Drilling holes in beach stones to use for beads

When drilling beach stones, I would suggest you avoid the advice about buying the best drill bit you can find. When drilling stone, diamond bits wear out quickly, whether you buy the twisted ones (expensive) or the straight ones (far less expensive.) So go for the straight ones. I’d suggest you go for the economy diamond cylinder drill packs watches from Rio. They come 25 in a pack and cost less than a buck each, compared to $2 or $4 each for twist bits. You can get through five or six stones with a single bit if the stones are not too hard. Start your hole with a diamond ball burr, say 1 mm Hold the stone underwater with your hands in a small plastic bin, like Tupperware or glad disposable. Make a small, round divot in the stone.
