Audited Supplier 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.

1.High drilling penetration rates:
RC penetration rates are comparable to open drilling methods and are often faster at greater depths. Sample velocity through the inner tube can reach speeds of 250 m/sec, making the retrieval of drill cuttings a rapid but safe method requiring fewer man-hours.
Production rates are superior to diamond drilling; rates of 200-300 m/day are routine at speeds faster than 10 m/h. Therefore, results from RC drilling can be revealed to clients much faster because the drilling process takes less time.
2.Versatile in tough conditions:
RC drilling is fairly straightforward and requires far less water than diamond drilling, making it ideal in places, where water may be scarce or costly. RC drilling is also a more cost-effective method than diamond drilling, with operating costs reduced by up to 40% compared to diamond drilling.
Cost reduction is especially noticeable in geologically challenging locations, which would increase the cost of more conventional drilling methods even more. RC drilling will keep those costs down since it is more resilient in harsh environments.
