Well Drilling Down The Hole Hammer

4'' DTH Hammer with External Diameter 99mm and 2 3/8'' API REG for Well Drilling

 

Product description:

A down-the-hole hammer (DTH hammer) is a tool that can be attached to the end of a drill string and inserted into a bore. It's a small jack hammer used to break hard rock into small particles that can be flushed away by the DTH hammer's air exhaust.It is one of the mainstream drilling technologies for mining and quarrying worldwide. Recent improvements have largely been aimed at making systems more fuel-efficient and at optimizing tool life.

 

Product Advantages:

1.Capable of drilling in almost all ground conditions.
2.Constant energy directly behind bit provides speed with less power loss and greater hole accuracy.
3.Rigid drill string improves hole alignment.
4.cost-efficient and environmentally friendly drilling
