A digging tool has a shaft with a proximal end and a distal end. The proximal end has at least one beveled surface for engaging with a drill chuck. An eggbeater-shaped digging body is coupled to the shaft. The digging body is formed from a plurality of bands that intersect each other at an intersection region at the distal end of the shaft. The bands are welded to each other and to the shaft at the intersection region and form a plurality of substantially U-shaped digging surfaces. Each U-shaped digging surface has a distal arm coupled to the intersection region and a proximal arm coupled to the shaft between the intersection region and the proximal end of the shaft. A protective cover is welded to the intersection region to cover the intersection region. The protective cover preferably includes a distally extending non-puncturing tip.
