4.5" Reverse Circulation RC Hammer with Remet and Metzke Thread for Sampling
Product Introduce:
Reverse circulation is achieved by blowing air down the annulus of the rod, the differential pressure creating air lift of the water and cuttings up the inner tube which is inside each rod. It reaches the deflector box at the top of the drill string then moves through a sample hose which is attached to the top of the cyclone.

Adavantages:
1. Reduced risk of cross-contamination. As the cuttings travel
through the drill bit’s inner tube and aren’t introduced to other
areas of the drill hole, the samples remain uncontaminated.
2. Faster and more efficient, reducing costs and providing greater
returns. RC drilling achieves higher production rates and can
achieve up to 200/300 metres per day. This means that results can
be delivered to clients faster, as the drilling itself takes less
time. The speed and efficiency involved also reduces manhours on
the drill rig, meaning savings on overall staff hours. Thanks to
the power and efficiency of the equipment, RC drilling is more
resilient in harsh environments, which makes it a cheaper option
overall. In fact, RC drilling has been shown to reduce costs by
25-40%.

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.
