4.5'' Reverse Circulation RC Drill Bit With Shank SRC542/543 For Mining
Product Introduce:
Reverse Circulation drilling, or RC drilling, is a method of
drilling which uses dual wall drill rods that consist of an outer
drill rod with an inner tube. These hollow inner tubes allow the
drill cuttings to be transported back to the surface in a
continuous, steady flow.
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.

Working principle
The on-board compressor delivers power to a pneumatic reciprocating
piston. The piston, in turn, drives a tungsten-steel drill bit
which is purpose designed to be able to crush hard rock.
Similar to air core drilling, drill cuttings are returned to
surface inside rods. We achieve this through the use of dual wall
drill rods: an outer drill rod with an inner tube. When compressed
air is blown through the rod, the volume displaces the air, lifting
the samples to the surface.
Once cuttings reach a diverter at the top of the hole, they’re
moved through a hose and around the cyclone, which slows the sample
down. From the cyclone the sample goes over a splitter that
delivers a percentage of the entire sample into a sample bag. The
exploration drilling team then collect the samples aligned to the
hole depth and lay them out for the client to log, and then
transport to the lab for assay.

About us:
SOLLROC Reverse Circulation drilling (RC) ,from size 3’’ to 5.5’’, 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.
