Slide Reamers:

The Dynomax Slide Reamer combines the drilling, conditioning and reaming phases of an operation into one stage. Slide Reamers reduce wiper trips and rig time and can reduce rotary torque by 15-20%.

Mud Motors:

Our motors offer multiple configurations to provide your drill string with optimum performance while reducing loads, pressure and vibration. Our motors can also drill large-sized holes suitable for larger rig assemblies.

Shock Subs:

Our shock tools lengthen the life of your drill string and reduce vibration and load, protects the instruments in the assembly and increases the efficiency of your drill string.

Drilling Jars:

Dyno-Jars meet a wide range of demands, including high temperature and extreme conditions, while greatly improving pull accuracy and increasing oil flow.


The RegulatorTM employs a variable size exit orifice to actively moderate the flow that goes through the motor continuously – extra fluid is vented out the side.
