Manufactured from M42 cobalt high-speed steel, it delivers heat and wear resistance in tough ferrous and stainless materials. The tool runs a 3-degree taper per side with a 3\/8-inch small end diameter and a 2-1\/4-inch length of cut, giving machinists the reach and geometry needed for core and cavity profiling. With 3 spiral flutes and a right-hand flute direction, it evacuates chips efficiently while maintaining good surface finish. The square end configuration suits slotting, ramping, and finishing passes in tapered pocket applications.\u003c\/p\u003e\u003cp\u003eThis tapered end mill is suited for job shops, tool and die operations, and mold-making environments running conventional vertical or CNC milling machines. It fits applications in steel, stainless, cast iron, and similar hard materials where M42 cobalt provides an edge over standard M2 tooling. The 5\/8-inch shank mounts in standard ER collet chucks, side-lock holders, or Weldon-style tool holders commonly used in production and prototype machining. The uncoated finish makes it easy to resharpen when needed. This tool belongs to OSG Series 594.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-degree taper per side for accurate draft and angled wall geometry\u003c\/li\u003e\n\u003cli\u003eM42 cobalt construction for improved hot hardness over standard HSS\u003c\/li\u003e\n\u003cli\u003e3 spiral flutes with right-hand cut for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003e25-degree helix angle balances cutting efficiency and edge stability\u003c\/li\u003e\n\u003cli\u003eSquare end profile for flat-bottom slotting and profiling passes\u003c\/li\u003e\n\u003cli\u003eUncoated finish allows straightforward resharpening on tool and cutter grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or equivalent tapered end mill for milling operations requiring a 3-degree-per-side taper, 3\/8-inch small diameter, and 5\/8-inch shank in Series 594 tooling programs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following shop tooling procedures. Secure the 5\/8-inch shank firmly in a properly sized collet chuck or end mill holder and verify runout with a dial indicator before cutting. Ensure the machine spindle is fully stopped before tool changes. Follow the machine tool manufacturer's recommended speeds and feeds for cobalt tooling in the workpiece material being cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 594\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 3\/8 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/4 inches (2.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 25 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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: 5947200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734735061298,"sku":"5947200","price":151.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bfdbb1de45504637b6a93b37be5c4d7.jpg?v=1788766329","url":"https:\/\/voomisupply.com\/products\/osg-5947200-tapered-end-mill-3-flutes-cobalt-square-end","provider":"Voomi Supply","version":"1.0","type":"link"}
