2-      Flat or Butterfly Rock Auger

3-      Flat or Butterfly Clay Auger

1) Conical Rock Auger

There are two categories of conical rock augers:

a)      Single Cut Auger

b)      Double Cut Auger

Drilling Diameter Range: 500~2500mm         

Main Applications:

i) Single Cut and Double Cut Augers are suitable for drilling in medium to strong rock (15~60 MPa)

ii) Double Cut are recommended in bigger diameters uncased boreholes

* Other sizes can be manufactured as per customer demand

Features:

1-      Rock Pilot

2-      Hard facing strips on flights for wear protection

3-      Kelly box size as per customer demand

2) Flat or Butterfly Rock Auger:

There are three categories of Flat or Butterfly Rock Auger:

a)      Single Cut Auger

b)      Double Cut Auger

c)      Double Cut Auger without Rock Pilot

Drilling Diameter Range: 500~2500mm      

Main Applications:

i) The Single Cut and Double Cut Augers are suitable for drilling in weak fractured rock and very dense sand and gravel (Less than 5 MPa)

ii) Double Cut Augers are mainly used for bigger diameter uncased boreholes and secant piles

iii) Double Cut Auger without rock pilot are recommended for fractured rock or moderately weak to moderately strong rock (5~50 MPa)

* Other sizes can be manufactured as per customer demand

 Features:

1-      Rock Pilot

2-      Hard facing strips on flights for wear protection

3-      Kelly box size as per customer demand

3) Flat or Butterfly Clay Auger

There are two categories of Flat or Butterfly Rock Auger:

a)      Single Cut Auger

b)      Double Cut Auger

Drilling Diameter Range: 500~2500mm     

Main Applications:
