Abstract
A setting tool for driving fastening elements in a constructional component includes piston stop device for braking the setting piston, and is located at an end region of the hollow chamber of the piston guide in which the setting piston is displaceable, and has a damping element supported against a bottom, a stop element for the setting piston and adjoining the damping element in a direction of the hollow chamber, and an inertia body cooperating with the stop element and displaceable in a direction parallel to a longitudinal extent of the setting piston between first and second stops both of which are connected with the stop element and a distance between which, in a direction parallel to the longitudinal extent of the setting piston, is greater than a length of the inertia body in a same direction by length of a decoupling path.
