Electric tool

Abstract

An electric tool includes a holder, a motor, a transmission mechanism, a torque detection unit, a clutch mechanism, and a controller. The holder is configured to hold a tip tool thereon. The transmission mechanism transmits torque of the motor to the holder. The torque detection unit detects the torque transmitted from the motor to the holder. The clutch mechanism is switchable from a transmitting state where the torque of the motor is transmitted to the holder to an interrupted state where no torque of the motor is transmitted to the holder, and vice versa. The controller switches, when a predetermined condition about the torque detected by the torque detection unit is satisfied, the clutch mechanism from the transmitting state to the interrupted state.
