ABSTRACT:
A sliding-weight operated hole boring tool can be used to make holes of various length or depth in varied soil conditions. A uniquely-shaped tool bit helps to form a smooth, clean hole. In preferred embodiments, detachable elongated stems are used to vary the length of the tool, and water is used to aid boring in hard soil.
