Features of Wassara hammers

Differences with conventional DTH hammers:

• These hammers are more respectful of the land and environment
• They do not use oil for lubrication, which means there is no air or water pollution.
• The water used also effectively removes dust.
• This is the the most environmentally friendly percussion drilling method currently available.
• It also offers a significant energy savings compared to DTH air technology.
• This technology achieves high efficiency with greater penetration and straighter perforations.
• The incompressibility of water is a key factor.
• It reduces the energy demand to operate the hammer.
