Abstract (en)
[origin: WO2018121956A1] The invention relates to a tool combination consisting of a chisel holder, which can be fastened to a milling drum of a soil tillage machine, and at least one leading and one trailing chisel, which are retained on the chisel holder, wherein the trailing chisel is arranged after the leading chisel, based on a working movement of the tool combination in use in the soil tillage machine, and wherein each chisel has a chisel tip having a cutter. According to the invention the trailing chisel tip of the trailing chisel has, at least in some areas, a greater hardness than the leading chisel tip of the leading chisel. Thus stoppage times of the soil tillage machine for maintenance can be reduced and the loss of chisels can at least be decreased.
