Abstract (en)
[origin: WO2012072785A2] The invention relates to a chisel holder for a ground processing machine, in particular a road miller, comprising a supporting member to which a plug-in attachment is indirectly or directly connected at a plug-in attachment end. The plug-in attachment has at least one convex contact surface and a pressure surface. In order to deflect the processing forces in such a chisel holder in an optimized manner with respect to the load conditions, the plug-in attachment has two convex contact surfaces that are located at a distance from each other.
