Beats me. They probably don't know either. You can generate plenty
of heat at 500 rpm.
Like I said, if I ever get a screw or nail in a tire, I'll just get a
plug kit. Or take it to a nearby Just Tires. Done that too.
If I can't find a puncture, I assume it's a rim leak. But one time
they found a nail I had missed.

The point here is to learn.

It's sort of like a biology lab.

Nobody forces you to cut open a pig, but, we all cut open pigs and
frogs and shrarks to study them.

That's sort of why I'm doing this. (The tire is ruined already anyway,
because I drove on it for about a mile, assuming, wrongly, that it
still had enough air.)

Today I went to a few shops but I had to do other errands.

So far I've second sourced the first two of the three fluids.
1. Inner liner solvent === MEK paint thinner
2. Patchplug vulcanizing cement === available everywhere
3. Inner liner sealer === need to find a source for this tar

I was gonna go to Harbor Freight to see if they have the carbide bit,
which is, I think, the most critical tool for doing the job right.

Apparently the carbide bit is to smooth the broken steel belts.
Am I correct in that being the purpose of the fluted carbide bit?
