Built from M42 cobalt high-speed steel, it delivers improved heat and wear resistance compared to standard HSS tooling. The square end geometry and 3-degree taper per side make it well suited for machining tapered slots, die cavities, and draft-angle features. With a 3\/32-inch small end diameter, a 1-inch length of cut, and three right-hand spiral flutes, the tool balances chip evacuation with rigidity on smaller tapered profiles. It is centercutting, allowing plunge entry when the application requires it.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers, manual knee mills, and toolroom applications where tapered wall features must be held to close tolerances. The 3\/8-inch shank diameter fits standard ER and straight-bore collet systems commonly found in both vertical and horizontal milling setups. It is part of OSG Series 594 and is suited for ferrous and non-ferrous workpiece materials. Operators working in tool and die, mold making, and precision part machining will find this geometry particularly relevant.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for increased red hardness and tool life in demanding cuts\u003c\/li\u003e\n\u003cli\u003e3-degree taper per side for accurate draft-angle and tapered slot machining\u003c\/li\u003e\n\u003cli\u003eThree right-hand spiral flutes with 25-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eUncoated finish compatible with a wide range of cutting fluids and materials\u003c\/li\u003e\n\u003cli\u003eSquare end geometry for flat-bottom tapered features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct toolroom selection within OSG Series 594 tapered end mill offerings, compatible with any 3\/8-inch straight-bore or collet chuck holder on standard milling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe state before mounting or changing tooling. Seat the 3\/8-inch shank fully and evenly in the collet or chuck to the recommended engagement depth per the holder manufacturer. Verify runout with a dial indicator before initiating the cut, as excessive runout will accelerate wear on small-diameter tapered end mills.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 594\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eHelix Angle\u003c\/strong\u003e: 25 degrees\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\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: 5942200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747532702002,"sku":"5942200","price":109.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b81bbf8bdfd553c25c6fe47861741b8f.jpg?v=1788882031","url":"https:\/\/voomisupply.com\/products\/osg-5942200-tapered-end-mill-3-flute-cobalt-square-end","provider":"Voomi Supply","version":"1.0","type":"link"}
