Drilling coral

I have about a pound of nice Mediterranean coral chunks about 1/2"
cylinders. Does anyone know where I could get it drilled?

Meredith Ott

Coral is easy to drill with ordinary steel drill bits. Just try it.

How do you want it drilled? Across the diameter to make a drop sort
of bead, or through the length ? More would be useful.

And wear a mask!

And use a good dust collector as well as a mask. The mask protects
you while you’re drilling. The collector keeps the dust from
collecting on studio surfaces.

Tampa Bay coral is very hard. You will have to use several diamond drill bits for some drilling of this material.
