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%.

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.
