Yes, I bought one of these (well, it's a pair) to drill the procelain
floor tiles. They are superb compared to ordinary (~£5) tile bits.

having recently tiled the bathroom I'm now looking to drill a few hole in
the tiles.

the problem being that the tiles are approx. 9mm think and are
limestone/porcelain.

It has taken about 30 mins to get one 6mm diameter hole done this morning
with a combination of a 6mm diamond tile cutter bit and a 6mm carbide tipped
SDS.

While the tile bit does slowly grind away at the tile this is a long and
laborious process, the bit used is new and a low drill speed was used.
keeping the area wet is a little difficult given that its half way up the
wall.

the current tile bits I've got were the cheap option, two for about the same
price as one Bosch tile bit. I wil probably at least try out th eothe
roption in my local B&Q but is there any merit in going for the tile bits
available at screwfix

Thanks for the opinion.

Given the trouble I've had with the cheapo bits I can see the order going in
tomorrow, first off I might check out a few local merchants to see if I can
get hold of any quality gear locally... but then again the wife's been
waiting 4 weeks to get the sink back in so what's another couple of days.

last time I had to drill porcelain tiles I think I just used my SDS.
What are limestone/porcelain though?

the tiles have a limestone appearance but I believe they are essentially
porcelain

My SDS hradly even scratches the surface when using a new carbide tipped bit

Well are you trying to drill limestone, or porcelain, or ? I
guess you do mean porcelain, because of the time it takes!

I normally use ordinary cheap masonry bits - just sharpen your TCT
bit, put more of an angle on it than appropriate for masonry so
it looks like a tile drill (it then *is* one). To keep it wet, use
a bit of hose! What drilling machine are you using? Are you using
hammer action or not? N.B. bits blunt quickly in very hard stuff
and you will need to "touch them up" (ooh-err missus!) often.

My porcelain sink just laughed at my new Bosch SDS bit. I ended up
using (drill) mounted grinding stones to go through it.

Still took about 1/2 hour though (with stops to let bit & sink cool
down) to get through :-(

Why a special drill? Just mark the centre, carefully scratch the glaze to
score/break it with a tungston-carbide tipped scriber, put masking tape over
it to stop the drill wandering, and drill fairly slowly with an ordinary
masonary drill (rotary, no hammer.) Piece of cake.

If you need a large hole, make drill a small one first, then craze the glaze
(sic!) around the hole and enlarge it and so on.

Not on teh wall tles I had to drill last week.

Full hammer and it took ten minutes per hole and ruined two masonry bits.

I've tried using regular masonry bits on vanilla wall tiles. Yes, the
masonry drill will do the business. But nowhere near as easily as a
proper tiling bit.

I refrained from using hammer. But by the end was tempted to use
roto-stop and a big chisel :-)

On regular wall tiles drilling them is a doddle, but the ones that I've got
up are 9-10mm thick porcelain.

I'm looking at about 20mins for a 6mm diameter hole using a combination of
6mm and 8mm tile drills and a 6mm tct drill. I persevered with using
standard Bosch and B&D tile bits but as I've still got 9 holes to drill to
mount the shower rail, screen and other bits it's time to bite the bullet
ant try out the screwfix offering that Grunff gave his blessing to.

At least the sink is now secured to the wall, and I'll have a wee break at
the weekend before tackling the rest of the holes.

Get a grinding wheel (pref. with water feed or trough), sharpen
some ordinary TCT masonry bits so that they look like tile drills.
Drill the hole and change bits regularly! Sharpen bits, next hole...

I went to fit some new taps in a bathroom a few days ago. Sink was
secured to the wall, two screws holding it firm at the lower edge at
the back (where they invariably are).

I discovered that the sink wasn't actually sitting on the pedestal,
but was floating a couple of mm above. Which suggests to me that this
sink was being held in place by the sealant - the screws wouldn't hold
it there I'm sure.

Perhaps I'm just over cautious about these things but I thought the
general idea of the pedestal was to take some of the weight of the
sink. I wouldn't feel comfortable fitting a sink like this where the
sink is pulling on the sealant with virtually all its weight, and the
sealant is pulling on the ceramic tiles. The ceramic tiles are pulling
on the adhesive, and the adhesive .....

Lots of problems are caused by blunt tools (ooh-err!), even down
to using a carving knife that's been used to cut meat on a china
plate or whatever.It is really, really worth sharpening TCT bits
every so often (or minute, in your case, perhaps!).
