ABSTRACT:
A pneumatic impact tool useful in pipe insertion operations has a simplified construction as compared to the pneumatic ground piercing tools currently in use for such operations. The body of the tool is a thin walled sleeve clamped between a nose section and an end plate by one or more tying devices such as rigid metal tie rods. This eliminates the need for a thick walled tool body having a tapered nose as is common in existing tools made to move through the soil.
