DHD 3.5 Inch High Air Pressure For Ore Drilling Down The Hole DTH Hammers
Application: The down-the-hole drilling tool is used to drill large-diameter holes in rocks, usually in the initial stage prior to blasting, but it is also used in non-blasting application.
DTH drilling are used mostly in mining quarries, but can be used in a variety of other construction application.
The DTH drilling method is growing in popularity, with the increase 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 underground DTH method, where the direction of drilling is generally upwards instead of downwards.
