HAMMR Drill

1 L, Length of stator 3 Based on in-house overpull testing 2 Dependant on the RPM of the motor

» Increases ROP and reduces NPT » Protects against stalling and friction » Activates with resistance at the bit/mill » Requires less specific energy to mill » Adjustable impact force » Replaceable wear components

Our HAMMR Drill motor combines the function of a percussion hammer with the drilling action of a drilling motor.

The HAMMR Drill motor uses a mud lubricated cam mechanism powered by the rotor of the motor to accelerate the hammermass. The hammermass strikes the bit box several times per second, delivering an intense percusion force overlayed on the bit or mill. In addition, reactive percussion forces cause the motor housing and drill string to vibrate, reducing friction between the wellbore and drill string or coiled tubing. Designed for long-life, the hammermass and thrust bearing balls act as wear components and are easily replaced and serviced.
