Built from M42 cobalt high-speed steel, it delivers improved heat and wear resistance compared to standard HSS tooling. The cutter measures 5\/32 inch (0.1563 inch) in diameter with a 7\/16 inch (0.4375 inch) length of cut and a 30-degree right-hand spiral helix. Four flutes provide a balance of chip evacuation and surface finish. The double-end configuration extends tool life by offering two usable cutting ends per tool. Licensed machinists and tool-and-die professionals are the primary installers of this tooling.\u003c\/p\u003e\u003cp\u003eThe OSG 5677800 is suited for general-purpose slotting, profiling, and peripheral milling in job shops, maintenance machining, and production environments. Its regular-length geometry fits standard collet and end mill holders for vertical machining centers and knee mills. The bright, uncoated finish makes it a practical choice for operations where coolant is used, and the center-cutting design allows it to plunge directly into the workpiece without pre-drilling. Series 567 from OSG is positioned for versatile ferrous cutting across a range of steel alloys and stainless steels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved heat resistance and tool life in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool, extending service life\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand spiral helix balances chip flow and cutting forces\u003c\/li\u003e\n\u003cli\u003eFour-flute configuration suits finishing and semi-finishing passes\u003c\/li\u003e\n\u003cli\u003eBright, uncoated surface finish compatible with flood coolant and cutting oil\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for use in collet chucks, end mill holders, and Weldon-style holders accepting a 3\/16 inch shank diameter, consistent with Series 567 regular-length square end mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with speeds, feeds, and proper clamping for small-diameter end mills. Secure the shank fully within the holder to the recommended engagement depth before tightening; insufficient grip on a small-diameter tool increases deflection risk. Power down the spindle and confirm the machine is in a safe state before changing tooling. Follow shop safety practices and machine manufacturer guidelines when setting depth of cut and feed rate for cobalt tooling in hardened or stainless materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 567\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5677800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51750452724018,"sku":"5677800","price":63.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5b57ccb16e387844d4a68dcf9aba720.jpg?v=1788915574","url":"https:\/\/voomisupply.com\/products\/osg-5677800-square-end-mill-5-32-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
