Characteristics of ZRC6A-DHD360 impactor

1. It is mainly used in ground sources, water well markets and mines that require drilling operations of more than 150mm.

2. The matching drill bit does not require a nylon tail tube, so it saves the trouble caused by the fracture, damage and thermal expansion and contraction of the nylon tail tube;

3. The impact energy loss is low, the impact frequency is high, and the drilling speed is 15%-20% faster than the same type of impactor with tail pipe;

4. Low air consumption, saving wind and fuel, saving more than 10% fuel than the same type with tailpipe impactor;

5. The internal structure is simple and reasonable, and the maintenance is convenient; the parts have good consistency, high reliability, low overall failure rate, low disassembly frequency, long impact life, and low use cost.
