A dome reamer drill bit functions to enlarge a borehole and it is designed with a drill portion and a reamer portion. The drill portion is formed by cutting edges at the end of a plurality of flutes, and the reamer portion includes a first relief formed on each flute surface disposed at a predetermined angle with respect to the flute surface to form a first reamer cutting edge. A second relief is formed contiguous with the first face on each reamer portion and is disposed at a second angle, less than the first angle with respect to the flute surface
