Dual-Damper System DDS
FRD has developed Dual-Damper System, a first in the industry.For maximum energy transfer, active DDS minimizes return of shock waves by keeping the bit firmly againts the rock at all times during drilling.Active DDS minimizes percussion energy loss and,by optimizing the overall feed force, reduce hole deviation.An additional benefit is greatly improved life of drilling accessories.

Compact Valve Design
A compact shuttle valve minimizes loss of oil pressure and maintains total power output of the drifter.
