8 Sided Hollow Stem Augers from Acker Drill Company

The Hollow Stem Auger is recognized as a versatile, fast, effective tool for advancing the drill hole and "keeping the hole open". Once the drilling depth is achieved, the center stem of the auger is quickly removed and allows working inside the Hollow Stem using coring tools, soil sampling equipment, down-the-hole hammers, or for inserting tie back rods and cables, well points, and drain pipes.
