Buying a horizontal drill rig means matching the machine to your job. A machine that works for a 200-meter water pipe may fail for a 1000-meter gas line. Weight, engine power, hole diameter, and construction distance all matter.
Many buyers look only at the pullback force. That is a mistake. A heavy machine with high power but the wrong hole diameter will waste fuel. A light machine with a small size cannot complete long bores.
This guide gives you the full specifications for 14 hot-selling HDD drilling machine models. You will see weight, power, hole diameter, distance, and machine size. Use this data to pick the right machine for your next project.
The HDD rig machine you choose determines your daily operating cost. A properly sized machine saves $200 per day in fuel and wear.
We start with the full parameter table. Then we explain how to read each column. Finally, we give selection advice for different job types.

HDD Drilling Machine for Sale – Understanding the Specs
When you look at HDD drilling machine for sale listings, each specification tells a story. Here is how to read them.
Weight (kg)
The machine’s weight affects stability and transport. Heavier machines resist torque reaction better. They do not walk or shift during high-torque drilling.
- Under 5000 kg (YG130): Good for small utility work. One truck can transport it.
- 5000-10000 kg (YG200, YG250, YG320): Standard municipal jobs. Requires a trailer.
- 10000-20000 kg (YG360 to YG900): Heavy-duty jobs. Needs a low-bed truck.
- Over 20000 kg (YG12000T): Large pipeline projects. Needs special transport permits.
Engine Power (KW)
Power determines how fast you drill in hard ground. A 93 KW machine (YG130) works fine in clay and sand. But the same machine will struggle in limestone or granite.
For rock drilling, choose 150 KW or more. The YG320 has 154 KW. The YG900 has 239 KW.
Hole Diameter (MM)
This is the maximum hole size the directional drilling equipment can create. Match this to your pipe size plus 30% for mud space.
Example: A 500mm pipe needs at least a 650mm hole diameter. The YG130 (750mm hole) works. The YG200 (900mm hole) gives more safety margin.
Construction Distance (M)
This number assumes ideal ground – uniform clay with no rock. Reduce the distance by 30% for mixed ground. Reduce by 50% for hard rock.
A machine rated for 300 meters (YG200, YG250) can safely do 200 meters in fractured rock.
Machine Size (MM)
Length x width x height. This matters for site access. A machine 10 meters long (YG900) needs a long setup area. It cannot work in a small urban lot where space is tight.
2. HDD Rig Machine: Model by Model Analysis
This section helps you select the right HDD drilling machine for your specific needs.
YG130 – The Entry Level Choice
Weight: 4750 kg | Power: 93 KW | Hole: 750 mm | Distance: 200 m
The YG130 works for small contractors. Use it for:
- Fiber optic cable installation under local roads
- Water service connections to individual houses
- Short bores up to 150 meters in soft ground
Best ground: Clay, sand, loam. Avoid hard rock.
Transport advantage: Fits on a standard flatbed truck. No special permit needed.
YG200 and YG250 – The Municipal Workhorses
YG200: 8200 kg, 113 KW, 900 mm hole, 300 m distance
YG250: 9000 kg, 110 KW, 1000 mm hole, 300 m distance
These two models compete for the same jobs. Choose YG200 for a slightly better power-to-weight ratio. Choose YG250 for a larger hole diameter.
Use them for:
- Gas line installation under two-lane roads
- Water mains up to 400mm in diameter
- Sewer force mains
Both machines fit into a 20-foot shipping container. Good for export.
YG320 and YG360 – The Rock Drillers
YG320: 10500 kg, 154 KW, 1100 mm hole, 400 m distance
YG360: 9500/10500 kg, 153/154 KW, 1200 mm hole, 450 m distance
The extra power (154 KW vs 110 KW on YG250) makes these machines suitable for limestone and sandstone. They maintain torque even at 80 rpm.
Use them for:
- River crossings up to 400 meters
- Drilling through caliche or weathered rock
- Pipeline projects in hilly areas
The YG360 offers two weight options. The 10500 kg version adds steel plates for stability. Use it when drilling through fractured rock.
YG380 and YG420 – Long Distance Specialists
YG380: 12800/14270 kg, 179 KW, 1300 mm hole, 600 m distance
YG420: 13000 kg, 179 KW, 1350 mm hole, 650 m distance
These machines focus on length. They use a longer drill rod magazine. They also have larger mud tanks to maintain circulation over long distances.
Use them for:
- Crossings under multi-lane highways
- Pipeline installation under railways
- Bores through residential areas (minimizes disruption)
The HDD rig machine in this class can work 10 hours continuously. The cooling system handles the load.
YG450, YG450B, YG700L – High Volume Production
YG450B: 13500 kg, 194 KW, 1400 mm hole, 700 m distance
YG450: 14500 kg, 194 KW, 1500 mm hole, 800 m distance
YG700L: 15000 kg, 199 KW, 1500 mm hole, 900 m distance
These machines drill large diameter holes for big pipes. A 1500 mm hole can accept a 1000 mm water main. That supplies a small town.
Use them for:
- Regional water supply pipelines
- Large diameter sewer interceptors
- Power cable tunnels (multiple cables in one bore)
The YG700L adds 500 kg and 5 KW over the YG450. It also has a longer frame (9100 mm vs 8450 mm). The extra length stores more drill rods.
