Tool Joint Identifier


The tools joint identifier is a kind of measuring tool, mainly used to measure and identify the size and type of the drill pipe quickly.

The tool joint identifier is a simple and effective way to determine most oil field rotary shouldered connection types. This can be an invaluable tool when the connection identification marking is worn or in question. 

The tool joint identifier can also be combined with a drill bit nozzle identifier, which is used for checking the bit nozzle orifice. Both measuring instruments are combined into a compact and portable ruler format that can be made readily available should a question arise in the field.
