Complete novice (and simpleton) needs to drill into two kitchen wall tiles
to put up a magnetic knife rack. The tiles are ancient, and if i crack them
or drill out of level tiles could not be replaced with matching ones.

It's also right near the sink where 'she who must be obeyed' will see it all
day. If i mess up, i'm dead or worse.

I've seen a workman drill into kitchen tiles and initially his drill goes
'all over the place' until it 'bites'. He's probably had a lot of
experience at this, i'm guessing that for me it would bite in the wrong
place.

Grateful for any tips on the 'safest' way for me to drill the tiles.
Thanks.

score a tiddly cross with a diamond tipped tool, and use a diamond
tipped drill at low pressure and SLOW speed.


Or if you use one of the mini diamond *core* drills, put masking tape
over the tile, mark that, and then start very carefully lining up on
e.g. a biro drawn cross.
