The worst thing about a Dremel tool, is that the speed is TOO fast.
I presents a danger in that you can cut the heck out of yourself, plus
you need to wear good safety glasses, possibly cutproof gloves.

If you can stabilize the bone, keep it immobile, then it seems safer, also
long term cutting creates big time heat!  Hopefully Dremel could address
the fast speed even on low settings.  Just be very careful, four hands is
true, the fourth chases the specimen when it jets off across a counter.
