Introduction
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. Since the outer diameter of the HDD pilot hammer is smaller than the drill bit diameter, the pilot hammer can be lowered into the hole as the depth of the drill bit increases. Compared with the pneumatic drill that impacts outside the hole, its impact power loss is small and it can drill deeper holes.
Features
1. The drill bit impacts the rock fast, the rock drilling speed is fast, and the rock breaking efficiency is high.
2. The drill bit has high wear resistance and can hit more meters.
3. The drilling quality is high and the drilling speed is fast, without grinding.
4. High-efficiency drill bits can be optimized and customized according to rock structure.

Field of use
This method is suitable for drilling into hard rock formations, and the drilling is not easy to shift, and it is more advantageous to use in water-deficient areas. Used for drilling hard rock and pebble layers. Compared with traditional rotary drilling rigs and mechanical impact drilling rigs, its drilling efficiency can be increased several to ten times, which is an advanced technology. Its application areas are expanding. In the past, it was mainly used for blasting and drilling in mines, but has now been used in hydropower, railways, highways, water wells, construction pile foundations, and geological prospecting.
Advantages
1. The hard alloy tooth material adopts high wear-resistant formula, and the tooth breaking rate is less than 2%.
2. The body of trousers is made of high-strength high-quality alloy steel. After advanced heat treatment, the rate of broken trousers is less than 1%.
3. Using advanced CNC machining and advanced alloy tooth assembly technology, the tooth loss rate is less than 1%.
