The new rotary drilling tool developed by SIP&T represents an innovation in the field of large vertical piling. It is a new generation auger, completely re-designed and manufactured in order to offer higher drilling performance in very hard rock strata. Designed to handle the most difficult drilling conditions, this auger is the evolution of years of drilling experience; it has been studied to work in very hard rock strata having a Compressive Strength more than 100 MPa. The geometry of the chisels arrangement is optimized for reaching excellent cutting performance, the flights pitch has been specifically designed to get better output characteristics for the high torque drilling rigs in order to improve material handling.
