"Our new Sandvik UNIFACE down-the-hole drill bits deliver the longer life essential for cutting costs and improving productivity. In fact, Sandvik UNIFACE bits last up to 80% longer than current Sandvik DTH bits!
The new bits are designed for optimized flushing that gives a more even wear of the gauge, increasing bit life. In order to achieve a consistent penetration rate, the buttons have been placed so that they always hit fresh rock.
