RC series 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 recerse circulation hammer, optimized internal structure and ideal energy transfer, thus ensuring the series of hammers deilling 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 intergrative 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 condition such as loose soil, hard rock and plenty of water exists, sampling can be done well.
