Reverse circulation drilling (RC) is a drilling technique that allows samples to be retrieved with minimal contamination. Drilling is typically done using a down-the-hole, tricone, or triblade bit. The samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall. This quick execution technique is usually performed within a diameter of 150 mm and a depth that varies between 50 and 200 meters.
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.
Product Advantages:
1.Samples extracted are reliable and free of contaminants;
2.The method is timely and cost-efficient;
3.Well-suited for difficult terrains;
4.High penetration rates, and it has minimal environmental impact.

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.
