Auger drilling is a fast and inexpensive method utilized primarily in soft, unconsolidated formations and weak, weathered rock. Performed using a helical blade that is drilled into the ground using rotation and down pressure, earth is moved up the borehole as the blade advances. This is a preferred drilling method when depth, ground conditions and sample quality are not critical.
