Qualified High Air Pressure DHD360 DTH Hammer for Water Well Drilling and Mining
Product Description:
Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be efficient at crushing rock.
Down-the-hole (DTH) drilling has made it easier for contractors to drill wells faster and more efficiently, and to transition from dirt boring to rock boring just by adding a compressor and hammer to the drill bit.
Product Advantages:
1.Lesser time consumed compared to when the contractor has to be changed when geology changes.
2.Less wear and tear on the drill bit during drilling operation as the hammer is doing most of the work.
3.DTH requires a minimal amount of rotational torque to cut rock that also allows the hammer to drill straight.
4.Vibrations from the DTH percussive hammer can stimulate the formation to enhance production capability, reducing the need for hydraulic fracturing
5. Better borehole quality and accuracy
