You need no hammer, and a bit which will either cut or abbrade the stone. I'd go with a diamond bit and slowly abrade the hole, with water cooling. A drill with a clutch will be necessary for a larger hole.
Be sure you have a replacement tile available before you start. If the material won't play ball you may need to cut the tile in two through the spot, and gnaw the hole away with jaws.

Marble is soft so a typical Bosch masonry bit will do the trick. We have gone over to using those diamond bits or hold saws and they work very well especially in granite, quartz, or porcelain tiles. For larger holes, we only use diamond hole, saws. Counter installers chuck that holesaw into their small angle grinders without a pilot bit but they use a wood guide and a bit of water. That method drills a very clean 1 3/8 hole.
