• the basic idea of the invention is to create such a portable instrument, which, in turn, should be avoided.
• the task posed is solved in order to save the portable tool in the same way as the second one.
• a freewheeling tool for installing internal threads with an external plug-in in tandem with the non-removable plug-in allows you to connect to it.
• Phases are installed on the shunts
• a non-portable tool works with the following
• the waxing up due to the action of the friction forces between the grooves of the 6, 7, 8 and the lost rings causes the thread to start to rotate.
• the grooves 6, 7, 8 start the helical groove with a step, the same step as the thread being cut.
• the non-self-contained tool may be used only in the case of the intrinsic pressure by means of a slot with a 25 mm slot.
