An internal hook is a fishing tool generally used inside casings and oil tubing for fishing ropes and other fish such as wire lines, cables, logging wire lines, and paraffin cutters.Designed and manufactured according to API spec 7-1. The hydraulic shock absorber, by means of compressible deformation of compressed liquid under the function of pressure, absorb the energy from drill bit and drill string vibration. Thus, the shock absorber can reduce the vibration and impact load of drill tools.

• It is generally used inside casings and oil tubing.
• It can salvage the wire lines, cables, logging wire lines, and paraffin cutters.
• It comes in two forms: a Dead (fixed) hook and a Live (adjustable) hook.

Junk Basket 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. Junk basket is normally attached at the bottom of the fishing string, lowered to a point several feet from the bottom of the well. Begin circulation of the junk basket to wash the hole. Stop circulation and drop the steel ball. (When the steel ball is dropped into the valve seat, reverse fluid circulation is activated.

• A lifting sub is provided for ease of handling which includes a storage space for the steel ball used in the operation of the tool.
• A single junk catcher is used in each assembly.
• Itco Junk Basket may be easily converted to a fishing magnet by replacing the catchers with magnet insert.

Junk Sub (Fishing Cup) is normally used to catch and remove junks that are too heavy to be circulated preventing them from settling at the bottom of the well-bore. Typical junks are shivers and fallen objects such as carbide tooth, drill bit and bearings which are too heavy to be removed from the well- hole through conventional fluid circulation. Junk Sub’s main function is to keep well bottom clean to increase bit service life, reduce and prevent drill bit from unexpected damage.

• Designed and manufactured according to API spec 7-1.
• The Junk cup can clean sundries at the bottom of the well.
• It can improve the service life of drill bit.
• It operators can get quicker, cleaner scraping jobs
