RC Drilling Reverse Circulation Down The Hole Bit 121mm For Exploration RE004
RC Drilling Reverse Circulation Down The Hole Bit 121mm for Exploration RE004
Product Introduce:
TReverse circulation drilling, or RC drilling, is a form of percussion drilling that uses compressed air to flush material cuttings out of the drill hole in a safe and efficient manner.
Thanks to the benefits enjoyed by this method, it’s become a popular technique in mining exploration and is one of the most common drilling methods across Australia and South America.
Adavantages:
2. Indirect cost reductions gained from a simplified sampling process
3. the samples are collected at the drill and sent directly to the lab to be assessed
4. less handling results in cost reduction and faster turnaround times
6. Requires less water than diamond drilling

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
