Atlas Copco Halco Reverse Circulation Hammer and Reverse
Circulation Bits
REVERSE CIRCULATION HAMMERS AND BITS
Roschen Reverse Circulation Hammer quality can be replaced of by Boart Longyear
, atlas copco basis on the quality grade, and in the after sales
service.
Reverse Circulation RC drilling uses flush-threaded double wall
drill pipe and high pressure air to provide continuous return of
formation and water samples. Cuttings and formation waters are not
contaminated with drilling additives or mixed with other borehole
material. Up-hole velocity of about 70 ft/sec provides reliable
logging of water, mineral or contaminant-bearing strata. Water
samples representative of specific strata may be airlifted or
bailed to the surface.
RC hammers are flexible and can be used in other drilling
operations such as:
- Water Well
- Soil Investigation
- Construction
- Mine Development
RC drilling is over five times faster than core drilling,
particularly in hard rock and almost half the cost of traditional
core drilling. RC hammers are pneumatically driven by compressors
and the principal operation of a Reverse Circulation hammer and
bits is the same as a standard DTH hammer. RC hammers and bits
follow the high performance design associated with traditional DTH
equipment and return the highest quality uncontaminated sample.
