Conventional down-the-hole drills can be equipped with modular diesel-powered units, making it easier to move the diesel engine from one site to another. The electric motor operation is more energy-efficient and environmentally friendly. When paired with a low-profile thruster, these drills can handle drilling operations in low-ceiling and confined spaces.

Optional configuration

Bidirectional shock-absorbing power head	New dust-collecting hood	Wide scope of work
A flexible connection is used between the power head and the drill rod, effectively isolating the impact of the hammer and rotational vibrations from being transmitted to the drilling rig, thus enhancing operational reliability.	The new structural features, such as the two-stage sealing design and the elastic casing that presses against the ground, effectively prevent rock debris from being ejected toward the drilling rig, making operations safer.
