Thanks, Do I need to constantly pour water on it, or just make sure it stays wet?
don’t know how serious about it you are but there are table top glass grinders and the bit is a diamond dust drill. You keep water in the port and there is no dust when using it. It has a small sponge that soaks up the water and keeps the drill wet, they are expensive so you never grind glass dry. Your best bet is to find a glass shop and visit. You will get all the info you need, but if you fall in love with the glass like I did, it can become an expensive hobby....There are 100’s of colors and types of glass, all beautiful. GG
