EWD®5 (Enlarge While Drilling)

The EWD®5 is a fifth generation underreamer tool that is mechanically activated and remains set in the tripping position to drill the cement and shoe. Once clear of the casing simply add weight to activate the 3 cutter blocks to their full gauge enlarging size. The locking mechanism ensures the EWD®5 remains open to drill a full gauge hole.

Benefits:

Easily steer and orient below a directional motor due to short length
Proven durability and reliability maintaining a full gauge enlarged hole
No lateral vibration, prevents MWD, LWD and motor failures
Freedom to choose any pilot bit PDC or Tricone
Drill float equipment-saving trips

Features:

• Three blade concentric cutter design creates balanced cutting action
• Locks in enlarged reaming position
• Using a full gauge bit, the EWD®5 cutters drill only 25% of the hole
• Rigid cutter blocks with PDC diamonds supported by a solid steel mandrel
• Three nozzles improve bottom hole cleaning.
