product of our company. It is mainly used for deep exploration
drilling and core sampling.
It has the following characteristics:

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
