Opening up the hole on a tile.

Hello Guys,

I need to open up the the whole on already fitted tile for a waste pipe.

I think the best course of action would be a small grinding wheel that would go on the end of the drill, kind of like what you would see on a Dremmal.

I've searched toolstation & screwfix without any luck for the bit only. Does anyone know anywhere else, 'Chain' that might do them?

When you say waste..is it 110mm(sewage).. or 40mm(sink)...?

Also what type and size off tile is fixed to the wall..?

What is the wall made off..from the outside to the inside..render/pebbledash/.facing brick/cavity(with cavity infill)..conctete block/aereated block ect /timber framed....?

You don't want to go core cutting holes without knowing what the substrates are made off first...

Lets say inner wall is concrete block,then a diamond core cutter will get ruined,you would be better stitch drilling...
More info required mate..
