how do you cut circles

as @Crispy says.
diamond tipped hole cutter but going slow and plenty of water as a coolant.
if you have drilled a tile with a normal drill they tend to burn if to fast.......

 

Have you run out of corners then?

 

In a Belfast Sink

 

Depends on the sink suppose but normally if its for taps they go behind the sink. tricky plumbing job as well. i fit the taps and 2m of flex on the work top before fitting.
Does thats make sense

 

It would.

 

Dont forget to centre punch it before you drill! Dont want you slipping off centre eh!

 

Best to give it a good whack to get through the glaze

 

Yes , I have cut holes in ceramic sinks (in france some come without holes),just thought I would try the cutter on my plastic ...

 

That because the french stick the taps on the wall.

 

Why is this thread titled incorrectly?

 

are you sure?

so I had to drill for the tap...

btw did the pipe with my rusty hole cutter ,it was a bit too big...

 

You have a cutter for rusty holes..?

 

Let me rephrase that, traditionally taps were fixed to the wall but with the modern world of standardisation more and more are being fixed to the sink itself.

 

Those modern sinks usually have a knock out bit for the tap. One each side so that you can have the draining board left hand or right hand.

 

Stupid French

 

Isn't trepanning what they did in medieval times to drain folks heads of bad humours? Bad humour as in the ancient four humours theory, nothing to do with Mrs Brown's Boys. C'mon @bernjb56 , you're a scientist, am I on the right lines here? Did you offer trepanning at your place?

 

We did - every Tuesday morning. Messy business.
