Patent ID: 8796976

Claim:
An electric power tool comprising: a motor that is configured to rotationally drive an output shaft on which a tool element can be removably mounted; an operation unit configured to input a drive command of the motor by an external operation; a torque setting device that sets a forward upper limit value and a reverse upper limit value of a rotational torque of the output shaft in accordance with a torque setting command inputted externally, the forward and reverse upper limit values corresponding to upper limit rotational torque values of the output shaft in respective forward and reverse rotational directions of the output shaft; and a control device that drives the motor in one of a forward direction and a reverse direction in accordance with the drive command from the operation unit, and stops driving of the motor when the rotational torque of the output shaft has reached the forward or reverse upper limit value set by the torque setting device during driving of the motor in respective forward or reverse directions, wherein the torque setting device is configured to set the the forward upper limit value to be different from the reverse upper limit value for a given torque setting.
