Main Applications: 
1) Single Cut Augers and Double Cut Augers are suitable for drilling in medium to strong rock (15 ~ 60MPa)
2) Double Cut Augers are recommended for bigger diameters uncased boreholes.

 

2. Flat or Butterfly Rock Auger: (Single-Cut Auger, Double Cut Auger, Double Cut Auger without Rock Pilot)

Main Applications:
1) Flat or Butterfly Rock Augers are suitable for drilling in weak fractured rock and very dense sand and gravel (Less than 5 MPa)

2) 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)

 

3. Flat or Butterfly Clay Auger (Single Cut Auger and Double Cut Auger)

Main Applications:
1) The Single Cut and Double Cut Augers are suitable for drilling in clay, silt and loose to medium dense sand and gravel.

2) The Single Cut and Double Cut Augers with side cutters are suitable for drillin in hard clay, silt and medium to high dense sand and gravel.
