An impact tool includes a cylindrical body having an internal chamber, a piston assembly positioned within the internal chamber, the piston assembly having a piston base and a piston rod, an adapter arranged on the cylindrical body and having external threads, and a location tip assembly having an opening and having internal threads couplable to the adapter by engaging the external threads relative to the internal threads to create a threaded connection, the threaded connection allows the location tip assembly to be moved axially to a selectable height. An impact tip coupled to an end of the piston rod. Upon introduction of pressurized air within the internal chamber, the piston assembly moves axially towards the adapter causing the impact tip to move axially through the opening towards a surface resulting in impact with the surface to be dented.
