The RC drilling machine, often referred to as a reverse circulation drilling rig, plays a crucial role in various fields like mineral exploration, infrastructure development, and water conservation projects. It adopts reverse circulation technology to collect stratum samples efficiently and accurately, which lays a solid foundation for project decision-making.
The core value of reverse circulation drill lies in its high efficiency, stability and strong adaptability. It can work stably in various complex terrains and strata, helping users reduce construction costs and shorten project cycles effectively. For global engineering teams, choosing a high-quality RC drilling machine is crucial to improving project benefits.

Key Performance Indicators of RC Drilling Machine: What to Focus On
Drilling Efficiency & Stratum Adaptability
Drilling efficiency is the primary indicator of a reverse circulation drill. A high-performance RC drilling machine can complete 200-300 meters of drilling per day in medium-hard strata, which is 2-3 times that of traditional drilling equipment. It can also adapt to different stratum conditions, from soft soil and gravel to hard rock.
For example, in hard rock mineral exploration, the tungsten steel drill bit of the YG RC drilling machine can easily break rocks with compressive strength up to 200MPa, ensuring continuous and stable drilling operations.
Transshipment Efficiency & Mobility
For field projects, the transshipment efficiency of reverse circulation drill directly affects the overall construction progress. YG integrated rc drilling machine with 6*6 off-road chassis can realize “drill immediately after arrival” without complicated disassembly and assembly.
Compared with split-type RC drilling machine, it can save 30% of transshipment time and reduce 40% of transportation costs, which is especially suitable for remote construction sites with inconvenient transportation.
Environmental Protection & Safety Performance
Modern construction projects have strict requirements on environmental protection. YG RC drilling machine is equipped with high-efficiency dust collectors, with a dust collection rate over 90%, which can meet the environmental protection standards of various countries such as the UAE, Canada and Australia.
In addition, it is equipped with a full hydraulic control system and multiple safety protection devices, which reduces the labor intensity of operators and ensures the safety of construction operations.
Global Success Cases of YG RC Drilling Machine
Case 1: Desert Power Tower Construction in the UAE
Client: Ahmed, a project manager of an infrastructure company in the UAE. His team faced problems of difficult transshipment and water scarcity in the desert power tower construction project.
Solution: YG provided an integrated RC drilling machine with 6*6 off-road chassis. This machine-integrated drilling rig, air compressor and chassis, realizes “drill immediately after arrival”. It adopted water-free drilling technology and a high-efficiency dust collector to adapt to the desert environment.
Results: The transshipment time was reduced by 4 hours per time, and the comprehensive cost was reduced by 35%. The daily drilling efficiency reached 220 meters, completing the 5,000-meter drilling project 10 days ahead of schedule. The dust collection rate reached 92%, fully meeting the UAE’s strict environmental protection standards.
Case 2: Gold Exploration in Canada
Client: David, a mining exploration engineer in Canada. He needed a RC drilling machine that could adapt to the cold and high-altitude environment in northern Canada and ensure the quality of gold ore samples.
Solution: YG customized a reverse circulation drill with low-temperature resistant components and an intelligent sample collection system. The reverse circulation drilling rig was equipped with a special heating device to ensure normal operation at -20℃.
