The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.
