A power tool (1) has a continuously variable transmission (7), status detection devices (J1-J3, J5), and an operation control device (C0). The continuously variable transmission (7) changes the speed of the rotational output from a drive motor (6) and outputs same to a spindle (9) to which a tip tool is attached. The status detection devices (J1-J3, J5) detect the status of the power tool (1). The operation control device (C0) determines a target rotation speed for the spindle (9) on the basis of the status of the power tool (1) detected by the status detection devices (J1-J3, J5), and controls the rotation speed of the drive motor (6) and/or the gear-change ratio of the continuously variable transmission (7) on the basis of the target rotation speed. |
