3/4 in hole good, 1 in hole better. That gets you a full 1 and a half inches from nails and dry wall screws etc and allows electricians to come back and pull more wire etc. Depending on circumstance you may also want to put steel plates over the 2x4 where you drilled the hole, so if some idiot comes behind you with trim nails longer than 2 inches you wont get a short or set the house on fire also a good idea where plumbers drill for pipes...

You use a diamond core tile drill which is the appropriate size to the diameter you need. Common drill sizes for tiles are 6mm and 8mm for rawl plugs. For service pipes they are 16mm 30mm and 40mm. These will cover radiator pipes, waste pipes, shower head and other hole sizes. To stop the diamond core hole saw or drill bit from slipping you need a guide plate to hold it steady on the tile.
