Doesn't "walk" on ceramic tile!
So far I love this bit for ceramic tile. Unlike the spade type tile bits, you don't need to tap the back of your drill to prevent walking. So far I've drilled around 70 holes and she's still good as new.
I've tried a couple holes on porcelain....not very impressed. A diamond bit would work much better.

First of all the bit is too short. They should have made at least 5 or six inches long. The bit did not last as advertised on the packaging. I drilled a few holes into ceramic tile and it was done. Waste of money for sure

Does not last long
Does not last long at all, good for 1-2 holes in ceramic. I got this so I could drill 5 holes to mount a glass shower panel. I made it through 2 holes started the third but was unable to finish.
At 14$ a bit that’s a 7$ a hole, sad performance to say the least.
I followed the directions and kept a low RPM and light pressure.
If this drill isn’t designed to drill holes into ceramic tiles. Don’t say that it is designed for that on the box.

It all depends on the material you are trying to drill into. There can be variances even within individual types of material.
I drilled twenty holes through 3/4" marble with one of these bits, and it could have kept going a little.

Packaging said "lasts 2x longer." I was able to drill 2.5 holes in tile with it. I needed 8.
Was able to use more traditional tile bits and finished the job. I found alternating the size of the bit a couple of times, part way through each hole, really helped.

This Drillbit dulls very fast when drilling through ceramic porcelain tile. I would not recommend it. I bought three and they all did not perform well at all. At $11.95 each these drills are not worth the price.

Good carbide bit for drilling tile and stone (not for porcelain). I use this in a cordless drill at medium speed with medium pressure, and use water to extend its life. The instructions do not say to use dry or wet, so I opted for wet. It easily drills through standard floor tiles. Patience is key, don't get in a hurry and it will work just file. Packaging has warnings that I managed to destroy while trying to open it, but they still don't specify whether to use wet or dry. Good bit for drill small holes in tile.

What can I say, It works exactly as described and for all the materials is says it does. I drilled a 3/16 hole in a 3/4" piece of granite in under one minute. I then used it for a couple of other projects around the house including ceramic and glass. Don't push hard, let the tip do all the cutting. Drip some water in the area of cutting while cutting and you will have a very clean cut. If you push too hard it will blow out the back or worse crack whatever your putting a hole in, It will also prematurely wear out the bit. If you follow those two simple tips you will have clean cuts and a bit that will last. I definitely recommend this.

I used this 3/16 carbide drill bit to cut through my granite sink countertop backsplash in order to secure it to the wall, plus some ceramic tiles and the bit cut through easily and effectively and held up very well with no signs of fatigue.
However, when trying it to bore through a hard `natural` stone , despite using minimal pressure, plus using water from a spray bottle, this bit quickly ran out of the strength it had and the carbide tip started to, for want of a better word, crumble. It was no longer effective to use on any other materials. Other than the failure to withstand drilling through some rock, it did however, work on tiles and my granite backsplash and perhaps I should have stopped with those but I wanted to try it out on its claimed potential. Disappointed with its ability to cut through stone and yet delighted at its performance with my other two materials.
