drilling a tiled wall

[johnscales]

Hi all.

I tiled an on suite recently and am about to re fit the accessories for the room (towel rail, mirrors etc).
I bought the following item from screwfix to drill the holes but as its not pointed it slides around (tested on a spare tile).

Do I deed to do something to get the hole going first? If so what? Or
have I bought the wrong type of drill bit. Incidentally i'm using a cordless drill if that matters. I've used it to drill concrete before so I doubt power will be an issue.

Thanks.

Stick masking tape over where you want to drill to avoid the tip skidding before it bites; DO NOT use hammer action.

I need to put in a very light basic shower set. Will a 18v Bosch driller/driver be enough to drill the holes mainly through grout with plaster board behind.
Surely I don't need a hammer driller for such a lightweight job.

i am assuming that they are just a ceramic wall tile, if so your cordless will do sufficiently.
personally on ceramic tiles i use these

Thanks all.
I sed my dremel grinding bit in the end to start the hole (pierce the surface), then the the bit I bought from screwfix gripped and went through easily.

PLEASE DONT HIJACK SOMEONE ELSES THREAD. It breaks forum rules & can be very confusing for regular contributors; if you read & understood my post to the OP, it should have answered your question

Hello,
Your cordless drill will work fine on any tiles. I always apply painters tape to the tiles first before drill and go slowly letting the drill bit do the work.
I use http://www.screwfix.com/p/bosch-exp...racking url&gclid=CNurnKCciLwCFVMdtAodyjwALw# and have never had any problems with tiles cracking.
I hope this helps. Have a great day.
