Threading a pipe is easy, but you do need to use the proper die size. If you're not sure how big your pipe is, measure from exterior to exterior to determine what size die you need. As long as you remember that it's the outside diameter you need, you won't have any issues.
Place your pipe in a vise to hold it steady while you work.
Position a bucket or old towel under the end of the pipe to catch your mess. Cutting oil and metal shavings will drop from the pipe while you work and are easier to clean up when they are contained.
Choose the correct die and place it in the stock at the end of the ratcheting die handle. Most dies simply push into place on the end of the handle.
The trick to successfully starting the threading process is to apply pressure to the die when you first begin threading the pipe. All you need to do is put the die over the pipe and push on the end facing you as you start to use the threading tool. This isn't hard to do, but failing to apply a bit of pressure to the end of the die will allow it to spin without cutting into the pipe.
Drizzle some cutting oil onto the end of the pipe.
Slide the die over the end of the pipe.
Push on the die, leaning into it a bit to apply some pressure to the end of the pipe. While pushing on the die, pull up the ratchet handle. You will feel the die bite into the pipe and begin to cut.
Release the pressure you've been applying to the die.
After the die has started cutting the thread, you'll want to continue threading the pipe. As you work, however, little shavings of metal will be cut into the threads. These are called chips, and you need to remove them every so often as you work. Known as breaking the chips, this process simply involves reversing the ratcheting action on your die handle for a turn.
Continue turning the die handle as you would a ratchet and socket, pushing the handle backward when you run out of room.
Stop every three or four turns and apply more cutting oil to the pipe. Squeeze the oil right down into the die to keep both it and the pipe well lubricated.
Flip the switch or turn the knob to reverse the ratcheting direction on your die handle. Give the handle 1/2 or 1/4 of a turn in this new direction to break the chips.
Return the ratcheting action to its original direction and continue turning the handle. Repeat the process of turning the handle, oiling the die, and reversing the ratchet for a few turns until the end of your pipe sticks out two or three threads past the teeth on the die.
Flip the ratchet in the backward direction once again and keep turning the handle until the die comes off the pipe.
Wipe the cutting oil off the pipe and off your die before putting it back into the pipe-threading kit for storage.
