For my future reference, can anyone suggest a proven method of drilling
holes in unfixed and/or fixed floor tiles? The wall tiles are easy enough to
drill with a normal masonry bit although I did buy a "proper" tile drill
(more later...)

The problem was drilling the floor tiles. I tried several methods...

1) Bit of making tape over "proposed hole". Tap "X" with sharp screw to chip
surface. Drill gently with masonsy drill on slow speed.
Result: Chewed up masking tape and no hole.

2) Drill more vigorously with masonsy drill on slow speed.
Result: No hole but wearing through tile surface slowly.

3) Drill with increasing vigour on highest speed.
Result: No hole but wearing through tile surface less slowly.

4) Get out SDS drill and touch tile.
Result: Shattered tile.

Fix tiles down and plan to drill in place. 2 days later...

5) Go to Focus and but "proper" tile drill for £4.95
Result: Que for 15 minues only to be told they won't accept a credit card
for under £5. Faff about trying to find some cash in pockets as wallet at
home (only brought out to pay account at BM) Found cash, bought drill, vowed
never to return.

6) Mark up new tile. Start drilling hole, slow then high speed with proper
tile drill.
Result: Tile drill "lightly marks" surface and glows red as which point I
stopped.

Repeat steps 2 and 3 for around 30 minutes.

7) Grab angle grinder and try and think of how to drill a hole with a 9"
diamond blade?
Result: Tea

8) Drill on slow speed with "proper" tiles drill using cold tea as a
lubricant.
Result: Drill bill snatches and shatters but does drill into the tile by
about 3mm.

9) Spend another 30 mins drilling remainder of hole with a newer masonry
bit on slow speed.
Result: Approximate hole.

10) Repeat above (minus tile drill) for another 4 holes!!!!
Result: Go home, drink alcohol and post to NG.

Once did that. Considered buyin diamond drill but v. expensive (£30+ as
I remember) Decided to make square cut out with tile saw and fill in
round/square gap with grout.

Buy tile drill set from Toolstation, they don't shatter like the
Screwfix one's do. However, they do lose their edge if they are allowed
to overheat, but can be sharpened with a quick touch up on a diamond
wheel. If you need a larger dia hole, then resharpening a normal masonry
drill to a shape similar to the tile drills with the diamond wheel can
be worth while.

I'm planning on drilling a hole this weekend in newly laid tiles. When you
say floor tiles, do you mean the thick red earthenware style tile or do you
mean the floor tiles that look almost identical to wall tiles?

Hmmm, I suspect I've been lucky. As much as I hate to admit buying
them, I found the "Bullet" bits to be damn good for this job.
I just used a standard drill, set to a low speed and ensure that the
hammer setting is off.
I start very slowly until the drill has 'bit' and then I increase the
speed slightly and apply quite a hard pressure.
If at any time I think the drill bit is getting too hot then I just
back off (go for a cuppa) and then start again.

The life of the "Bullet" bits when used this way isn't great, but
they're not that expensive....
