If you are done with your hole. Consider it a win.

Thanks for this. No er but the whole process felt dangerous. Figured I was doing something stupid, and maybe it was. Hole is perfect.

Plywood glues can be brutal on non-carbide teeth. It's likely the heat on the hole saw caused metal expansion which also caused additional binding and even more heat.

I don't think so. I spent way more time recovering from the binding than actually drilling. Teeth are still super sharp. Drill was toasty though, had to stop and run it to let the hot air out because the heat was hurting my silky hands.
