A water borehole drilling machine is defined by its purpose: to reach underground water sources efficiently and reliably. But not all drilling rigs are built the same. Some are specialized for core sampling, others for water wells. The YG series water well drilling rig machine, does both. Our machine uses a vertical spindle design that delivers the controlled rotation and feed needed for core sampling, while also providing the torque and power required for water well drilling. It is a multi-application drilling system, not a single-purpose rig.
The YG series offers six models covering drilling depths from 180 to 600 meters and hole diameters from 140 to 350mm. Every model features a vertical spindle drive, crawler mobility, and flexible drilling modes. For contractors looking for a water well drilling rig machine that handles both exploration and production drilling, the YG series delivers proven performance across diverse applications.

Key Features of Water Borehole Drilling Machine
1. Multi-Terrain Adaptive Design with Dual Chassis Options
This rig is available with either a crawler or wheel-mounted chassis to match different site conditions. The crawler water well drilling rig features low ground pressure, so it avoids sinking in muddy ground and mountainous terrain. The wheel-mounted model is ideal for plain areas and road-based operations, with a maximum travel speed of 15 km/h for fast, efficient site relocation.
2. Intelligent Real-Time Pressure Monitoring System
The control console displays drilling pressure, impact air pressure and engine speed continuously during operation. It triggers an automatic alarm instantly when drilling pressure exceeds the safety limit. This function prevents drill pipe bending and equipment overload, effectively lowering on-site operational risks and reducing unexpected maintenance costs.
3. Versatile Depth Capacity for Shallow and Deep Wells
The water borehole drilling machine supports drilling depths ranging from 50 to 800 meters, covering both shallow domestic wells and medium-deep water supply projects. Its drill pipes adopt a quick-connect design with 1.5m single-section length, and each pipe replacement takes only 30 seconds. Operators can switch between shallow and deep well workflows without additional modification to the equipment.
4. Low Fuel Consumption & Energy-Efficient Operation
The 25hp model consumes only 3.5 liters of fuel per hour under full-load operation, delivering 20% higher energy efficiency compared with traditional drilling rigs. It only requires 35 liters of diesel for 10 hours of continuous running, which directly reduces daily operating costs and improves project profitability for drilling contractors.
5. Triple-Layer Emergency Shutdown Protection
The equipment is built with a triple automatic shutdown mechanism covering engine overheating, low oil pressure and pneumatic system overpressure. When a sudden fault occurs, it cuts off power supply within 0.5 seconds to protect core components and avoid permanent, costly damage to the rig.
6. Broad Compatibility with Drilling Tools & Strata
The water borehole drilling machine works seamlessly with alloy drill bits, diamond drill bits and auger drill bits, adapting to hard rock, soft soil, gravel and various other geological formations. One single unit satisfies drilling demands under different ground conditions, eliminating the need to invest in multiple specialized drilling devices.
How To Select The Right Water Borehole Drilling Machine?
Selecting a suitable rig starts with confirming your core project indicators. Many buyers overlook these details and end up choosing underpowered or oversized machinery. You should confirm four critical project factors before finalizing your order.
- First, clarify your primary application. Decide whether you need equipment mainly for geological core sampling or regular water well construction. Remember vertical shaft rigs complete both tasks, while full hydraulic core rigs only work for core extraction.
- Second, define target bore diameter and maximum drilling depth. These values decide which YG model fits your operation, as well as required drill pipe and drill bit specifications. A deep well drilling machine must provide enough lifting force and rotation torque to complete deep bore construction safely.
- Third, collect local geological information. Hard bedrock requires pneumatic drilling configurations. Sand, clay and loose rock layers need mud circulation drilling setups. Geological conditions also determine the proper drill bit material for long service life.
- Fourth, confirm transport and working environment demands. Teams working on hilly remote sites often prefer crawler chassis. Contractors frequently moving between urban project sites tend to pick trailer-mounted units. You also need to note special working conditions such as high altitude locations if applicable.
FAQs About Water Borehole Drilling Machine
A: Six models cover 180-600m depth and 140-350mm diameter. The specific combination depends on the model and the trade-off between depth and diameter.
A: Yes. The YG series vertical spindle design supports both applications. Full hydraulic rigs are typically limited to core sampling.
A: Pneumatic (air) drilling for hard rock and mud drilling for soft, unconsolidated formations. The operator switches modes based on the formation.
A: 76 mm, 89mm, 102mm, 108mm, and 114 mm, depending on the model. A larger pipe is required for deeper holes and larger diameters.
A: Under standard operating conditions with proper maintenance, the impactor can run stably for 2 to 3 years. Its actual service life will also be affected by rock hardness, daily working hours and regular lubrication maintenance.
A: The service life of the drill bit largely depends on the geological conditions on site. When drilling common rock formations, the drill bit generally lasts about half a year. Harder rock will accelerate wear and shorten its usable time.
