ABSTRACT:
A threading device comprises a longitudinally adjustable, C-shaped frame configured with mounting heads at its open ends, the heads being arranged to interchangeably mount a collet for supporting a rod or pipe to be threaded and a threaded die guide shaft mounting a thread cutting die, the pipe or rod and the die guide shaft being secured by set screws so that their confronting ends are in aligned abutment with each other intermediate said mounting heads. Rotation of the threading die on the guide shaft moves the die onto the pipe or rod to form precisely arranged threads on the latter.
