What they said. You can tell the stronger discs by the appearance of fibers on the sides of the wheel. Normal are smooth and are dangerous when they shatter.
Plastic goggles are better than safety glasses. Face shields are pretty good too, but some kind of eye protection is necessary, these things spin up pretty high.
My best use of the Dremel is cutting rusted nuts/bolts, and cutting slots in tubing. I've used one for precise drilling also, using ordinary highspeed twist drills.
