Down the hole rock tools (drilling tools) are rock drilling
equipment which takes compressed air as power source to partially
transfer impact power into drilling holes. An air distributing
device in a top hammer controls a piston to move back and forth. An
impact device arranged in the front of the top hammer transfers the
impact powderto a down-the-hole bit to crush rocks.
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
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
5. In difficult conditions such as loose soil, hard rock and plenty
of water exists, sampling can be done well.
Our DTH hammer are widely applied to open pit and underground
mining to drill blasting holes, drainage holes, ventilation holes,
center holes or blasting holes of raising boring, pipe holes and
other deep holesin all various strength rocks, such as quarry
exploitation, earthwork projects, water-well, constructionsand so
