Compact HDD Rig for Utility Drilling

The UNI 12x20 horizontal directional drilling rig, manufactured by Universal HDD, is a compact and efficient solution designed for utility drilling, fiber optic installation, and trenchless construction in urban environments. It delivers reliable performance with balanced torque and optimized mud flow, making it well-suited for contractors working on residential and municipal infrastructure projects.

The UNI 12x20 is commonly used for underground utility installation, including water lines, gas pipelines, electrical conduit, and communication networks. Its compact footprint allows for easy transport and operation in confined job sites where larger rigs are not practical.

Compared to typical compact HDD rigs, the UNI 12x20 offers increased mud flow capacity, supporting improved borehole cleaning and enhanced drilling stability across varying soil conditions. This helps reduce downtime and ensures consistent performance during daily operations.

Compact directional drills like the UNI 12x20 play a key role in modern trenchless technology, enabling efficient project completion while minimizing surface disruption. The machine is compatible with standard HDD tooling and drill pipe systems, allowing seamless integration into existing contractor workflows across the USA.
