An HDD drill rig is a machine used to bore holes underground without digging up the surface. It is also called an underground horizontal boring machine or a horizontal directional drilling rig. The machine drills a pilot hole from one point to another. Then it reams the hole to a larger size. Pipes or cables can be pulled through the finished hole. This method is great for crossing roads, rivers, and buildings.
The YG Series offers five models: YG-160A, YG-180, YG-280, YG-320, and YG-320A. Each HDD drill rig is built for different jobs. You can find a directional drilling machine for sale in this series that fits your needs.

Understanding Key Specs of The Horizontal Directional Drilling Rig
The numbers in the table tell you how the HDD drill rig will perform. You need to match the machine to your ground conditions and pipe size.
Push and Pull Force
This is the muscle of the HDD drill rig. Push force sends the drill pipe into the ground. Pull force brings the reamer back through the hole. The YG-320 model can push and pull 320KN. This makes it a strong underground horizontal boring machine.
Powerhead Torque
Torque is the twisting force that turns the drill bit. The YG-280 provides 10000N.m of torque. The YG-320 gives you 12000N.m. More torque is needed for rocky ground. It helps the horizontal directional drilling rig make steady progress.
Speed and Travel
The powerhead moves at a speed of 20 to 30 meters per minute. The YG-160A moves the fastest at 30m/min. Speed matters for job efficiency. A faster underground horizontal boring machine gets the job done sooner.
Drill Rod and Diameter
All models use a 3-meter drill rod. The rod diameter changes between models. The YG-160A uses Φ60mm rods. The YG-280 and YG-320 use Φ73mm rods. The rod angle is set between 10 to 23 degrees. This allows the directional drilling machine for sale to adjust to entry conditions.
Mudflow and Pressure
Mud is pumped down the hole at high pressure. It cools the bit and carries dirt back up. The YG series has mudflow from 160 to 320 L/min. The YG-160A operates at 100 bar. The other models run at 80 bar. Good mudflow makes the HDD drill rig work better in sandy or clay soils.

How to Pick The Right Underground Horizontal Boring Machine
Choosing the right HDD drill rig is important. A machine that is too small will struggle. A machine that is too big costs more money. Here are five points to consider:
- Ground Conditions: Hard rock needs high torque. The YG-320 series is better for rock. Clay and sand can use lower torque models.
- Pipe Diameter: Check the reaming capacity. Need a 750mm hole? Choose the YG-280. Need 800mm? Choose the YG-320.
- Bore Length: Long bores need high pullback force. The YG-180 offers 180KN. The YG-320 offers 320KN for longer bores.
- Engine Power: More power means faster drilling. But it also uses more fuel. Match the engine to your job needs.
- Weight and Transport: The YG-160A is easy to move. Heavier rigs need bigger trucks. Think about your job site access.
An HDD drill rig is an investment. Look at the specs carefully. The YG series has a model for every job. From 6700kg to 12500kg, there is an underground horizontal boring machine that fits your work.
