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 has the feature of efficiency and flexibility.  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.

DTH drilling tool is a kind of drilling system which uses compressed air as motivation, makes drilling impact motivation parts down the hole, to control the piston reciprocating motion by the distribution device in the hammer, and then impacts the DTH bit in the front of the hammer to transit the impacting power to the bit. The DTH bit in the front of the hammer breaks the rock to drill hole.
