Pipe and Conduit Thread Dies

Create external pipe and conduit threads. These dies are shaped for use with a die wrench. Loosen and tighten the die with the included set screw to adjust thread depth.

Carbon steel dies are for use on most metal and plastic. High-speed steel dies last longer than carbon steel when cutting similar material.
