Abstract
An explosive powder charge operated setting tool includes a driving piston (1) positioned in an axially extending piston guide (4) with a base surface (5) at a trailing end of the piston guide. A spacer (2) is located on the trailing end surface of the piston (1) and projects axially from its trailing end surface. The spacer (2) has a stop face (3) extending perpendicularly of the piston guide axis with a surface area smaller than the area of the base surface (5) against which it contacts.
