Underreaming

Decrease cost and risk

We have the most efficient tool for hole opening, underreaming, and casing milling, which gets the job done with the lowest cost and risk.  

The LOCKOMATIC™ underreamer offers fast run-in, positive expansion, positive locking, and positive unlocking. The LOCKOMATIC underreamer is as reliable as the drillstring itself because the lock is an extension of the drillstring. There is direct control of the tool, as if the lock were in the driller's hand.
