Product catalog summary
Introduction
A Down The Hole (DTH) drill, commonly referred to as DTH, is essentially a jackhammer attached to the bottom of a drill string. It is designed to break hard rock into small cuttings and dust, which are then evacuated by a fluid. This method is one of the fastest for drilling hard rock. The boring device, used with a pile driver, creates holes in rocks and unreinforced concrete. Compressed air is required for the percussion of the tool and to remove dust from the hole. The air must be lubricated to prevent damage to the boring head.
