Built from M42 cobalt high-speed steel, it delivers strong heat and wear resistance in demanding cutting applications. The tool features a 10-degree taper angle per side with a 1\/8-inch small end diameter and a 1-1\/4-inch length of cut. Three right-hand spiral flutes with a 25-degree helix angle promote efficient chip evacuation and a smooth cutting action. The bright, uncoated finish suits applications where coating buildup or thermal interaction with the workpiece is a concern. Machinists and tool-and-die professionals install this end mill in standard milling machines and CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis tapered end mill is suited for mold and die work, dovetail-adjacent profiling, and any application requiring a precise tapered wall or draft-angle feature in ferrous and non-ferrous materials. The 5\/8-inch shank diameter fits standard collets and end mill holders on vertical milling machines and CNC machining centers. The 3-3\/8-inch overall length provides adequate reach for moderate-depth cavity work without excessive deflection. The center-cutting geometry allows plunge entry where the job requires it, adding versatility in multi-step milling programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-degree taper angle per side for consistent draft-angle profiling\u003c\/li\u003e\n  \u003cli\u003eM42 cobalt construction for superior heat resistance compared to standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003e3 right-hand spiral flutes with 25-degree helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable for direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for compatibility with a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch shank diameter fits common collet and end mill holder sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard collets and end mill holders accepting a 5\/8-inch shank diameter; part of OSG Series 597 tapered end mill lineup.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a properly sized collet or end mill holder rated for the 5\/8-inch shank before securing in the spindle. Ensure the machine spindle and workpiece are fully stationary before mounting or removing the tool. A licensed machinist or trained CNC operator should verify speeds and feeds for the specific workpiece material before running. Inspect the cutting edges for chipping or wear before each use and replace when cutting performance degrades.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1\/8 inches (3.17 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: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 25 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 597\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: 5974500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746454438194,"sku":"5974500","price":147.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f059368429740ae9a8737ce93e52642b.jpg?v=1788870417","url":"https:\/\/voomisupply.com\/products\/osg-5974500-tapered-end-mill-3-flute-cobalt-square-end","provider":"Voomi Supply","version":"1.0","type":"link"}
