Product Introduce:
The Reverse Circulation drilling (RC drilling) method involves air being forced down between the inner and outer pipes of a dual wall drill pipe with the cuttings being forced up through the centre of the drill rods. This is the opposite of conventional DTH hammer drilling which instead sends the air flush through the centre of the drill string, with the cuttings being forced up the hole outside the hammer and drill rods.
The benefits of reverse circulation drilling are well documented. Samples are protected from cross-contamination since they are pulled up in sequence as the reverse circulation drill bit cuts new rock. Reverse circulation drilling consumes less water than other drilling techniques, such as diamond drilling.

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.
Delivery Way:
