A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill. .
DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling. .
A is first thought to have been used for rock drilling in 1844. Many quarries used hand held tools that required the driller to suspend himself from a rope over the. .
In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the fluid (air, water or drilling mud) used to. .
DTH products can be used in the following applications:• Mining- drill and blast holes in open pit mining, where the drill operator will drill several holes, then.

When drilling a water well through the hard rock, no drilling method is as efficient as a DTH Hammer energized by the right air compressor providing high enough pressure. Softer grounds may also be drilled by air flushed rotary drilling, demanding a lower pressure air..
Air pressure requirement: The air compressor must provide sufficient air pressure to overcome the formation resistance encountered by the drill bit and maintain the drilling force. Typical air compressor pressures range from 7-30 bar (100-450 psi).
