Porcelain Bathroom Tiles
11 Answers
I need some advice on drilling into porcelain tiles to fit a blind. Do I need a special drill bit or will using a new masonry bit be ok. I need the holes to be 6mm so was thinking of starting with 3mm holes and enlarging. Any advice appreciated.
Thanks

Use a slow speed and firm pressure until the drill starts to pierce the glaze surface then speed it up a little bit. I've always used 'spear point' masonry drills for this type of hole, they don't wander so much.
I'd stay with the 6mm size. If you start with 3mm and then go to 6mm you stand the risk of the 6mm jamming in the 3mm hole.
Obviously, do not use any percussion setting on the drill ☺☺☺

For a neat hole in such tiles, you should use a glass drill bit. These are good for drilling holes in mirrors, and so on. Their big advantage is that the edge of the hole does not chip, i.e. you get a neat-edged hole. You can use a masonry drill bit, but you might get a bit of chipping around the edge of the hole. If that will be covered by the fitting (wall cabinet, or whatever) the edge chipping does not matter. Your idea of starting with a small-diameter bit, then enlarging is a good one. Use brand new bits if possible.
I make a jig for drilling the holes. Use a piece of wood about 1/2" thick; drill a hole in it slightly larger than your diamond tipped bit; place this over where you want to drill, drill vertically to get the hole started; and once you have a good start remove the jig and carry on drilling keeping the bit and the hole well watered for cooling.
All good stuff from the other posters, Mass.
I just use a cordless drill with speed control. Gentler and easier to control than a mains drill, but that would be fine on a slow speed if you don't have a cordless.
I have no trouble using a 6mm bit only. A good tip might be to score a small hole with a pointy tile cutter first. That'll anchor the drill bit to avoid sliding.
