Definitions
- EP 201 073 B1 proposed a ring made of elastic plastic in connection with a hard metal ring for the purpose of fixing the chisel, the hard metal ring being intended to secure the chisel in the chisel holder.
- the selected training required a continuous mounting hole in the chisel holder, since the assembly and disassembly of the chisel was only possible from the rear with access to the corresponding hard metal ring.
- the design is such that the depth of the ring groove of the chisel shank exceeds the total thickness of the fastening ring in the area of the ring rib. This ensures that the clip ring for assembly can be reduced in diameter in such a way as to enable the chisel m to be inserted easily
- the inclined surface or end face 18 of the annular rib 16 facing the chisel tip runs parallel to the corresponding inclined surface of the groove 17, so that a corresponding surface contact is ensured, which prevents unintentional loosening of the chisel.
