Rotary Drilling Auger
Borsure rotary drilling rock augers are designed for fast and stable soil excavation in foundation drilling operations. According to different drilling requirements and ground conditions, our augers are mainly classified into Straight Flight Augers and Tapered Flight Augers, with multiple structural options to optimize drilling efficiency and spoil removal.
Straight Rock Auger
Straight rock augers are designed for general soil drilling. The constant flight diameter ensures smooth spoil lifting and stable drilling in clay, sand and loose soil formations.
