Reverse circulation drilling
REVERSE CIRCULATION PERFORMANCE TOOLING
Reverse Circulation (RC) drilling is used to collect rock samples
quickly and efficiently using a large rotary drill and air
compressor. The high speed and lower cost per meter of RC drilling
makes it ideal for obtaining mineral samples in the early phases of
an exploration project.
Features:
1. Optimization of inner structure offers faster drilling speed and
more stable operation.
2. Easy maintenance with simple inner structure and strong rigidity
3. With all-in-one collective tube, the RC hammer can be replaced
without disassembly.
4. With special design of bit, RC drilling for different sizes of
holes only by changing bit.
The components of reverse circulation DTH drilling tools:
1. RC drill bit
2. RC hammer
3. Double drilling pipe
