The SUPER-MAXBIT achieves a stable and balanced drilling system
for various collapsing overburden formations. This is an advanced
technology compared to the other eccentric drilling methods. It
consists of two to three bit wings connected to the Down The Hole
Hammer.
The bit wings are extendable/retractable when the drill string rotates
in the forward/reverse direction. Drilling and casing are possible
simultaneously with the use of a casing shoe.
The SUPER-MAXBIT has the fllowing advantages:
- High-speed Drilling similar to a standard DTH bit
- Straight Hole Drilling
- Uniform rotation while drilling of boulders, sand and gravel
- Reliability of extending and retracting proven by customer
experiences
APPLICATIONS
The SUPER-MAXBIT is designed for drilling in gravel, clay, sand
mixture, boulders and easy collapsing overburden. The system is
applicable for the various intentions with the combination of ap-
propriate rig and drill.
