Hollow chisel for portable hammer drills

摘要

The invention relates to a hollow chisel for portable hammer drills whose chisel section provided with a flute is bent upwards relative to the longitudinal axis of the chisel shank. In order to improve the guidance of a hollow chisel of this type, the invention provides for a guide element (7) to be attached to at least one lateral boundary wall (6) of the flute (1), which guide element (7) extends outwards roughly at right angles to this wall and in the working position of the chisel comes to bear on the wall (8) to be worked (Fig. 1). <IMAGE>
