A friction stir welding tool for a machine tool having a frame and a spindle rotatable relative to the frame. The friction stir welding tool includes a pin, a shoulder, and a drive shaft connectable to the spindle to set the pin and shoulder in rotational motion about a rotation axis, wherein the shoulder is rotatable relative to the pin about the rotation axis. To obtain different speeds of the pin and shoulder in a simple and robust manner, a planetary transmission having a ring gear, a planet carrier, and a sun gear is connected to the drive shaft, pin, and shoulder. The pin or the shoulder is connected to the planet carrier so that the pin and shoulder are set in rotation about the rotation axis at different rotational speeds, but in the same rotation direction, by driving the drive shaft by the spindle.
