I am starting to drill holes in stone with a dremel and diamond burrs, can some one tell me if there is a diff type of bit to drill through stone and glass? If so the best place to buy them like diamond burrs. Would also like to find a good tutorial on drilling stone.

Diamond "wire drills" look like cylinder burs but smaller. Sizes run from .75 mm up to 2.5mm or so. Bigger drills are available in core drills. Kingsley, Lopacki, and others have Chinese drills. Lasco Diamond Products are made in CA with real diamond (cost more). You can also by "sintered drills" which last longer but cost even more. A good drilling DVD is by Marzee and advertised in Rock & Gem. It is twice as long as needed but you will definitely learn to drill.

Holding your breath while drilling under water is the hard part. Actually, submerge the rock and drill using a very light pressure and back off. This pecking motion allows rock dust to rise and not clog /overheat drill. Most the wire drills are glued rather than plated so diamonds strip off if overheated.

Or go to Micheal's (Craft store) or online orders.
They have a rock drilling machine for $30. It's kind of a kids thing but hey ! I am going to get one eventually. It is electric and has a see through enclosed dome so no rock dust.

I've seen carving stations made basically of a plexi top, front and back to contain water spray while carving or drilling. Any drilling will have to be done with water or drills will wear out or strip of diamonds very quickly.
