Our RC Drill Rig is a powerful drilling machine designed for fast and clean sampling. It works with a special reverse circulation system. The drilling principle is simple but effective. A dual-wall drill pipe sends compressed air down the outer pipe. The air pushes the cuttings back through the inner pipe and brings samples directly to the surface.
Unlike DTH drilling, reverse circulation does not require drilling mud. It reduces pollution and increases sample purity. This is why the RC Drill Rig is widely used in professional mining exploration.
Core Features Of YG RC Drilling Machine
Our RC drilling machine is designed to perform well in tough outdoor environments. It has several strong features that help users finish drilling tasks faster and more safely.
Key features include:
A high-power engine paired with a strong hydraulic system
Dual-wall drill pipes that support fast reverse circulation
High penetration rate even in hard rock formations
Clean sample recovery with low contamination
A heavy-duty chassis that works well in rough field conditions
Easy maintenance design with standard parts for quick replacement
These features allow the machine to keep a stable speed and sample quality even during long working hours.

Advantages Compared With DTH Drilling
RC drilling technology offers several clear advantages over traditional DTH drilling. Many mining companies choose RC because it improves sample reliability and reduces project cost.
Main advantages include:
Faster sample return speed, even in deep holes
Higher sample purity for accurate mineral evaluation
Lower operating cost due to stable and efficient air use
A stronger drilling system that ensures a long working life
Suitable for mining exploration, water projects, and geotechnical drilling
These strengths make the RC Drill Rig a valuable tool for professional drilling teams.
Application Scenarios Of A Reverse Circulation Drilling Rig
Users choose a reverse circulation drilling rig when they need accurate, fast, and clean samples from different depths. Some common situations include:
Mineral exploration that requires quick and precise rock samples
Geological mapping in hard or mixed rock layers
Mining companies that need high-quality samples for lab analysis
Construction projects that require deep drilling with strong stability
Projects that want to control costs by reducing air use and contamination
These needs show why RC drilling is now a preferred method for modern exploration projects.
