The down-the-hole hammer cooperates with the down-the-hole drilling rig and the dth drill bit, and is mainly used in the construction of mining, marble quarry blasting hole drilling, water well drilling engineering or drilling and other engineering construction.

1. The drill bit does not require nylon tubes, thus eliminating the trouble of nylon tubes being broken, damaged and hard due to thermal expansion and contraction.
2. DTH hammer without nylon tube has low energy consumption, high impact frequency, and the drilling speed is 15%-30% faster than the same type of DTH hammer with nylon tube.
3. Because the structure is very simple and the components are reliable, DTH hammer is easy to maintain and has a longer service life.
