Drilling Porcelain Tile


I have to mount some fixtures (towel bars Ect.) to some porcelain wall tile and I was wondering what to drill it with. I have tried in the past with either carbide tipped bits or "tile" bits. They usally get so hot the carbite or tip falls out. Do they make a Diamond tip for porcelain?

Re: Drilling Porcelain Tile


Use an XCore bit in a rotozip for your pilot holes... Its pretty clean if ya got a steady hand

Re: Drilling Porcelain Tile


You need a diamond coated bit. Carbide won't do it

Re: Drilling Porcelain Tile


I have a set of diamond bits specifically for that task. Lennox actually makes a pretty decent set that you can pick up from Lowes for about 50 or 60 bucks. Four bits from 1/8 up to 3/8 I believe. Mine have held up very well. I use two drills when I am doing it. A small carbide in one drill just to get a pilot hole for the diamond bit. The diamond core bits tent to walk a bit on hard porcelain.

Re: Drilling Porcelain Tile


I'm not a tile guy by any means, but I use the diamond tipped bits at a slow speed. I use a 20oz bottle with a small hole in the cap for a lubrication applicator. It doesn't go quick, it's like drilling through metal. In a pinch I've used the arrowhead looking bits from lowes, they didn't seem too bad.

Re: Drilling Porcelain Tile


I am very sure the recommendations these gents have given you is what you need to lean to.

But.... if you are stuck with those crappy bits try spraying the bit while drilling with a spray bottle to keep it cool and it will get you thru the day.

Re: Drilling Porcelain Tile


Our friends at HD have a kit with they same generic diamond bit you find at any store, but it has a plastic container that keeps water on the bit. It comes with 10 double sided pieces of tape, one per hole, to hold the cup on. I ran out of tape before the bit was spent. Only like $15 for 1/4" & 5/16" too. I think the brand was Brutus or something like that.

Re: Drilling Porcelain Tile


It is Brutus and made in China

If you go to the tool section, they also carry Ridgid diamond coring bits. A little more expensive but they are better than the Chinese crap and are made in the UK.

Thought would revive the thread and add a bit I bought for some hard ass porcelain I needed to drill through for my shower glass install. Bought this bit after I burned up the $34 xbit for my rot zip. This thing worked great! Used a small spray bottle to keep it cool while I drilled!

Re: Drilling Porcelain Tile


I use CONCRETE DRILL BITS by bosh.

They last longer than any especially bit.

I tried the sds bits and they didn't touch this porcelain for some reason. I have had luck in the past with them.

The little core bit cut through real smooth.

Re: Drilling Porcelain Tile


$28 dollars, worth every penny. Drilled thru this porcelain like drilling thru soft wood.. Hilti bits are great

Re: Drilling Porcelain Tile


Running water to the cutting surface will reduced the chance of breaking tile, give you a smoother cut and extend the life of your coring bit.
