My hubby hooked me up with an old school drill press for my stamping room:

I drilled slow, in a little, take it out, let it cool (like 5 - 10 seconds) drill in a little more, take it out. I had no breakage when I started this process. It took about 7 to 8 in and out's to get the hole done. (Also, you'll need to vacuum up the ground domino. Don't blow... what a mess.. have your vacuum handy.
Have fun!
