4"5"6"8"10"12" SD DTH Hammer with API REG Thread for Water Well Drilling
Product description:
A Down the hole drilling is the most critical component on a drill rig, and the DTH system has numerous advantages over other options.
DTH drilling offers several advantages over top-hammer drilling for larger, deeper holes in medium-hard formations. Because the hammer is at the bottom of the hole, power loss is minimal as the hole deepens.
Product Advantages:
1. The DTH system is easily adaptable to most directional drills in
a short period of time.
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. The air flowing through the hole ensures efficient flushing and
cleaner holes. With the same hammer, you may make a variety of hole
diameters.
