Taper taps D1-D5 (Д1-Д5) fishing tools

Universal taper taps are used where a part of a drill string left in the well is ended with a sleeve, a lock or a nipple, as well with a butt end of the pipe. Core barrels and casing pipes are also extracted with the use of universal taper taps.

Special taper taps catch only by gripping the thread of washers, locks or nippels. The choice of such taper tap depends on the type and condition of thread which is defined by the ultimate connection of the elevated column.
