Abstract

The invention relates to a shank, a rock drill and a method for drilling rock. In the invention, a percussion element (1) of the rock drill (21) is arranged to strike the shank (2) having an impact surface (8) at a distance from its (2) back end (13). Then, at least at the time of impact, the percussion element (1) and said back end (13) are at least partly inside each other.
