That's pretty much what I thought too.
I cut fiberglass and acrylic from the finished side too.

Definetly.

If you have a drill press it will make the hole much cleaner.

If you really don't want to slip...

1. Use a drill bit the same size as the the hole saw's bit to start.

2. Use the hole saw and spin the drill in REVERSE-to start the cut. You just want to break the surface. This keeps the blades from grabbing and messing up the your new surface.

3. Put the drill in forward- Drill away.

I usually stop just before I'm through-and hit the other side to finish it off. This save a LOT of time trying to get the cut piece out of the hole saw.
