Surface DTH drill rigs

Sandvik surface DTH drill rigs, equipped with powerful down-the-hole hammers, are designed for high-capacity rock drilling in surface mines. They are completely self-contained, with onboard compressors and efficient dust suppression. They are highly productive and very reliable, with low life-cycle costs.
High mobility DTH crawler drill rigs The Sandvik DI550 is representative of a new generation of Sandvik down-the-hole drill rigs for mines and contractors needing easy mobility. It matches perfectly with 5" hammers, making the rig uniquely productive and keeping fuel consumption and operating costs as low as possible.
