Abstract
The invention relates to an interchangeable chisel holder () which can be fixed to a milling drum () of a ground-working machine (), having a forward chisel holder () for the interchangeable holding of a forward chisel (), preferably a round-shaft chisel, and having a rearward chisel (), which is held on the interchangeable chisel holder (), wherein, as based on a working movement () of the interchangeable chisel holder () when used in the ground-working machine (), the rearward chisel () is arranged behind the forward chisel holder (). In such an interchangeable candleholder () provision can be made, according to the invention, for the rearward chisel () to be held on the interchangeable chisel holder () axially and fixed in the circumferential direction of the chisel holder. Maintenance-induced stoppages of the ground-working machine can thus be reduced and the loss of chisels can at least be lowered.
