21FH Foundation Drill Rig
Precise, perpendicular mast positioning makes 21FH rigs well suited to serve as micropile drills.
Front-the-wall kinematics with seven joints provide versatile mast positioning, making 21FH rigs efficient as tieback drills.
Multiple bulkheads make troubleshooting and servicing hoses on the foundation drill rigeasier.
Less Downtime. More Drilling.
Foundation drillers who need equipment that can take the punishment of daily production choose the Geoprobe® 21FH Foundation Drill Rig. Engineered, manufactured, and supported in North America, the 21FH is built on field-proven Geoprobe® engineering trusted across geotechnical and geothermal drilling.
With a fully articulating drill mast, oscillating tracks, and a Eurodrill double head, the 21FH delivers the reliability and efficiency required for installing micropiles, tieback anchors, and soil nails day-after-day.
Key foundation drill rig advantages include:
- High-performance breakout system with 40-inch top clamp travel
- Next-generation kinematics with seven joints for versatile positioning
- Durable, predominantly mechanical controls for long-term reliability
Micropile Drills, Tieback Drills Designed to Simplify Service
Powered by a 275 hp CAT® engine, the 21FH foundation drill rig is engineered to reduce downtime and simplify troubleshooting in the field. Owners rely on continuous innovation and industry-leading customer support to maximize daily production and improve rig utilization.
Service Focused Design Features on Foundation Drill Rig:
- Plumbing routed around the engine compartment
- Multiple bulkheads for easier hose troubleshooting
- Breakout components replaced individually as they wear — no full breakout replacement
- Direct access to expert service technicians — a live person answers the phone
- Nationwide network of service centers
Drill Rig Telemetry
Use NEW drill rig telemetry to view live data from your machines. Monitor rig location, operating hours, fuel use, and error codes without leaving the office to stay ahead of maintenance and track performance, keeping every rig at its best.
Features & Options
Seven-joint, next-generation kinematics for drilling in tight environments means 21FH rigs are well suited as tieback drills.
Foundation drilling profits are realized when jobs stay on schedule. The 21FH is engineered to meet the production pace demanded of micropile drills or a tieback drill, incorporating features that make drilling — and servicing the rig — faster, easier, and safer.
Faster: The high-performance breakout system allows the top clamp to raise 40 inches above the bottom, improving efficiency during drilling operations. With no outriggers required, rig setup is faster and simpler, getting crews to work sooner.
Easier: Service-friendly design features include plumbing routed outside the engine compartment and multiple bulkheads that simplify hose troubleshooting. Durable, predominantly mechanical controls reduce complexity, and breakout components are designed to be replaced individually as they wear.
Safer: Next-generation kinematics with seven total joints provide versatile, precise positioning in confined or restricted environments. Oscillating tracks improve traction and stability on uneven or soft ground by distributing weight more evenly. An optional diverter directs fluids away from personnel and equipment for a cleaner, safer jobsite.
With drill rig service shops in North Carolina, Pennsylvania, Florida, and Kansas, expert support is always within reach for routine maintenance or in-depth repairs. Geoprobe® service technicians are available by phone during business hours and backed by our engineering team to deliver real solutions not band-aids. Most service parts ship the same day, and every rig is built and tested to ensure long-term reliability and easier serviceability.

Front the Wall Kinematics
Work in restricted spaces with fully articulating drill mast suited to serve as tieback drills.
Seven-joint, next-generation kinematics enable effective tieback installation while maintaining control in tight or restricted environments.
Eurodrill Double Head with Diverter Option
Efficiently complete foundation drilling with the Eurodrill double head.
Ideal for challenging soils or sensitive environments, the double head combines continuous flight auger drilling with simultaneous casing advancement. Optional diverter directs fluids away from the operator and rig to maintain a safer, cleaner jobsite.
Control Panel
Swing-arm control panel with built-in safety features and diagnostic tools.
Predominantly mechanical controls are intuitively arranged on the swing-arm control panel for ease of use and serviceability.
Breakout
Improving efficiency while breaking out, the top clamp raises 40 inches above the bottom clamp.
High-performance breakout allows 40-inch top clamp travel. Components are replaceable individually as they wear.
Oscillating Tracks
Tilt forward or backward with oscillating tracks for better stability and traction.
Improve ground contact, traction, and stability while reducing ground compaction on uneven terrain.
Head Side Shift and Winch Options
Head side shift allows drillers to reposition over the hole without moving the mast or machine.
Optional 5,000 lb winch available to pair with head side shift.
