How do I drill a SQUARE hole into tile to install an electrical socket

[Deleted member 1779]

With tiles getting bigger and bigger (some large format porcelain tiles are now 800mm x 800mm) then how do you ensure
a perfect fit for a plug socket, electrical socket or other item.

Some installers grind out from the back of the tile. We hope to show you a neat little trick.


This 90 second video explains it:



The basics are

1) Mark out the tile

2) Mark out the corners

3) Drill out the corners

4) Grind out the straight lines.

By drilling out the corners you are GUARANTEED a perfect result every time. With some tiles costing £50+ its expensive and time consuming to make mistakes.

Angle Grinders can overcut quite easily especially with discs in the 230mm range. A 115mm disc gives less curve so more accuracy. But it only takes a moment to over run.

Yes we know its a cheap soft ceramic! But its just to show the steps

skip the drilling section and move straight on to grinder.........imo.........same result at least 15mins quicker...and that is in any material....

oh and you saved a few bob........

what do you lot think?.........or is it me doing it wrong?......or missing a "TRICK?"

It is true there are other ways to do it. And using a grinder to do the entire job is one method.

But there does come times when its really important to get the detail right.

Let me give you an example of a hatchet job done in a multi million pound development.....

So above is a Bathroom I have been working on via a Construction Site.

OK so an angle grinder is used to make chop saw cuts (see below)

OK So the above IS FINE because thats not going to be seen

ITS NORMAL for a bathroom install. And no probs with it

This is fine too.

The shower valve is an awkward shape. ANd has been chopped out.

This is not a problem

And now the installer tries the same trick on a light fitting.


AND CHOPS IT OUT.

This is a MULTI MILLION pound development. And the installer thought it was fine to tile this. AND GROUT IT.

And the installer thinks the work will be signed off...

My suggestion (if my pics are a little crude) is that there is a surefire way to achieve the result. A little more elegant.

Hope it makes sense.

TOTALLY AGREE WITH OTHER METHODS OF DOING THE SAME THING !!!!

Re: How do I drill a SQUARE hole into tile to install an electrical so

okay........fair point......BUT YOU HAVE TO ADMIT..........ITS TO DO WITH THE INSTALLER!!!!........ and nothing to do with drilling!!!!!...or drill bits...........

I would have that cut out in a heartbeat.....and all the others.......not a drill, rotozip, dremel or anything else in sight.......in fact 90% of the jobs I go to
(BLIND...as in never been there!).......ts60+ and an angle grinder!!

oh......I can cut a perfectly neat hex the size of a 20p piece with an angle grinder........easy!

six cuts from the rear of the tile and a pin hammer!

If that's the standard of work in a £multi-million development how would they leave a bathroom in a 3-bed semi?

Shocking !!!!

I just plunge cut on my saw.

Grinder for me too especially on porcelain , easy to handle and does the job in minutes.

Of course holes in middle of tiles can be avoided by good setting out generally too.

I honestly can't see what the advantage of using a hole cutter is in this situ tbh.

No slight on your product by the way .

I'm a big fan of the porcadrill hole cutters, but I honestly wouldn't use them for this either. I plunge cut them on my cutter too, and rarely need to have a 2nd go at it.
I've seen some shocking tiling in multi million pound properties, but that takes the biscuit!! How does someone with so little pride in their work get jobs!?!
