PR54 High Pressure RC Drill Bit with Thread Metzke/Remet for Rock Drilling
Product Introduce:
The reverse circulation (RC) hammer is a simple non-electrical air motor that is driven by high-pressure air. An RC hammer exhausts the air down the outside splines of the percussion bit and then up its holes through the internal diameter of the hammer and the drill string to the surface
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.

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.
