Claim 12:
13. A driver drill comprising:
a motor housing that holds an electric motor, an axis of rotation of a rotor of the electric motor extending in a front-rear direction of the driver drill;
a grip housing having an upper end connected to a lower part of the motor housing; and
an enlarged-part housing connected to a lower end of the grip housing and being spaced from the motor housing in an up-down direction of the driver drill that is perpendicular to the front-rear direction;
wherein:
the driver drill is shiftable between a torque-threshold-setting unlocked state in which an electronically settable torque threshold setting of the driver drill is changeable by an electric signal and a torque-threshold-setting locked state in which the electronically settable torque threshold setting of the driver drill is not changeable; and
the driver drill is configured to electronically switch from the torque-threshold-setting unlocked state to the torque-threshold-setting locked state after a predetermined time has elapsed from initiation of the torque-threshold-setting unlocked state.
