Description
Our Performance Shoe Driller ( PSD™ ) Bi-Center bit offers increased stability beyond the CSD bi-center design. By drilling backward while drilling out, the tool minimizes the length of time and volume of material removed while rotating backwards. It eliminates your need for a dedicated drill-out blade, resulting in superior ROP, improved hydraulic performance, and class-leading drill-out capability.
Features/Benefits
