Product Introduce:
R.C. Drilling,referred to as "Center Sample Recovery" or "Dual Wall Drilling", employs a Dual Wall Pipe where the drilling medium, normally high pressure air,is passed between the outer and inner tubes down to the face of the drilling bit where it is returned up the centre tube along with the sample cut by the drill bit.

Adavantages:
1.No contamination
The R.C. System collects sample through the recovery holes in the face of the drill bit immediately as the cuttings or sample is formed.The drilled sample does not have to travel the length of the hammer where contamination and loss of sample takes place.
2.Higher Production
In broken and fractured ground conditions, the R.C. will often out perform the conventional hammer in terms of penetration rates.
3.Dry Sample
Even in certain water bearing stratas it is still possible to collect a dry sample because the cuttings(sample) are collected as they formed through the face of the drill bit.
4.Higher Sample Recovery
Because the sample is collected through the face of the drill bit there is no loss of sample when drilling through broken or fractured ground. And since the bit matched to the chuck size,there is very little bypass of sample and recovery rates of up to 98% are generally achievable.

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:
