-die professionals in job shop, maintenance, and production environments.\u003c\/p\u003e\n\u003cp\u003eThe 5222105 is suited for slotting, profiling, and peripheral milling operations on steel, stainless, cast iron, and high-temperature alloys where standard M2 HSS tooling runs short on tool life. Its centercutting geometry allows plunge milling in addition to lateral passes. The 30-degree right-hand spiral helix promotes smooth chip evacuation and reduces chatter during interrupted cuts. The double-end configuration provides a second cutting end, extending the usable life of each tool before replacement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for elevated heat resistance and hardness retention\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eDouble-end configuration doubles usable tool life per piece\u003c\/li\u003e\n  \u003cli\u003eRegular length geometry fits standard collet and toolholder setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for machining centers, knee mills, and manual mills accepting a 5\/8-inch shank diameter in the OSG Series 522 product line.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eEnd mills should be installed by qualified machinists following standard toolholding procedures. Secure the shank fully into the collet or toolholder to the recommended engagement depth before tightening. Inspect the collet and toolholder for runout before use, as excessive runout accelerates edge wear and reduces dimensional accuracy. Never exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eDouble End\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 522\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5222105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730917720370,"sku":"5222105","price":173.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e6d13d97cdc09729cd06f1a71ef7919.jpg?v=1788724769","url":"https:\/\/voomisupply.com\/products\/osg-5222105-square-end-mill-5-8-in-2-flute-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
