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)

3) Continuous flight auger and auger head
Flat or Butterfly Clay Auger (Single Cut Auger and Double Cut Auger)
Main Applications:
