High and versatile performance

There are a number of reasons why Wassara is faster than diamond core drilling and top hammer drilling for long holes. The system is much more efficient with a higher frequency compared to an air DTH hammer (3,600 blows per minute compared to 2,000-2,700 bpm with air DTH) and a costant percussive force. And since the hammer is always at the bottom of the hole, no impact power is lost through the drill string, therefore the penetration rate is maintained even at significant depths.
