Cutting a circle in a granite tile

[penguiness]

I would like to cut a circle from a spare granite floor tile to make a counter saver. It is 12mm thick. I have been quoted a £ 100!!!!! Can anyone suggest where i mught get it done? I live in hampshire. Many thanks

a diamond hole cutter 125mm on 365drills website

Is it absolutely necessary to have it circular?

That diamond cutter will not hack granite at 12mm!
My wet diamond wheel would do it, but would not be perfect.
Walk into a monumental mason's place with it .. they may do it "on the side" for 20 quid.

You could also possibly try a local Glass Supplier as they do a lot of cutting and grinding with thick plate glass.
Just a thought!!
