Help a begineer with advise on cutting holes in subway tiles

[Justintime]

Hello all,
I'm part way through a tiling job (floor and wall tiles) and I need to start thinking about how I'm going to cut circular holes through my floor tiles and wall subway tiles for the various pipes and wastes etc.

It present I've not fitted the tiles to the walls/floor that will need the holes.

I'm looking at getting some sort of cutter that can cut around a 45mm hole.
I've seen lots of diamond tipped ones on Ebay etc very cheap, but they don't have an arbour or pilot hole - how on earth can I cut the holes accurately with out onr?

Also, there will be plenty of holes where say the hole for the bath spout (wall hung) will mean cutting two tiles next to each other - how do I go about cutting those out - or will they be with a tile saw of some description?

Many thanks,

Justin.

Oh BTW I've got some hand held electric drills and a Makita SDS drill (mains) I can use

Hello Justin, the diamond tipped cutters are the ones you want, you can get them from the likes of eBay, pro tiler tools, ats diamond tools, and other places, the easiest way is to use it to drill a hole in a piece of wood or backerboard first then hold that firmly in place as a guide for drilling your tile. You need to keep them wet with a sponge or spray or whatever you find easiest, luckily metro tiles are very soft. Slow speed cordless drill is perfect, no hammer

You could try this
Erbauer Diamond Tile Drill Guide - http://www.NoLinksToThis/p/erbauer-diamond-tile-drill-guide/84524
And as @Localtiler says don't use the hammer action

thank you both for the replies.
will try my own guide holes first as I need to go bigger in size than the 35mm max of the erbauer guide.

Just cut a hole in a plastic adhesive lid or similar = Template.

or an off cut of tile and clamp it to the tile you want to cut as the template / guide
