Instroction

 

DTH is abbreviation for "down the hole" . Low Air Pressure Down The Hole Drill Bit  (DTH Button Drill Bit) is used to produce large-diameter holes in rocks, usually in the initial stage prior to blasting, but it is also used in non-blasting applications. DTH drilling are used mostly in mining quarries but can be used in a variety of other constrauction applications. The DTH drilling method is growing in popularity, with increases in all application segments, including blast-hole, water well, foundation, oil & gas, cooling systems and drilling for heat exchange pumps. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards.
