  "abstract": "Provided is an impact tool capable of stopping or decelerating a motor even if seating has occurred before impacting starts. An electric tool, which is an impact tool, includes: a motor; an impact mechanism driven by the motor; a current measuring means for measuring a motor current; a rotation speed measuring means for detecting a motor rotation speed; and a control unit for controlling the motor. The control unit includes a seating determination mode configured to determine whether a screw is seated, in accordance with the measured motor current and motor rotation speed, at any time point before or after impacting by the impact mechanism is started in a screw tightening operation having multiple different work conditions, and to stop or decelerate the motor after it has been determined that the screw is seated.",
