Instructions
The YONDA YDH2004J Hydraulic Drifter is engineered for anchor drilling, micropile drilling and foundation applications. Its integrated design combines hydraulic percussion with dual-motor rotation, while two selectable rotary modes allow the system to switch between higher drilling speed and higher torque according to ground conditions.
The integrated flushing system supports efficient cuttings removal, while hydraulic reverse percussion assists with releasing and retrieving drilling tools when difficult ground conditions are encountered. The YDH2004J can be configured with male-threaded shank adapters for R70, GT60, T38, T45, T51, R38, R32 and H64 drilling tools. It is suitable for drilling in rock, gravel and cobble formations for anchoring, geological exploration, micropiles, foundation reinforcement, slope stabilization and tunnel pipe-roofing works.

FAQ
1. Can the YDH2004J drill through gravel and cobble formations?
Yes. Its integrated percussion-and-rotation design allows it to work in general rock as well as gravel and cobble formations. Final suitability should be evaluated according to the required hole diameter, drilling depth, drilling tools and ground conditions.
2. What is the purpose of hydraulic reverse percussion?
Hydraulic reverse percussion assists with releasing and retrieving drilling tools when they become stuck or difficult to withdraw, reducing the difficulty of tool recovery in challenging formations.
3. Does the YDH2004J include a flushing system?
Yes. The YDH2004J features an integrated flushing system to support cuttings removal during drilling. The flushing medium and supply conditions should be confirmed according to the drilling tools and application.
4. What information is required to confirm compatibility with an existing drill rig?
Please provide the drill rig model, hydraulic pressure and flow, mounting dimensions, required hole diameter and depth, ground conditions and drilling-tool thread. YONDA can then evaluate the suitable configuration.
