I would be choosing a thread file as the tool for this job…. then run a die over it.

A die, right?[img]

I’ve used this thing to repair threads. It works great. Twist the knob to put the two cutting blades into the thread and then turn to clean up the threads. It works in a similar fashion to a pipe cutter.

Yes, die.

The problem with that tool is the length of the threads usually is not long enough for it to work. You may get lucky if it’s in the right spot. I have that tool and rarely use it.

It works well for light weight stuff but may not be enough for crank threads. I’ve used it successfully on a rear axle thread.
