Abstract: A driver-drill (1) includes a motor (6) having a stator (61) and a rotor (62); an output part (8) including: a spindle (81), which is disposed more forward than the motor and, in response to application of a rotational force transmitted from the rotor, is rotated around a rotational axis (AX) extending in the front-rear direction; and a chuck (82), which is mounted on the spindle; and a speed-reducing mechanism (30), which is configured to rotate the output part at a rotational speed that is lower than the rotational speed of the rotor but at a higher torque. The maximum fastening torque of the output part is 160 N·m or more.
