Product description
Revirse circulation drilling is a technique of drilling that uses
dual wall drill rods that consist of an outer drill rod with an
inner tube. By using compressed air to extract rock fragments
sample,the samples travel through rods to a sample splitter at
surface, avoiding all contact between the samples and the borehole
wall that allows samples to be retrieved with minimal
contamination,which is mainly used in deep hole exploration and
mining grade control.

Applications
RC hammers and bits are used in hole drilling in mines, hydrology
and water well, geothermal well, geothermal air conditioning well,
geologic exploration, complicated gravel stratum, etc. Especial suitable for complicated formation (Formation loose,
difficult to drilling and unstable of hole wall), exhausting for
deep hole, environment protection.
Reverse circulation (RC) drilling uses a bit attached to a
down-hole hammer to produce a hole. Unlike diamond drilling, RC
drilling produces samples of rock cuttings rather than a sample of
rock core. The down-hole hammer is powered by compressed air, which
also acts as the medium bringing the drill cuttings up to surface.
It is mainly used in deep hole exploration and mining ore grade
control.
