Reverse Circulation SRC543 Carbide Drill Bit With Black Color For Water Well Drilling
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. High drilling efficiency;
2. Timely sampling and high rate of adoption are conducive to accurately assessing the stratum;
3. Using higher grade carbides for longer life;
4. Minimizes hole erosion in fragile formations
5. Drills faster through soft formations with less blockages
6. Drills straighter through consolidated and unconsolidated formations

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.
