1. Keep faster drilling rate, stable and continuous sampling.
2. Simple internal structure with components of high rigidity,
thus ensured hammer life and convenience of maintenance.
3. The sample tube uses an integrative design and can be replaced
without disassembling the hammer.
4.Carburizing treatment and good abrasive resistance.
5. Bits designed with patent. Simply by reaching the drill bit, the hammer can drill holes different from sizes and ensure that the sample is not contaminated.
6.In tough conditions such as loose soil, hard rock and plenty of water exist, sampling can be done well.
