Built from M42 high-speed cobalt steel, it delivers heat resistance and edge retention in demanding cutting environments. The tool measures 0.3346 inches in diameter with a 9\/16-inch length of cut and a 3\/8-inch shank diameter. A 30-degree right-hand spiral flute geometry promotes efficient chip evacuation, while the centercutting design allows the tool to plunge directly into a workpiece. This end mill ships uncoated and is well suited for machinists, tool-and-die makers, and job shop operators running manual or CNC milling equipment.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard milling applications where a sub-half-inch diameter tool is required. The 3\/8-inch shank seats in common ER or side-lock collet systems. With an overall length of 2-5\/16 inches and a regular-length classification, it suits typical shallow-to-mid-depth slotting, profiling, and pocketing work on mills and machining centers. The Series 580 designation places it within OSG's standard cobalt end mill lineup, making it a reliable choice for production shops and maintenance machining alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction provides elevated heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flute promotes positive chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eTwo-flute geometry leaves more chip clearance, ideal for softer or gummy materials\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows easy regrinding and suits applications where coating adhesion is a concern\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration matches standard spindle rotation on most milling machines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank replacement end mill for use in 3\/8-inch collet chucks, ER collet systems, or side-lock holders on manual knee mills and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard tool-change procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank to the full recommended engagement depth in the collet or holder and torque the retention nut to the collet manufacturer's specification. Verify runout with a dial indicator before initiating a cut, as excessive runout accelerates wear on a two-flute tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3346 inches (8.50 mm)\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: 0.5625 inches (9\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 580\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: 5808600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736188354866,"sku":"5808600","price":47.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05b6af40a5264ca5e9e7720c7369d3f0.jpg?v=1788776423","url":"https:\/\/voomisupply.com\/products\/osg-5808600-square-end-mill-0-3346-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
