ABSTRACT:
A driving tool and method for injecting fasteners such as nails, or the like into workpieces such as drywall, ceilings or wood for framing a building. The driving tool includes a piston coupled to a rod that is driven forward to engage a head of a nail within a chamber of a barrel and drive the nail out the tool through a nozzle. The tool has a resilient member that is impacted on one end by a piston engaging with the nail to slow the piston's and rod's forward velocity. The resilient member is attached at its other end to a rigid member which is coupled to an indentor. The rigid member stops the forward velocity of the piston head and piston rod to limit the penetration of the nailhead into the drywall while placing an indention in the wall with an indentor. The nozzle is shaped to contact the shank of the fastener as the nail is driven through the tool's chamber to ensure that the nail is maintained perpendicular to the surface of the drywall as the nail exits the tool.
