Most of my drilling is done in rocky soil. What type of auger would you recommend?
The Little Beaver heavy-duty auger, which use Pengo® style teeth, is designed for digging in rocky soil. A variety of points and blades are available to meet specific digging conditions. You may also want to consider using the Little Beaver Hydraulic Earth Drill. It has greater torque output than the mechanical unit and turns at a lower rpm, resulting in less vibration. It will also have a longer service life when used in these conditions.
