Rock Drilling Auger adopts the high-carbon steel and special
drilling bits angle to keep the drilling strength and efficiency.
There are three types of drilling auger:
1) Continuous Flight Auger and auger head
Different types of couplings being used as per the torque, drilling
diameter and depth;
Quadrangle, hexagonal and octagonal coupling available;
Coupling with high-quality material proceeded by CNC machine and
heat teratment;
2) Conical Auger (Single Cut Auger and Double Cut Auger )
Drilling Diameter Range: 600~2500mm
Main Applications:
Single Cut Augers and Double Cut Augers are suitable for drilling
in medium to strong rock (15~60MPa)
Double Cut Augers are recommended for bigger diameters uncased
boreholes.
FEATURE :
1 Single Cut Augers and Double Cut Augers are suitable for drilling
in medium to strong rock (15~60MPa)
2 Sturdy and wearable rock pilot for accurate positioning
3 Hard facing strips for wear protection and service life extending
4 Kelly box size as per customer demand
