Get a piece of 6mm timber/mdf and drill your hole in this first.I might consider that kit if these get blunt quick... The last 20mm I did earlier in the SDS, went a lot quicker for stopping and dunking in water..Defo the way forward
Then place the board over your tile where you require the hole, hold or stand on the board and fill it with some water with a squeeze from a wet sponge. The board will stop the drill skating and the bit cool
Good luck.
