Tundo™ RH650 DTH hammer from Sandvik cuts fuel consumption, improves penetration rate

The new Tundo™ RH650 hammer, the latest breakthrough development within down-the-hole (DTH) drilling from Sandvik Mining and Rock Solutions, can reduce fuel consumption by up to 15 percent while increasing penetration rates by up to 20 percent.

On display at MINExpo INTERNATIONAL® 2021 in Las Vegas, the Tundo™ RH650 6-inch DTH hammer is developed to increase sustainability and productivity. The hammer’s design features a new and highly efficient air cycle, contains no foot valve and is smaller and lighter compared to other hammers in its class. Flushing is done through the splines. An efficient air cycle means that the new hammer can be used on smaller class drill rigs, delivering fuel savings and efficiency benefits.

“With the revolutionary new Tundo™ RH650 DTH hammer, customers can drill more with less,” said Edgar Halling, Product Manager DTH Hammers at Sandvik Mining and Rock Solutions. Since it can be used on smaller class drill rigs - something unique in the market - customers can expect great cost savings, reduced investment costs, productivity improvements and reduced CO2 emissions.”

For a customer using a 6-inch DTH rig with a conventional hammer, the transition to Tundo™ RH650 could increase annual drilling productivity by 32,000 meters. Customers choosing to use a 5-inch rig would enjoy significant investment cost savings and reduce fuel consumption by up to 71,000 liters per year while reducing CO2 emissions by about 185 metric tons.

“In all our product development, which we do close to our customers, we aim to increase productivity and sustainability,” Halling said. “With this new hammer, we can not only help our customers on their journey towards more sustainable mining, we can also improve their bottom line in the process.”

The Tundo™ RH650 DTH hammer is available for order today with drill bit diameters of 6 ½ and 6 ¾ inches.
