Setting tool

A setting tool for driving fastening elements in a constructional component, the setting tool comprising:

• a piston guide having a hollow chamber;
• a setting piston axially displaceable in the hollow chamber and having:
• a piston head;
• and
• a piston stem adjoining the piston head;
• a bolt guide adjoining the piston guide in a setting direction of the setting tool;
• and
• a piston stop device for braking the setting piston and located at an end region of the hollow chamber adjacent to the bolt guide, the piston stop device having:
• 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 including:
• an elongate body projecting beyond the stop element in a direction opposite the bolt guide;
• and
• a collar embracing the stop element, with the inertia body cooperating with the stop element and displaceable in a direction parallel to a longitudinal extent of the setting piston between a first stop and a second stop, 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 a length of a decoupling path, wherein the length of the decoupling path is between about 0.2 mm and about 3.0 mm.
