Abstract
A portable marking tool having a cylindrical housing and a concentric cylinder slidably supporting the hammer member for delivering an impact to a marking die. A charge of air is built up in the housing which is suddenly imposed on the piston-like hammer member when the charge of air is built up to overcome a predetermined opposing load. In one embodiment, the opposing load is afforded by a pressure regulated chamber and in another embodiment by an adjustable spring load.
