The rotary auger bored piling is the foundation solution using a conventional kelly bar and auger system. Connecting the Kelly bar by Kelly box, the rotary auger can drill into soft soil, stiff clays or rock layers. According to the soil condition, the auger can be equipped with different kinds of teeth such as rock teeth B47K, soil teeth 25T, hard clay teeth BFZ72 etc. The length, the diameter and the shape of rotary auger can be customized to meet the requirements in projects. Generally speaking, the tapered auger can drill faster and the flat auger can help to take more soil out. For some MIDI drilling or limited drilling, the short tapered auger with C31 teeth is suitable due to the faster drilling speed.
