SteeringWheel® bits combine the directional properties of roller cone bits with the ROP performance of PDC bits You no longer have to choose between directional control and superior performance. ReedHycalog®'s SteeringWheel bits are designed to give you the directional response and low reactive torque of a roller cone bit and the high penetration rates andlong life of a PDC bit.
The many benefits of the gauge ring prevents outer cutters from biting into the formation at gauge. This feature centralizes the bit, restricts lateral movement, reduces bit whirl, and thereby increases cutting structure life. Since the bit drills more smoothly, torque fluctuations are lower, the borehole is smoother, and weight transfer is more predictable. Faster penetration rates are maintained when sliding, and far less time is spent orienting the bit.
Not only does the gauge ring help to protect gauge cutters from radial vibrations, it also ensures that the back corner of the gauge is always in contact with the formation for more controllable, more predictable steering.
SteeringWheel bits also minimize reactive torque spikes as they drill, so reducing the likelihood of stalling the motor. Also, reducing peaks in bit torque means you get a smoother toolface response, so orienting the bit is more straightforward.
In terms of stability and steerability, SteeringWheel bits offer real advantages.

ReedHycalog recognizes that one SteeringWheel bit design cannot be universally applied in all directional applications. We have developed a complete product line of Full Ring and Part Ring designs addressing a number of needs, including lighter set bits, gauge design variations, cutter size and type variations. SteeringWheel designs use Non-Planar Interface (NPI) cutters as standard but the cutting structure can be enhanced for any number of applications through the use of TReX® cutters, DiamondBack™ cutters, Hybrid PDC bits, upreaming cutters and by incrementally increasing rake angles of the cutters.

Computational Fluid Dynamics (CFD), allows ReedHycalog design engineers to test hydraulic designs before building the bit. The designer is able to maximize hydraulic efficiency by ensuring high fluid velocity at cutter / rock interface while minimizing re-circulation and stagnant zones. CFD also lead to the development of SwitchBlade® hydraulics which is used on a number of SteeringWheel designs.
