Cougar DJ-10 Double Acting Hydra-Mechanical Drilling Jar

The DJ10 is assembled with the same dependable mechanical lock (latch) mechanism as the Cougar DS DJ6, but with the capacity to jar down hydraulically.

All Cougar DS jars have internal locking mechanisms that eliminate the need for “safety collars” found on many other jars. Even better, the internal lock ensures the tool will not misfire.

Cougar DS has been designing and manufacturing downhole drilling tools since 1969 and nobody does it better. An ISO 9001 accredited company since 1992, our in-house manufacturing, quality control and strict material specification ensure complete control for high performance drilling tools.

Cougar DS is the premier supplier of downhole drilling equipment that sets the standard by which all others are judged.
