Shroud Dia 93mm RC Series 3'' RC Bit 95mm With 14 Buttons Shank SRC531 For RC Hammers
Product Introduce:
The reverse circulation drilling method has the capability of reaching depths of 500 metres. A pneumatic hammer-like device is used to hammer into the earth to remove rock samples which are then pushed up into the mining machine using compressed air. The samples are collected in a sample bag which is located within the machine. More than one sample bag can be collected which allows for more of a variety of samples to be analysed. Sample bags are usually marked to show the location from which the sample was taken as well as the depth from which the samples are extracted.

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
7. When drilling in the aquifer, the blockage of the pore wall by the mud can be avoided, and the original natural permeability of the formation can be maintained.

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.
