Down-The-Hole Drill
We adopt the new hydraulic technology to our down-the-hole drill, which features low air consumption, large rotary torque and compact structure. Besides, the holes of our DTH drill can be easily shifted. If advancing the carriage, you will find that our down-the-hole drill has the function of telescopic compensation.
While drilling, the drilling equipment will be supported by the carriage on the ground to have good stability. When doing the outdoor construction, the down-the-hole drill can tow the air compressor and facilitate the transition shift. Having flexibility and climbing ability, it is suitable for the operation in the rugged venue.
Our superior down-the-hole drill can be widely and excellently applied to ranges of fields, such as mining, road construction, building infrastructure, water and electricity projects, etc.