YG900 and YG900A – Heavy Duty Export Models
YG900: 15000 kg, 239 KW, 1500 mm hole, 1000 m distance
YG900A: 21000 kg, 264 KW, 1500 mm hole, 1000 m distance
These machines have the same hole diameter but very different power and weight. The YG900A adds 6000 kg and 25 KW. That extra weight helps when drilling through boulders or very hard granite.
Use them for:
- Mountain crossings with solid rock
- Long river crossings (1 km)
- International projects with unknown ground conditions
The YG900A has an oversized cooling system. It runs in a 45°C ambient temperature without overheating.
YG12000T – The Flagship
Weight: 81,000 kg | Power: 2×565 KW + 1×264 KW | Hole: 2000 mm | Distance: 3000 m
This is not a machine. It is a system. The YG12000T has three engines. Two provide 565 KW each for thrust and torque. One provides 264 KW for the mud system.
Use it for:
- Major oil and gas pipelines
- Long-distance water transfer projects
- Bores under mountains (3 km pulls)
The machine requires a crew of six. It needs a separate generator for site lighting. It consumes 150 liters of diesel per hour at full load.
Only buy this class for large national infrastructure projects.
3. How to Select the Right HDD Rig Machine Model
Use this decision flow.
Step 1 – Measure your pipe diameter.
- Pipe ≤ 500 mm → YG130 or YG200
- Pipe 500-800 mm → YG250 or YG320
- Pipe 800-1000 mm → YG380 or YG420
- Pipe 1000-1200 mm → YG450 or YG700L
- Pipe >1200 mm → YG900A or YG12000T
Step 2 – Measure your bore length.
Take the construction distance from the table. Multiply by 0.7 for mixed ground. Multiply by 0.5 for hard rock.
Example: YG320 rated for 400 meters. In mixed ground, plan for 280 meters maximum.
Step 3 – Check your site access.
Measure the road width to your site. Add 2 meters for the truck turning radius. Compare to the machine size.
YG900 is 10.6 meters long. It cannot enter a site with a tight 90-degree turn from a narrow street.
Step 4 – Add 30% safety margin to the hole diameter.
A 1000 mm pipe needs a 1300 mm hole. Choose YG380 or higher.
4. Directional Drilling Equipment – Key Features Across Models
All YG series directional drilling equipment shares these features:
- Hydraulic rod loader (except YG130 – manual loader)
- Automatic mud mixing system (standard on YG200 and above)
- Wireless steering display (color screen)
- Emergency stop at the operator station and remote
Optional extras:
- GPS tracking module
- Remote diagnostic system (sends error codes to the service center)
- Heated cab for cold climates
5. HDD Drilling Machine for Sale – What the Table Does Not Show
The parameter table gives hard numbers. But some important factors are missing.
Service intervals:
- YG130 to YG250: oil change every 250 hours
- YG320 to YG900: oil change every 500 hours (larger oil pan)
- YG12000T: oil change every 1000 hours with oil analysis
Fuel consumption at full load:
- YG130: 12 L/hour
- YG200/YG250: 18 L/hour
- YG320 to YG700L: 25-30 L/hour
- YG900/YG900A: 38 L/hour
- YG12000T: 150 L/hour
Common spare parts availability:
All models use standard hydraulic fittings (JIC 37 degree). Seals and filters come from major brands (Parker, Donaldson). No proprietary parts that force you to buy only from the factory.
6. HDD Boring Machine – Transport and Setup Tips
The HDD boring machine size affects your daily setup time.
YG130: Two people can unload it with ramps. Setup takes 30 minutes.
YG200 to YG450B: Needs a mobile crane or truck with a crane. Setup takes 90 minutes for an experienced crew.
YG700L to YG12000T: Needs a 50-ton crane. Setup takes 4 hours. Requires a concrete pad or heavy timber mats.
Site preparation for heavy models (over 15 tons):
- Level ground within 0.5 degrees
- Compacted gravel base at least 20 cm thick
- Drainage away from the machine (mud spills are slippery)
7. HDD Rig Machine Model Comparison: Which One Gives the Best Value?
For most contractors, the YG320 (10500 kg, 154 KW, 1100 mm hole, 400 m distance) offers the best balance.
Reasons:
- Enough power for limestone and clay
- Hole diameter covers 80% of municipal jobs
- Weight allows transport without overweight permits in most countries
- Price is 40% less than YG900
For purely soft ground work, the YG200 (8200 kg, 113 KW) is the most economical. It costs 30% less than YG320 and burns 30% less fuel.
For large pipeline contractors, the YG900A (21000 kg, 264 KW) is the best rock machine. It weighs enough to stay stable. It has the power to drill fast. And it is still small enough to ship in two containers.
The YG12000T is for national projects only. Most contractors will never need it. Rent it if you have one very long bore. Do not buy it.
8. Conclusion on HDD Boring Machine: Use the Table, But Verify on Site
The horizontal drill rig specification table gives you a starting point. But no table can replace a site visit.
Before buying any HDD rig machine, walk the bore path. Look for rock outcrops. Check the water table. Talk to local drillers. They know the hidden problems.
Then match the machine to the job – not the other way around.
