PROBLEM TO BE SOLVED: To prevent set values such as torque or rotational frequency from being changed inadvertently. SOLUTION: A power tool of the embodiment comprises a tool body A whose set values of torque and rotational frequency are variable, and a setting device B for setting the set values of the tool body A. Since the set values (set torque value and set rotational frequency value) stored in a memory 3 of the tool body A can be set only by the setting device B separate from the tool body A, the set values such as the torque or the rotational frequency are not inadvertently changed during operation unlike conventional ones. As a result, reliability in operation such as torque control, and working efficiency are improved. COPYRIGHT: (C)2008,JPO&INPIT
