How do you drill a hole through a small rock?

In: Rockhounding and Mineral Collecting

In a bowl of water use a diamond tip drill and cover the stone with water.
you need to use the drill with very little pressure and drill half way then drill from other side to keep from breaking out the sufface of the hole.

The drill RPM needs to be at least 10,000 - 15,000 RPM.
