Abstract
The invention relates to a bit holder having an insertion projection and having a bore-shaped bit receptacle that has a longitudinal center axis, a convexly curved support surface being provided on a base part. A bit holder of this kind can be implemented in compact and stable fashion in particular by the fact that the longitudinal center axis of the bit receptacle intersects the support surface.
