Product Description

Product Introduction:
Reverse circulation drilling (RC) is a drilling technique that allows samples to be retrieved with minimal contamination. The samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall.
Due to its high-quality sample results, and speed of operation for shallower holes, reverse circulation drilling is becoming increasingly popular around the globe. In fact, it's the most widely accepted chip sampling method.

Product Advantages:
1.High penetration rates in all rock conditions
2.Quality samples from areas of lost circulation
3.Large, uncontaminated sample return

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:
By Air, By express or By Sea
