125mm High Strength Hard Rock HDD Pilot Hammer System


Features

1. The drill bit has high-speed rock impact force, high rock drilling speed and high rock breaking efficiency.
2. The drilling quality is high and the drilling speed is fast, without grinding.
3. High-efficiency drill bits can be optimized and customized according to the rock structure.


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%.

Introduction
Use HDD Pilot Hammer with drilling rig and corresponding drilling tools for percussion rotary drilling. The HDD pilot hammer is connected to the bottom end of the drill pipe. The drill rig drives the drill rod to rotate. Compressed air enters the HDD pilot hammer through the drill pipe to generate 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. Because the outer diameter of the HDD pilot hammer is smaller than the drill diameter, it can be lowered into the hole as the drill depth increases. Compared with the pneumatic drill outside the impact hole, the impact power loss is small, and it can drill deeper holes.


Field of use
This method is suitable for drilling into hard rock formations, the drilling is not easy to deviate, and it is more advantageous to use in water-deficient areas. It is used to drill into hard rock and pebble layers, and the drilling efficiency can be increased several to ten times compared with conventional rotary drilling and mechanical percussion drilling, and it has been promoted as an advanced technology. Its application fields have been expanding. In the past, it was mainly used for drilling blast holes in mines, but it has been used in hydropower, railways, highways, water wells, building foundation piles, and geological prospecting.
