long story short, yes.

Used them several times for a large number of problems and they work well, but it must be drilled as straight as possible.

100% you can coil that, I would have it done by a machine shop if possible to get that spot on straight, i did one myself on a Side stand bolt on my bike and the side load from it not being perfect pulled it out over time.

I'd only use a timesert, as you have a second chance if it ever pulls out (and I've never had one pull out).

If you get the right set, it comes with a guide etc.
