About to commence tiling in bathroom and need to cut approx 1 inch
diameter holes though normal wall tiles for shower connections to
protrude though. Not aware of tile cutting hole cutters and wonder if
normal hole cutters will do if well lubricated/cooled with water.

Any tips/ideas??

If you look back through recent archives of this group you will see a
reference to 365drills.net.

I've used their drills in small sizes and a 55mm one for a faucet. It
worked well on limestone. In some cases I drilled the tiles in a
water bath before fitting them. In others I drilled in situ and had
an assistant spray water on the cutter with a plant sprayer.

The system works well as advertised.
