Abstract
There is shown a tool holder for a hob, which is embodied as a bore having a clamping device provided between a spindle and a counterholder, the clamping device having a centring clamping piece that is engageable in the hob and a receiving mandrel that is engageable in the hob, the receiving mandrel being braced with the centring clamping piece in order to mount the hob, wherein the centring clamping piece has a flange. In order to ensure the best concentric running properties in a stable manner, it is proposed that the centring clamping piece and the receiving mandrel each have a flange, which each mount a radial adjusting drive with at least one adjusting member that is adjustable with respect to the spindle and/or the counterholder in order to center the clamping device.
