Abstract
The portable power chiseling tool has a tool holder, an electric motor, a striking mechanism and an idle strike catcher. The tool holder can receive a tool and retain it movably on a working axis. The striking mechanism includes an exciter piston, a striker, an anvil and a guide for the anvil. The exciter piston is coupled to the electric motor. The guide guides the anvil on the working axis. The idle strike catcher for the anvil has a conical inner surface facing the anvil. The anvil has an associated end face facing in the striking direction. The end face rests against the conical inner surface when the anvil is in its forwardmost position in the striking direction. The end face of the anvil has a first segment and a second segment in the circumferential direction. The second segment is offset in the striking direction relative to the first segment.
