Uncoated Carbide Tapered Square End Mill

Manufacturer part: 8946A114

Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. Also known as taper degree end mills, they're often used to machine angled slots in dies and molds.End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.Noncenter-cutting end mills are for operations where the peripheral teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts.
