12. Describe the methods of forming screw threads on ends of conduit and of using appropriate tools to remove all sharp edges and burrs?

Screw threads on conduit ends can be formed using either a threading machine or a hand-held die, which cuts threads into the metal. After threading, it is essential to remove sharp edges and burrs to ensure safety and proper fitting; this can be accomplished using a deburring tool, file, or sandpaper. A reamer may also be used for a smoother finish on the threaded edges. Regularly inspecting and maintaining tools will enhance the quality of the threaded ends and reduce the risk of injury.
