Abstract:

In one exemplary embodiment of the invention, the device includes an outer housing. The outer housing includes an internal cavity, at least one opening and a distal end. The distal end is configured to be near the construction material during use. The device also includes an internal piston that includes a tip. The internal piston is received within the internal cavity and is configured for reciprocal motion within the outer housing. The device further includes a handle coupled to the outer housing and a trigger mechanism. The trigger mechanism is configured to release pressurized gas within a blast chamber. The pressurized gas drives the internal piston through the opening in the outer housing to produce a hole in the construction material.
