UNI 12x20 Compact HDD Rig for Utility Drilling

The UNI 12x20 is a compact horizontal directional drilling rig built for utility contractors who need reliable performance in tight urban and confined jobsite conditions. With 12,000 lbs of thrust and pullback and 2,000 ft-lb of spindle torque, this small directional boring machine delivers consistent results across a wide range of ground conditions — from sandy soils to mixed formations.

The UNI 12x20 is purpose-built for fiber optic installation, telecom last-mile buildout, water service lines, gas distribution, and electric conduit — applications where a full-size horizontal boring machine can't access the site. Its compact footprint of 158" × 53" and 9,700 lb operating weight make it easy to transport and set up in road medians, parking lots, and residential corridors without disrupting surrounding infrastructure.

Powered by a 74 HP turbo diesel engine with a 30 gpm mud pump, the UNI 12x20 supports efficient borehole cleaning and stable drilling fluid delivery on every bore. Standard features include Cruise Control System, integrated Mud Flow Indicator, Wired Remote Control, Stake-Down anchoring, and an Integrated Diagnostic System for real-time field troubleshooting — reducing downtime and keeping crews productive on demanding jobsites.

Compatible with standard HDD drill pipe and tooling systems, the UNI 12x20 integrates seamlessly into existing contractor workflows. Drill rod options include 1.66" and 1.90" Firestick configurations — 60 rods standard.

The UNI 12x20 is manufactured in Lake Zurich, IL, USA by Universal HDD — sold factory-direct with no dealer markup. Lead time 3–4 weeks. Full service support and worldwide delivery available. Request a quote today at (847) 955-0050.
