    Use these end mills for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. They have a square end for milling square slots, pockets, and edges.
    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.
    Uncoated High-Speed Steel—Use uncoated end mills for general purpose milling and short production runs.
    Titanium Nitride (TiN)-Coated High-Speed Steel—Use titanium nitride (TiN)-coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills, which means they last longer when run at similar speeds.
    Center Cutting—Center-cutting end mills allow plunge cuts into a surface.
