Zusammenfassung:An example drill bit is formed by a bit head portion and a shank portion. The bit head portion includes a bit face, and the shank includes a bit portion and a bit connection. The bit connection is configured to be coupled to a drill string. The bit head and shank are configured to be secured together. When secured together, one or more blades that start near a central axis of the bit face continue to a gage portion of the bit and along at least a portion of the length of the bit portion of the shank. One or more anchoring elements are coupled to the bit head and the shank to restrict relative rotational or axial movement between the bit head and the shank.
