2. Brief Introduction
For use in cleaning material from the hole that augers cannot retrieve. The operator simply put the tool into the hole with the door open, lower to the bottom of the hole making only a few revolutions before placing the machine in reverse to close the door. Because the tool is vented, the operator simply pull the tool up to the top of the shaft, lower the tool to the ground and place drill in forward to open the door.
