The Hydrobur-service jar is designed to free a drilling tool stuck in a hole by jarring against the stuck point.

Our drilling jar is a double acting hydraulic jar designed for use during drilling operations to apply an intensified force against a stuck portion of the drill string by jarring either up or down.


Our fishing jar is a hydraulic jar designed to free a stuck portion of the drill string by applying an impact force during fishing operations by jarring up and delivering upward impact force with a higher frequency than a drilling jar due to a faster recharge.


Our double acting hydraulic drilling jars and hydraulic fishing jars have a set of featured standardized assembly components that allow for the assembly of either of the models while manufacturing.



• Simple, robust and dual-use design

• One set of spare parts and accessories

• Drilling or fishing assembly manufacturing depending on operational needs and requirements

• Order-to-shipment time saving
