Erbauer Tile & Glass Drill 7 x 77mm x 5.1mm Shank
like a knife through butter
these are great tile bits. after another from a hardware store broke thought Id by a hand full of these and one has outlasted the previous purchase go through the tiles with ease and don't even walk despite the fact the tiles are rippled well worth a go

Does what you ask
Bought tile bit to drill into glass (sparkle) effect tiles. Very good at starting off and cutting the hole. Does take some time.
Keep water at hand to spray on to bit, as it get very hot.
Drill on low speed and low torque (dont use hammer action)
I used the bit to drill in few mm and then used masonry bit to drill rest of tile and into wall.
Good overall, drilled 4 holes, so performance still okay. Just remember to cool bit down every so often.
