Built from M42 cobalt high-speed steel, it delivers greater heat and wear resistance compared to standard HSS tooling, making it well suited for harder workpiece materials and higher cutting speeds. The double-end configuration provides two usable cutting ends, extending tool life between changes. Key dimensions include a 0.1772-inch (4.50 mm) cutting diameter, a 7\/16-inch length of cut, and a 3\/8-inch shank diameter with an overall length of 3-1\/8 inches. The two-flute geometry and 30-degree helix angle promote efficient chip evacuation in a range of materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in general-purpose milling applications including slotting, profiling, and peripheral milling. It is suited for residential machine shops, production floors, and job shops working with ferrous and non-ferrous materials. The centercutting design allows plunge entry directly into the workpiece. The Series 582 designation places it in OSG's regular-length cobalt double-end lineup, appropriate for setups where tool reach is not a limiting factor and a compact, rigid setup is preferred.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for improved heat resistance over standard HSS tooling\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool, reducing per-cut tooling cost\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix spiral flute promotes smooth chip flow and reduces chatter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for standard CNC and manual mill spindles\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with cutting fluids across a range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or production end mill for milling applications requiring a 3\/8-inch shank and 0.1772-inch cutting diameter; compatible with any milling machine or machining center accepting a 3\/8-inch straight shank, including ER collet and end mill holder setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and locked out per applicable machine safety procedures. Ensure the shank is clean and fully seated in the collet or holder before torquing to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut. Do not exceed the tool's rated cutting diameter depth of cut without consulting OSG feeds and speeds data for the Series 582.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1772 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter (mm)\u003c\/strong\u003e: 4.50 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: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 inches\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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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\u003eSeries\u003c\/strong\u003e: 582\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: 5828200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748184490290,"sku":"5828200","price":75.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67d0c42c22e838075677003ee5d03ac9.jpg?v=1788890042","url":"https:\/\/voomisupply.com\/products\/osg-5828200-square-end-mill-0-1772-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
