Clay/Soil/Earth/Rock Drilling Auger adopt 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.
3) Flat or Straight Auger: (Single Cut Auger, Double Cut Auger, Double Cut Auger without Rock Pilot)
Main Applications:
Flat or Butterfly Rock Augers are suitable for drilling in weak fractured rock and very dense sand and gravel (Less than 5 MPa)
Double Cut Augers are mainly used for bigger diameter uncased boreholes and secant piles.3- Double Cut Auger without rock pilot are recommended for fractured rock or moderately weak to moderately strong rock (5~50 MPa)
- Flat or Butterfly Rock Augers are suitable for drilling in weak fractured rock and very dense sand and gravel (Less than 5 MPa)
- Kelly box size as per customer demand
