Product Description

Reverse circulation hammers

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.
