摘要

The holder (1) has a passage (8), and a chisel (3) is fastened on the chisel holder, where the holder and the chisel have tungsten-carbide-sinter metals (2, 4). The outer edges of the chisel are rotated at 90 degree according to the wear. The sinter metal on the holder has a projection opposite to the outer contours of the holder to avoid a friction on the tool, such that the chisel is not pulled out from the holder.
