A drilling tool includes: a drive source; a bit attachment portion to which an end bit is attachable; a power transmission portion configured to apply a motive force to the end bit attached to the bit attachment portion; an operation portion switchable between an ON-state and an OFF-state by a manual operation and configured to receive a setting operation for setting a stop condition; and a controller configured to set the stop condition based on the setting operation, and to start driving of the drive source in response to a first switching operation for switching the operation portion from the OFF-state to the ON-state. In a state where the stop condition is set, even when the operation portion is in the ON-state, the controller stops driving of the drive source in response to the stop condition being met while the drive source is being driven.
