If you need a small borehole drilling machine that combines portability with real drilling power for rural water supply, farm irrigation, or domestic wells, the YG blue series is your answer. This compact, lightweight rig (only 200kg) drills up to 200m deep, with hole diameters from 100mm to 280mm, powered by a 22 HP or 30 HP diesel engine. The working process is simple: level the rig, select the bit, rotary drill with mud circulation to lift cuttings and stabilize the hole, add rods as needed, then extract and install casing. Key advantages include 50% higher single-hole efficiency than traditional small equipment, 30-minute on-site deployment via pickup truck, adaptability to soil, sand, and weathered rock, plus one‑button start and hydraulic feed that allows an ordinary operator to work independently after just 1-2 hours of training. Whether for water wells, geothermal loops, exploration, or monitoring holes, this portable water well drilling rig delivers reliable performance at a fraction of the cost and complexity of industrial drills.
What Is A Small-Borehole Drilling Machine?
It is a compact, portable rig designed to drill water wells, geotechnical exploration holes, and small-diameter boreholes with ease. Unlike traditional industrial drills that require flatbed trucks and extensive setup time, this equipment is built for mobility. Often referred to as a portable water well drilling rig or a compact drilling unit, it is engineered to navigate narrow farm gates, residential yards, and rugged terrains where larger equipment simply cannot go. For international buyers, especially those sourcing from overseas suppliers, understanding the balance between portability and drilling power is key. This equipment serves as the bridge between manual digging and expensive industrial drilling, offering a middle ground that emphasizes speed, fuel efficiency, and operator simplicity.

How Does A Compact Water Well Drilling Rig Work?
Understanding how a small-borehole drilling machine operates helps with troubleshooting and efficient use. The process begins with site preparation, where the rig is leveled using hydraulic stabilizers. Once set, the operator selects the appropriate drill bit and rod. For rotary drilling, the drill head rotates the bit while the hydraulic feed system applies downward pressure. Simultaneously, drilling mud (a mixture of water and bentonite) is pumped down the drill pipe, exiting through the bit. This fluid lifts the rock cuttings to the surface, where they settle in a mud pit, while also stabilizing the borehole walls to prevent collapse. As the hole deepens, additional drill rods are added. Once the target depth is reached—typically where water flows into the borehole—the rods are removed, and casing is installed. The entire process, depending on depth, can take anywhere from a few hours to two days.
Key Advantages Of This Portable Borehole Drilling Machine
YG’s small-borehole drilling machine stands out in the international market with four core advantages.
- High-Efficiency Drilling Performance: Equipped with a high-power, energy-efficient engine, providing strong output power. Drilling diameter ranges from 100 to 300mm, and drilling depth can reach 50-200 meters. Single-hole drilling efficiency is 50% higher than traditional small equipment, meeting the needs of batch drilling for small and medium-sized projects.
- Portable and Flexible Design: Lightweight and compact when folded, easily transported by pickup trucks and small vans. On-site deployment takes only 30 minutes, making it suitable for remote areas and complex terrain.
- Multi-Geological Adaptability: Equipped with wear-resistant drill bits in various specifications and an adjustable-speed power system, it can flexibly handle a range of geological conditions, including soil, sand, and weathered rock, and is suitable for shallow drilling.
- Convenient Operation: Features a one-button start and a hydraulic-assisted feeding design. The control panel is simple and easy to understand. Ordinary operators can operate independently after 1-2 hours of training, without requiring a professional technical background.
Versatile Applications Of A Lightweight Drill Rig
One of the standout features of this small-borehole drilling machine is its adaptability to different materials. It is not just for water wells. These rigs are highly effective for:
- Residential Water Wells: Drilling through clay, sand, gravel, and soft limestone.
- Geothermal Boreholes: Installing vertical loops for heating and cooling systems.
- Exploration Drilling: Taking core samples for mineral or soil analysis.
- Monitoring Wells: Installing piezometers for environmental studies.
