Drilling tools include a bit crown and an integrated reamer. The bit crown and the integrated reamer can be configured with approximately equal drilling lives. The bit crown can be impregnated with abrasive cutting media and include one or more external flutes. The integrated reamer can be positioned at the base the bit crown and include one or more channels that align with one or more of the outer flutes. The channels can taper such that they increase in width as they extend away from the bit crown.
