It is a tool that allows the refrigeration mechanic to cut copper pipes to perform the operations of replacing the components or sewing pipes in the refrigeration or air conditioning system.
The copper tube cutter is constructed of duralumin and steel, which enables its compact shape, making it easier to handle.
In any case, the tube must be countersunk, because during cutting, a burr is formed at the inner end of the tube, which makes it difficult to insert the reamer.
