DJ10A | Double Acting Hydra-Mechanical Drilling Jar

The DJ10A drilling jar was redesigned with a larger ID than comparable 500 series drilling jars to effectively increase customer MWD retrievability success rates. It remains one of the toughest and most durable in the industry, and it’s two way action allows hydraulic operation upwards and downwards. Cougar’s proprietary internal mechanical latch (Figure 1) assures that the jar will not accidentally fire while tripping or making connections.
