Porter Cable router got cross threaded, not the collet side. Need to get the right size die. It is for the standard size spindle. Can someone please let me know what I need?
Thank you for your time!

Have you looked up the spindle to see if they listed the part number along with the thread data? Which model number?

690 is the model

Perhaps a thread file will do. Is that 1/4 or 1/2? unlike you I do not have all model numbers memorized.

15/16 sound good? maybe 16, 18, 20, 22, 24, 32 tpi would be a standard.

Do you have a thread pitch gauge? https://en.m.wikipedia.org/wiki/Thread_pitch_gauge
Auto parts store has them.
Is this the spindle? Pic is not good but should be able to tell.
If it is you can try calling them about the threads.

I doubt you will easily find a tap the right size. When you do it's likely an industrial quality one. It may well be cheaper and easier to replace the armature in that router.
Contributor
How bad is it? I’d probably just file the start thread by hand to repair it.

Once you tear, break, or cross thread something, there is no steel left to thread. If you try and run a die, it may or may not catch at the same place and anything that looks like new threads will not line up with good threads further down. That armature is toast.
Contributor
It depends on how awful the thread is, if it was just started and the user stopped, then a light touch up with a file is enough. If the user forced it, then yes it should likely need replacement.

I am trying hard to figure out how one would cross-thread this collet. I insert bits and thread/tighten the collet by hand until snug and then finish with the wrenches.

It can happen when changing back and forth between collet sizes.
I'm really, really careful about this with the spindle on my CNC machine because buggering the threads could me thousands of dollars to replace things since it would not be DIY...
