Abstract
A tool for use in installing fasteners in workpieces is disclosed. The tool includes a pintail bore which includes a passage extending through the nose assembly, the piston, and the back cap. An air channel connected to a supply of pressurized air is connected to the pintail bore. An air restriction mechanism blocks the flow of air out the nose of the tool and a pintail retaining device prevents detached pintails from exiting out the nose of the tool. Thus, pressurized air flowing through the air channel carries detached pintails out the pintail bore to a pintail collection chamber.
