Description


DTH hammers are used for blast hole drilling and water well drilling project.Working with DTH drilling pipe and DTH drill bit, mainly applied in Mining,Marble quarry or well drilling and other construction projects.


1. Based on previous experience of ordinary hammers, combined with the features of reverse circulation hammer, optimized internal structure and ideal energy transfer, thus ensuring the series of hammers drilling with fast, smooth and continuous sampling.

2. The internal structure is very simple with components of high rigidity, thus ensuring long life and easy maintenance of the hammer.


3. The collection tube adopts an integrative design and can be replaced without disassembling the hammer. With carburizing treatment, it has good abrasive resistance.


4. Equipped with bits designed with patent. Simply by replacing the drill bit, the same hammer
can drill holes of different sizes ensuring that the sample is not contaminated.


5. In difficult conditions such as loose soil, hard rock and plenty of water exists, sampling can be done well.
