Abstract

An electric tool system includes: a motor; an output shaft to be coupled to a tip tool; a transmission mechanism that transmits motive power of the motor to the output shaft; an acquirer that acquires, based on a current flowing through the motor, a torque value related to output torque provided by the tip tool; and a controller that has a torque management mode in which the controller controls the motor in accordance with an operating command entered by a user through a trigger switch and prevents the torque value from exceeding an upper limit value. The controller controls, when finding a predetermined condition satisfied in the torque management mode, a velocity of the motor into a predetermined restriction value irrespective of a manipulative variable of the trigger switch. The predetermined condition includes a condition that the torque value reach a threshold value smaller than the upper limit value.
