We are making a better
Quality and reliability are our main focus
The reverse circulation hammer (RC-DTH) is an innovative air-driven DTH percussion drilling tool. Unlike the conventional DTH hammer system, the specially designed structured bit is the key part of the RC-DTH hammer system, and the double-walled drilling pipes are designed for transporting both compressed air and drilling cuttings.
Our RC hammers use low working pressure to achieve high performance and energy efficiency, minimizing maintenance needs. With robust shanks ideal for heavy-duty tasks, our hammers have a non-reversible outer liner and specialized heat treatments to increase the lifespan of their wearing parts. These features ensure long-lasting and efficient operation with minimal maintenance requirements.
Unlike conventional DTH hammer systems, the drill pipes are double-walled designed to transport both compressed air and drilling cuttings.
During drilling, compressed air is injected into the annular space of the double-walled pipes and activates the RC DTH pneumatic hammer to generate high-frequency impacts that act on the RC bit, where reverse circulation is formed.
