Product Description

Product Introduction
DTH is short for "down-the-hole". Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanism followed the bit down into the hole.
DTH drilling can be performed in most types of rock, hard or soft. It's a commonly used method in the mining industry (blast hole drilling), waterwell drilling, construction, and in the oil and gas industry. In DTH drilling, the drill string rotates while the drilling hammer continuously strikes down into the rock.
