	I can't believe this is about to come in handy,
	but...

	I have done exactly what you're proposing, although
	with an i387 math coprocessor.  You will need to 
	visit your local hardware store and purchase a
	diamond-tipped masonry bit.  Use it at relatively
	low RPMs with steady pressure - a drill press is
	best.  Also, having a spray bottle with water to
	keep the surface and the bit wet will help prevent
	the insulation from splitting.  Good luck!
