A new piston actuating mechanism performs with more percussion and generates more power at the same time, outperforming the FRD’s HD712 drifter.
FRD has developed the Dual-Damper System, a first in the industry. For maximum energy transfer, active DDS minimizes the return of shock waves by keeping the bit firmly against the rock at all times during drilling. It also minimizes percussion energy loss, and by optimizing the overall feed force, greatly improves the life of drilling accessories. An additional benefit is the greatly improved life of drilling accessories. Active DDS (U.S. Patent No. 5,896,937).
The drifter’s wedge type piston allows for greater impact efficiency.
The Furukawa HD800 Series drifter (patent applied for) is designed to minimize drill noise and vibration, while increasing performance.
With more impact, this drill has the ability to perform in harder rock at a larger diameter.
Stabilizes the bit against the rock, ensuring efficient energy transfer and straighter holes.
The Furukawa HD800 Series drifter (patent applied for) is designed to minimize drill noise and vibration, while increasing performance.
The ATD100 Air Track Drill is a self-propelled pneumatic crawler drill that can be used for both DTH and drifter drilling. It maintains a simple and lightweight design that is easy to operate and maintain.
