Down The Hole Drilling is a high-speed, clean, cost-effective and
highly efficient drilling method for deep drilling. The drilling is
carried out with a DTH hammer, such as Mission DTH hammer or
Mission 40 DTH hammer. The DTH hammer is capable of drilling up to
depths of several thousand feet, depending on the drill setup and
conditions. This method of drilling can reduce the cost of drilling
compared to traditional drilling methods and can achieve high
drilling speeds. The DTH hammer provides reliable and accurate
drilling performance and is ideal for drilling in hard and abrasive
rock formations. The DTH hammer is also capable of drilling through
soft and unconsolidated soils and can be used in a wide range of
drilling applications.
