Cased Augers & Heads
Temporary Thrust Casing and Auger assemblies are positioned directly behind a reaming head, which follows the pilot tubes. The reaming head increases the bore diameter, and the augers transport spoil to the launch shaft.
The Integral Bearing Swivel Cutter is an upsizing tool between the pilot tube adapter and the lead thrust casing. It is used in ground conditions above 35 blow count and functions to keep the pilot tubes stationary. Simultaneously, the cutter bit rotates to excavate the soil, and fluid ports release lubrication to reduce cutting torque. Integral Bearing Swivel Cutters are available in standard and HD models to match the thrust casing assemblies.
