I've been doing a lot of research online and finding only a lot conflicting information. I'm hoping some of you with experience can tell me what you would recommend.
I want to drill through sea shells. Which kind of diamond tip bit is best? Twisted, cylinder, or?
Also, any advice about drilling shells is appreciated. Here's what I do know about it: Wear a dust mask and goggles, and they get quite hot, so it's best to drill them submerged in water.
Would using a spray bottle of water to keep spraying them work as well? Any advice on how to keep them still while drilling, since I don't have a press? I plan to buy a small Dremel for fine work.
Thanks in advance.
