Finally got it done! Thanks to all for your input. All info was good but when you have tiles this hard and brittle, this is how to do it. A friend of mine who works in tiling gave me the instructions.
Most important is to use a drill press. No one can hold a cordless drill this long without painful wrists. Use moderate pressure at all times to prevent breaking the tile.Each hole took an hour to complete. The bits must be kept as cool as possible using water and a sponge. Contrary to a common drill bit, you are grinding the hole instead of cutting it, thus a whole lot of friction is involved. First determine the hole location and use the diamond hole saw without the pilot bit to mark the outer rim of the hole. Replace the hole saw with a 1/8 inch glass cutting bit and drill through the tile at every 1/4 inch following the mark done previously with the hole saw. Keeping moderate pressure and the bit cool is the key to success here Clean up the sides using the hole saw.
