Reverse Circulation DTH Hammer Pr54 with RC Bit for Rock Drilling / Mining
Product Introduce:
Reverse Circulation drilling, or RC drilling, is a method of drilling which uses dual wall drill rods that consist of an outer drill rod with an inner tube. These hollow inner tubes allow the drill cuttings to be transported back to the surface in a continuous, steady flow.
The drilling mechanism is a pneumatic reciprocating piston known as a hammer driving a tungsten-steel drill bit.

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
