Abstract (en)
[origin: US6619756B1] A chisel-holder changing system for a road milling machine, a coal cutting machine or the like to which a chisel-holder is fastened in an exchangeable manner by means of a connecting mechanism. The chisel-holder accommodates at least one chisel that can be exchanged. The middle longitudinal axis of the chisel is set at an operating angle of less than 90° with respect to the surface to be worked. In order to be able to obtain varied removal results using such a chisel-holder changing system, the chisel-holder can be fixed in two or more configuring positions to the base part and in different attachment positions of the chisel, the middle longitudinal axis of the chisel is slanted at various working angles.
