Product Description
High Air Pressure RC Reverse Circulation Hammer SRC547
Product Overview
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.

Key Features
- Versatile across terrains: Compared with diamond drilling, Reverse Circulation drilling uses far less water, making it ideal for remote areas where water sourcing can be challenging. With approximately 40% lower operational costs, it's a reliable choice for complex and remote locations.
- Reliable samples: The RC drilling method keeps samples free of cross-contamination as cuttings travel through the inner tube without exposure to other areas of the hole. Samples are precisely labeled by depth and location.
- Workforce and time savings: Cover more ground in a day with rapid retrieval of drill cuttings and superior production rates compared to diamond core drilling. The small rig footprint eliminates the need for extensive earthworks.
