An example drill bit includes a body that is connectable to a drill string. The body has a base configured to face downhole within a wellbore and a perimeter configured to face a wall of the wellbore. The body includes a first nozzle and a second nozzle. The first nozzle corresponds to a first channel that exits the body through the perimeter and the second nozzle corresponds to a second channel that exits the body through the base. The example drill bit also includes a bit cutter on the base of the body and a valve within the body. The valve is configured to move within the body to block either the first channel or the second channel.
