Hello Kevin,

I am not certain as to how this vendor achieves the holes in their materials,
but they are a well established vendor for drilled sapphire, they may be able to
help.

Does anyone know of a vendor that manufactures an Ultrasonic Drilling
Machine appropriate for drilling relatively-small holes (1 mm in
diameter) into glass wafers.
