Claim 1:
2. The induction heating device according to claim 1, wherein the electric supply unit is configured to operate the two inductors differently in such a way that an energy input into a first subregion of a tool holder, which is arranged around a receiving region of the tool holder and is in a heating operation encompassed by one of the inductors, is balanced with an energy input into a second subregion of the tool holder, which is also arranged around the receiving region of the tool holder and is in the heating operation encompassed by the other one of the inductors, as a result of which in the heating operation a radial expansion of the entire receiving region of the tool holder is identical in both subregions.
