摘要： The subject matter of the invention is a bit holder for an earth working machine, in particular a road milling machine, having a support member onto which an insertion projection is indirectly or directly attached on an insertion projection side, the insertion projection comprising at least one convex abutment surface and one pressure surface. In a bit holder of this kind, working forces can be dissipated in stress-optimized fashion into an attached base part when provision is made that the insertion projection comprises two convex abutment surfaces that are arranged at a distance from one another.

摘要： 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.

摘要： The invention relates to a bit holder for an earth working machine, in particular a road milling machine, that comprises a bit receptacle in the region of a working side of a support member and that indirectly or directly carries an insertion projection on an insertion projection side of the support member, the support member comprising two stripping surfaces [first or second stripping surfaces] that form a stripping surface pair and are at an angle to one another. In order to achieve a stable and long-lived configuration with such a bit holder, provision is made according to the present invention that the support member comprises at least one further stripping surface that is at an angle to the two stripping surfaces of the stripping surface pair.
