The Internal Fishing Tool (Tapered Mandrel Type) is designed to retrieve down hole devices by locating in the bore when the exact internal diameter cannot be determined due to damage, ‘wash out’, or wear.
The tapered mandrel allows expansion of the Collet to contact bore. The tool is run using the upper fishing neck. Downward jarring will set the Retrieving Collet and shear the Running Tool. The Pulling Tool is then run in, latching the inner fishing neck. Upward jarring sets the tool and retrieves the lock. To release from the Lock a reverse of the procedure will allow full retrieval of the Fishing Tool. The Fishing Tool can also be used for retrieval of tools with damaged internal fishing neck.
An alternative Pulling Neck is available should an external Fishing Neck be preferred.
Fishing Tools can be manufactured to suit any size required.
Part Numbers are available upon required.
