Hi Graz,
In the past I have drilled a 20mm hole in a ceramic tile, using a flat ended diamond drill.
The trick was to use a piece of wood/metal with the correct size hole already drilled. With gaffer tape to position and flood the plate with water – haypresto??? :beer:
But go steady dont rush or :zap:

Starting off a diamond drill on a ceramic surface is never going to be fun. If you want to drill a 8mm diamond hole in it first make a guide by drilling an 8mm hole in a piece of thin plywood, then clamp/glue/hold that in position on the plate and start drilling through that hole.
Don't try to do it dry or the diamonds will clog with dust, generate a lot of heat, bind in the hole and likely cause the plate to ****ter. Proper diamond drill bits have a through-hole for water to pass through but for an 8mm hole you might get away with just running a hose on it.

Some good advice will get an old plate and give them a go, thanks again :bugeye: :thumbup:

Graz,

I've done a couple of these with my son. The "spade" type glass drills do quite a good job. you can start them in the right place by sticking some insulation tape to the back of the plate, using the drill bit in a cordless drill. Just like drilling tiles in the kitchen or bathroom.

Once the drill has just broken through, turn it over and complete the hole from the other side.

Good tip .... don't switch on the hammer action!!! :doh:

Another seriously good tip though is to use a couple of large pieces of Florists Oasis (that soft green sponge stuff) to support the plate while you're drilling.
