Dual-Damper System DDS
FRD Has developed Dual-Damper System 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.
(U.S.PATENT No.5,896,937)

Compact Valve Design
THE FURUKAWA HD700 series drifter is designed to minimize drill noise and vibration without sacrificing performance.Incorporating a new piston design, the HD700 drifter maximizes energy transmission and drills effectively in a variety of rock types.
