High Productivity DTH Hammer for Well Drilling (DHD, SD, QL, Mission, Numa, Cop)
Product Description:
When you need to drill high quality holes with diameters between 100-254 mm, DTH (Down The Hole) drilling is by far the best and most effective method. 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.
Product Advantages:
1. Better borehole quality and accuracy
2.Lower operating costs, as the same drill will be used for drilling through dirt and rock.
3.The use of air makes this method very cost-effective as air does not have to be sourced, transported or treated.
4.Less amount of drilling fluid and additives are required.
5.Less weight-on-bit allows for lighter rigs that are easier to set up and takedown.
