Product Description

Product Introduction:
The drill bit used is created out of tungsten steel which means that it is able to crush hard rock. The reverse circulation drilling machine is larger than most of the exploratory machines in the industry and that adds to the cost of running such a machine. The costs of using this procedure can be higher than the other techniques but the benefits of accurate, non-contaminated samples and being able to get samples from greater depths than most of the other drilling machines are capable of reaching makes using reverse circulation drilling worth the costs.
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.
