There are three categories of conical rock augers:
A) Single-cut Single-spiral
B) Double-cut Single-spiral
C) Double-cut Double-spiral
Drilling Diameter Range: 500~2500mm
Main Applications:
1.Single Cut and Double Cut Augers are suitable for drilling in medium to strong rock (15~60 MPa)
2.Double Cut are recommended in bigger diameters uncased boreholes.
3.Single Spiral provides high drilling speed, easy cleaning and low rotary resistance
4.Double spiral has better guiding property and efficient carrying-soil capability
