Question Drill Porcelain Tiles

Can someone please help - I want to install new towel rails, shelves, etc on a floor to ceiling porcelain tiled wall. It is taking more than 1 hour to drill a hole. Has anyone found a way to drill these blasted tiles???

Claudia,
When drilling holes in porcelain, you need a rated bit, a variable speed drill, a sponge with water and some patience. Most "masonry" bits sold at the home improvement stores are bunk. You will want a bit rated for porcelain or granite which you can probably get from a real hardware store or from your local tile distributor. But even these "masonry" bits can be coaxed into getting the job done most times. You will want a slow RPM and constant perpendicular pressure. As you drill, you can hold the corner of a wet sponge to the bit as it's turning to keep the bit cool. If you've already run the bit at high speed, you may need to de-glaze it by drilling through a chunk of cinderblock or soft brick?
Let me know if any of this helps and I'll try to offer more advice if you need it,

Hey Claudia!

First of all.... is it a masonary bit? I had to ask

Is it a new bit? They wear out fast on porcelain.

As you drill, tilt the base of the drill off center in different directions slightly as you go. You will feel when the edges of the bit start cutting, center drill, repeat. <- hope that makes sense.

Water will help too, but you are on a vertical surface. towell, and a spray bottle?

Best of luck!

Try these bits. They are designed specifically for porcelain & will drill through a grade 5 porcelain tile in approx. 10-15 seconds, with no wander or cracking of the tile.

www.armegptc.com

they are stocked throughout the us.

For you local distributor call 561-351-9989 No longer in service.

or email: armegptc@earthlink.net

Dale, I need new PTC bits then, don't know about the 10-15 seconds.................not mine, they must be new and improved. They are pretty quick though. Don't forget the water, lots of water.

If you're drilling into a wall tile that's already been installed, do you need to get some kind of a squirter, or how important is the water, losts of water?

PTC has a pump sprayer, like a garden sprayer with an attachment that feeds water to the bit. I think the bits are great. Have heard a few guys complain but we get a lot of use out of the same bit, never really counted the amount of holes, but a good 100+. Then you will get a guy who does not keep the bit wet and it is gone in one hole. I started with 4 over a year ago and have 2 left.

Howdy Dale,

I tested your bits about a year ago and found them to be very worthwhile, especially if one needs a hole that is nearly chip free. I echo what Dave says about the water. I've never tried using the bits on the vertical.

Wow, John, that's a great hole. Obviously on a drill press? It looks like you're drilling over a bucket. Why not more support?

The quality of hole shown in the pic is achieved by using std. hand held drilling machines. Its also just as easy to drill on the vertical. Armeg will have a booth at the Coverings show in Orlando so if anybody wants to come along and see the drill demonstreated, or even for a chat. Please feel free. Booth 286.

We would also be very interested in any suggestions for additional sizes, or any suggestions for new tools, or improvements.

Approximately how much is a bit sufficient for 1/2 inch pipe?

The closest size to 1/2" we manufacture is 3/4" the list price for this is $89.99
this should last approx. 1000 holes in a grade 5 porcelain or granite.
