High Performance SRC543 Reverse Circulation Hammer 4.5inch 116mm for 121-146mm Hole Range

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 a depth that varies between 50 and 200 meters.

• Versatile across terrains: When compared with diamond drilling, Reverse Circulation drilling uses far less water, making it ideal for remote areas of WA, where sourcing water can drive up the running costs of an operation. Compound this with an average 40% lower operational cost, and it's a reliable choice for complex and remote locations.
• Reliable samples: One benefit of RC drilling is in keeping samples free of cross-contamination. Because the cuttings travel through the inner tube, they aren't exposed to other areas of the hole. Furthermore, samples are labelled relating to depth and location.
• Workforce and time savings: Cover more ground in a day. Combining a rapid method of retrieval of drill cuttings and superior production rates than diamond core drilling, means you get results from RC drilling faster. RC drilling also has a small rig footprint, eliminating the need for extensive earthworks.
