  • High speed steel costs less than carbide and cobalt while providing good wear resistance.
  • Produces a finer finish than end mills with two or three flutes.
  • Double end provides twice the cutting ends and offers convenience to always have a spare tool on hand.
  • Multiple flutes allow for faster reeds at the expense of chip removal due to the reduced area of flute space.


  • Commonly used for general purpose milling of both ferrous and non-ferrous materials.
