ABSTRACT:
A soil auger particularly useful for removing a quantity of soil as a plug is provided, and is particularly adapted for use with a portable electric drill. The auger body is substantially cylindrical with at least one open end and provides a balanced unit for use at high rotational speeds. A series of teeth at the lower margin of the auger are alternately inwardly and outwardly displaced from the plane of the cylinder. The teeth may extend completely around the lower margin or only a portion thereof. Offset apertures in the walls of the cylinder permit removal of the soil contained therein. A shaft is mounted at the end of the auger opposite the teeth and adapted to be coupled to a hand held electric drill. In operation, the soil auger enters the ground driven by the drill which rotates the auger. The teeth of the auger create a circular hole in the ground around a plug of soil, the plug of soil entering the interior of the auger body for subsequent removal.
