wells and ore mining, etc. And it's specifically designed to work
with RC Hammers.
Application
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 different conditions such as loose soil, hard rock and plenty
of water exists, sampling can be done well.

1) Face design: flat, convex, concave
2) Inserts design: spherical, ballistic, parabolic
3) Typical bit model: RE545, RE547
4) Bit diameter: 90mm to 213mm
5) Reliable quality
6) Long service life
7) Smooth flushing effect
8) Designed to work with RC hammers
