Product Description

Advantages

1. Adopts latest rock drilling theory, optimizing the internal structure and air distribution size, thus making the DTH hammer obtain the optimal energy transfer and achieving fast drilling speed and low air consumption.

2. Safe and reliable anti-drop device for drill bit is special designed to solve the problem of difficult salvage when drill bit break.

3. The check valve with different sizes of adjustable air hole can be replaced to provide more efficient slag discharging.

4. Easy to disassemble because the top sub and drive chuck adopt special thread.
