Dual Wall Drilling 3" And 3.5" Remet 3.5 RC Hammer Collect Dry
Sample
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 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.
