Built from M42 high-cobalt steel, this tool delivers strong heat and wear resistance in demanding cutting environments. The square end geometry and 3-flute spiral design produce clean, accurate finishes on a wide range of ferrous and non-ferrous materials. With a 3\/8-inch small end diameter, a 2-degree taper angle per side, and a 1-1\/4-inch length of cut, the 5937100 suits tight-tolerance slotting, draft-angle milling, and die-work applications where consistent taper geometry is critical.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in mold and die work, general machining, and production environments where tapered wall features are required. The right-hand flute direction and 25-degree helix angle support efficient chip evacuation in both conventional and climb milling setups. It is sized for use in standard 1\/2-inch shank tool holders and is appropriate for manual mills, CNC machining centers, and knee mills running at appropriate speeds and feeds for cobalt tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved heat resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e2-degree taper angle per side for consistent draft and taper-wall geometry\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design promotes efficient chip removal and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eSquare end profile for flat-bottom slots and stepped features\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eUncoated finish — suitable for re-sharpening and use with cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/2-inch shank tool holders across CNC machining centers and manual milling machines.

Seat the 1\/2-inch shank fully in the tool holder and torque the collet or set screw to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut. Speeds and feeds should be selected based on workpiece material and machine rigidity per standard cobalt tooling guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eTaper Angle Per Side\u003c\/strong\u003e: 2 degrees\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\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/4 inches\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 593\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: 5937100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731186876722,"sku":"5937100","price":119.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f3168672cc73e67853835bbde0f2fe3.jpg?v=1788728073","url":"https:\/\/voomisupply.com\/products\/osg-5937100-tapered-end-mill-3-flute-cobalt-square-end","provider":"Voomi Supply","version":"1.0","type":"link"}
