  • Accommodate Range II Drill Pipe
  • 4 in. (102 mm) Fluid Course permits 1,000 U.S. Gallons (3,785 L)/per minute flow
  • 10° - 18° Variable Drilling Angle
  • Floating Spindle™ Allows Simple Makeup and Breakout
  • Dedicated Pumps for Rotary and Thrust
  • Run-On-One-Technology-System (ROOTS) capable
The Wiggle Steer® System provides the operator of a directional drill the means to rotate the drill pipe and subsequently the cutting head on the drill string back and forth over a predetermined range. This back and forth motion would cause the hole made by the cutting head to be more open in a particular direction and therefore facilitate steering of the drilling pipe in that direction under ground.

The Wiggle Steer System will rotate the Drill Pipe in the Makeup (CW) direction while thrusting forward. It will then rotate the Drill Pipe in the Breakout (CCW) direction but will not thrust in the breakout direction. This method reduces the breakout torque and should prevent the drill string tool joints from parting down-hole.
