High Air Pressure 5.5inch Reverse Circulation Down The Hole Hammer with 124.5mm Diameter and RE547 Shank

Reverse circulation drilling (RC) is a drilling technique that allows samples to be retrieved with minimal contamination. Drilling is typically done using a down-the-hole, tricone, or triblade bit. The samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall. This quick execution technique is usually performed within a diameter of 150 mm and depths ranging between 50 and 200 meters.
