Sandvik updates HLX5 rock drill for underground drilling

Sandvik Mining and Rock Technology has launched a new rock drill for underground rigs that, it says, offers improved energy efficiency and increased durability.

The RDX5 rock drill replaces the HLX5 rock drill model in Sandvik drilling equipment, which has a heritage and longstanding reputation for being the world’s most reliable rock drill, according to Sandvik.

The new RDX5 rock drill has a significantly increased minimum service interval than the previous HLX5 model, yet its design follows that of the HLX5, with a minimal number of moving parts and pressurised seams.

Innovations have been made to several components, Sandvik said. This includes the flushing head, gear housing and body cylinder; all of which delivers a new level of durability for internal items. The RDX5 also has a new percussion package and patented piston design to help improve energy efficiency.

“Designed for face and long hole drilling, as well as rock bolting, the new RDX5 rock drill is completely interchangeable with HLX5 rock drills in all applications where used,” the company said.
