Double head drilling units

The double head drilling units are assembled using high-performance INTEROC hydraulic drifters and rotary heads. They are designed for drilling with inner rod and outer casing in all common diameter ranges and ground conditions

Double head drilling units are powered by two axially-positioned drill heads. The lower drive consist of a rotary unit with a hollow shaft of sufficient diameter to accept an equalizer rod. The upper drive activates the inner drill string via the equalizer rod.
