Abstract
An explosive powder charge operated setting tool drives fastening elements, such as bolts, nails, and the like into hard receiving materials. The setting tool has a housing (1) with a piston guide (2) including a cartridge chamber (6) axially displaceable in the housing. A driving piston (4) is axially displaceable in a guide bore (5) in the piston guide. A firing pin guide (3) is located in the housing rearwardly of the piston guide and is displaceable parallel to the driving direction of the tool. An inertia mass (12) cooperates with a control member (17) for regulating the power output of the tool.
