Drilling machines serve as foundational engineering equipment for subsurface operations, delivering precise boreholes across soil, sand, weathered rock and hard granite. YG Machinery supplies a full‑series lineup of drilling machines, covering mineral exploration, mine blasting, trenchless pipeline installation, foundation piling, water well construction and geotechnical investigation. Built with high‑grade steel and premium hydraulic components, our rigs adapt to mountainous, swampy and high‑altitude sites, cutting downtime and lowering overall project operating costs.
Core Drilling Machine for Mining
Designed for mineral exploration and geological survey, YGX‑series core drilling machines adopt diamond‑tipped bits to retrieve intact cylindrical rock core samples. Models range from YGX‑400 to YGX‑1000, supporting drilling depths from 180 m up to 1100 m. Equipped with Yuchai or Cummins diesel engines and dual air‑water cooling systems, these rigs deliver adjustable spindle speed, strong lifting and feed force, achieving excellent core recovery for accurate mineral reserve assessment. They are widely deployed for metal‑nonmetal mine exploration, dam foundation investigation, hydrological survey and environmental stratum evaluation.

DTH Drilling Rig
Down‑the‑hole drilling rigs feature a hammer placed inside the borehole, transferring impact energy directly onto rock with minimal energy loss. YGS‑series crawler DTH rigs drill holes of 83‑165 mm diameter, excelling at hard rock blasting holes for open‑pit mines and quarries. Reinforced crawler chassis guarantees stability on rugged slopes, while carousel‑style rod changers shorten auxiliary operation time. Besides mining blasting, they handle water well drilling, foundation anchor holes and slope stabilization works, offering reliable hole straightness for safer and more efficient blasting operations.
HDD Drill Rig
) As trenchless construction equipment, YG HDD drill rigs complete pilot bore, hole reaming and pipe pull‑back without surface excavation. The product range includes YG‑160A, YG‑180, YG‑280, YG‑320 and YG‑320A. With maximum pull‑force up to 320 KN and peak torque of 12000 N·m, they can ream holes up to 800 mm. Ideal for crossing roads, rivers and buildings, these rigs install fiber‑optic cables, power lines, water‑sewage pipelines and oil‑gas pipes, minimizing ground damage for urban infrastructure projects.
Rotary Drilling Machine
Rotary drilling machines rely on high‑torque rotary heads and drilling buckets to excavate soil and rock for foundation construction. Suited for building pile foundations, bridge piers, highway and municipal projects, they complete large‑diameter deep boreholes efficiently. Adjustable drilling angles and robust structural design enable stable performance in mixed geological layers, becoming essential equipment for high‑rise building and large‑scale infrastructure piling jobs.
Small Well Drilling Rig
Compact and lightweight small well drilling rigs target rural water supply, agricultural irrigation wells and geothermal boreholes. Some portable models can be fully disassembled for easy transport by pickup trucks. Featuring simple operation, low fuel consumption and short setup time, they work in soil, sand and weathered rock formations, delivering cost‑effective solutions for small‑scale water‑well and monitoring‑well projects in remote areas.
All YG drilling machines support OEM and personalized customization, covering winter‑proof packages, power configuration and emission‑standard adjustment. We provide 12‑month warranty for main components, remote video technical guidance, operator training and global spare‑parts supply. Whether for large‑scale mining projects or small‑capacity on‑site tasks, YG can match proper drilling equipment for your working conditions.
