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.

The DTH system, generates clean, truly aligned boreholes at high drilling rates with little operational cost, can drill small diameter holes and deep holes.

Product Advantages:
1. Service and Maintenance are simple.
2. Extensive chip drilling allows for faster drilling with less dust.
3. Hole alignment is improved by using a rigid drill string.
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.
