Like Tyfigher said, concrete/masonry bits will work but they need to be used in a hammer drill on the 'hammer drill setting'. The size/brand/quality/condition of the bit and drill makes a difference too. They are however pretty rough/violent and wouldn't be my first choice.
There are bits for drilling through tile as well as diamond coring bits which have already been mentioned.
