发明名称 Chisel holder system
摘要 A chisel holder system including a base part and a chisel holder. The base part includes a socket wherein the chisel holder with a plug-in insert is introduced. The chisel holder has a bearing surface supported on a supporting surface of the base plate, and the base part has a shoulder connected to the supporting surface. A replacement chamber is formed between the shoulder and a facing end surface of the chisel holder. According to this invention, the supporting surface is placed in the transition region in relation to the shoulder by at least one recess of the shoulder so that the flat-shaped connection between the supporting surface and the shoulder, in the region of the recess, is interrupted in order to optimize the resistance to wear and tear of the base part.
