DJ10 | Double Acting Hydra-Mechanical Drilling Jar

The DJ10 drilling jar remains one of the toughest and most durable in the industry. The two way action of the jar gives the operator the ability to work the tool both, upwards and downwards. This particular jar operates hydraulically in both directions, downward and upward. Cougar’s proprietary internal mechanical latch (Figure 1) assures that the jar will not accidentally fire while tripping or making connections.
