Take the Plunge: Drill vs. Mill : MoldMaking Technology

A mill of similar size will have more effective cutting edges, since all cutting edges are cutting the same path, and this can greatly increase the feed rate per minute, bringing the material removal rate (MRR) closer to that of a drill, even though less material is being removed per pass. In some cases, the MRR may even be greater.
