An acceptable tool.
If you have the spindle speed available to compensate for the fewer cutting edges two flute cutters are better because there is more space for chips in the flutes. Also you can get carbide cutters with a higher angle helix than that and this also helps, but nothing can help better than plenty of cutting fluid of the correct type.
