Description
The new diamond dart impactor uses the latest drilling theory to
design impactor, which enables the impactor to get the best energy
transfer, fast drilling speed and low air consumption. The best
quality of raw materials and the most advanced processing
technology, stable performance and long life. Easy to use, easy to
install and disassemble, easy to repair and easy to repair.
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.
Applications
Widely used in mines, quarries, earthworks and other engineering
drilling blasting hole, guardrail hole, mountain reinforcement,
anchorage and other engineering holes, geothermal exploration hole,
Well bore and other fields.
