Deep Exploration Drilling

 

RC series reverse circulation DTH hammer is the latest developed product of our company. It is mainly used for deep exploration drilling and core sampling.

Reverse Circulation RC DTH Drill Bit

RCseries reverse circulation DTH Hammer is the latest developed product of our company. It is mainly used for deep exploration drilling and ore grade control.

 

 

It has the following characteristics:

1.Based on previous experience of ordinary hammers, combined with the features of reverse circulation hammer, optimized internal structure and ideal energy transfer, thus ensuring the series of hammers drilling with fast, smooth and continuous sampling.

 

2. The internal structure is very simple with components of high rigidity, thus ensuring long life and easy maintenance of the hammer.

 

3.The collection tube adopts an integrative design and can be replaced without disassembling the hammer. With carburizing treatment, it has good abrasive resistance.

 

4.Equipped with bits designed with patent. Simply by replacing the drill bit, the same hammer can drill holes of different sizes ensuring that the sample is not contaminated.

 

5. In difficult conditions such as loose soil, hard rock and plenty of water exists, sampling can be done well.
