A working tool and a control system provided with the same

SUBJECT of the Invention The working tool which can estimate the load apply|hang|started on a motor with high precision， and a control system provided with the same are provided. PROBLEM to be solved The working tool 10 is provided with the motor 111， the trigger switch 121， and the measurement part 16 (load estimation part 161). The trigger switch 121 is operated by the operator and adjusts the output of the motor 111 according to operation amount. The measurement part 16 calculates the presumed load information apply|hang|started on the motor 111 based on the motor current input into the motor 111， and the rotational speed of the motor 111.
