1. A tool apparatus with a drivable tool, the tool apparatus comprising a shaft which is coupled to the tool, the tool apparatus further comprising:
at least one braking body,
wherein the tool apparatus is adapted to bring, in the course of a braking procedure, the at least one braking body from a release state into a braking state,
wherein, in the braking state, the at least one braking body is in contact with the shaft and thereby exerts a braking force upon the shaft, so that the shaft and thereby also the tool are braked and
wherein in the release state the at least one braking body is not in contact with the shaft,
wherein the tool apparatus is adapted to bring, in the course of the braking procedure, the one or more braking bodies from the release state into a carry-along state and from the carry-along state into the braking state, wherein, in the carry-along state, the one or more braking bodies are carried along by a movement of the shaft, so that the bringing of the one or more braking bodies into the braking state is assisted by way of the movement of the shaft.
