The internal hook is a fishing tool generally used inside casings and oil tubings for fishing ropes and other fishes such as wire-lines, cables, logging wire-lines and paraffin cutters.

TIANHE Reverse Circulation Junk Basket (RCJB) is designed to remove all types of small junk objects from the well hole. The tool’s main feature is that it eliminates the possibility of pulling a wet string during fishing operation with its reverse drainage design. The RCJB can also be used as a fish magnet when fitted with a magnet insert, while maintaining its reverse fluid circulation feature.
