Use HDD pilot hammer to cooperate with drilling rig and corresponding drilling tools for impact rotary drilling. The HDD guide hammer is connected to the bottom end of the drill rod. The drill rig drives the drill rod to rotate. Compressed air enters the HDD pilot hammer through the drill pipe, generating a certain frequency of impact force to break the rock. At the same time, the exhaust gas is used to cool the hammer head. Drain the debris from the hole.
1. The hard alloy tooth material adopts high wear-resistant formula, and the tooth breaking rate is less than 2%.
2. The trouser body is made of high-strength high-quality alloy steel. After advanced heat treatment, the breakage rate of pants is less than 1%.
3. Adopting advanced CNC machining technology and advanced alloy tooth assembly technology, the tooth loss rate is less than 1%.
