I was hesitant to buy these based on reviews. However, these are made for ceramic, not for porcelain as many tried to use them on.
I drilled 18 holes to mount grab bars/soap dish with grab bar, and a towel grab bar and the bit probably would go another 30 holes with no problem. Just go slow, took about 20 seconds or less per hole. I use masking tape to mark out where I'm going to drill, plus the tape helps the bit from walking. I did not try to break the glaze on the tile before hand, with a nail punch. I just started drilling. Very impressed!

Rated 3.0 out of 5.0 by Cody Worked but...
I bought this set to drill holes for wall anchors to hang plumbing attachments (arms etc) in a new shower I remodeled. The tile was porcelain so not necessarily the hardest of surfaces. The number of holes I needed to drill was four (1/4) so I figured the price wasn't the bad ($15), I needed a new set of bits for this type of application and the product was perfect for the job as well as future ones due to the four sizes. However I burned through three bits with the four holes that needed to be 1/4.That is the 1/4 bit and the two descending sizes.
That being said, they DID do the job great with little to no chipping of the tile and no cracking at all. I suppose if they were a "one and done" set for a few bucks less it would make sense but for $15 and now I am down to one bit it does not work well for me.
I will recommend the set solely because they did drill a good hole in the porcelain.

Rated 5.0 out of 5.0 by Robe Excellent bits for tile
Have used both the 3/16 and 1/4 inch bits to drill anchor holes in bathroom tile for towel racks and other appurtenances. I'd guess I have drilled a minimum of 12 holes with each bit and I've noticed no indication that they are wearing. Just use a low drill speed, apply a bit of pressure at the start until the tip bites (you can hear the bit beginning to bite) and then proceed slowly. No water is necessary if you use a low speed. I usually put a couple pieces of masking tape on the tile to prevent walking. They work great. I haven't chipped or cracked a single tile.
To preserve wear on the tip I usually remove the bit as soon as it penetrates the tile and then switch to a masonry or wood bit as appropriate.

on average you will drill 4 holes in a regular tile before the carbide piece breaks and falls out

The reviews I read warned about bits getting dull quickly. I have bored dozens of holes with just one and it is still sharp. Makes nice smooth holes with little or no tear out.

I was looking for a bit (set) to drill a hole into a wine bottle.
I found this set, the price was great for the set. I started the hole with a small bit and then went to the larger size. I used a ( CORDLESS ) drill, submerged the bottle in water which kept the bits cool.

Rated 5.0 out of 5.0 by BDub64 Bosch glass and tile bit
Against the advice of the sales associate who advised me to get Ryobi's glass and tile bits, I chose Bosch. I felt from the look of the bits and the tips of them that they were superior to the house brand Ryobi. I like Ryobi for many of the DIY level power tools and have a number of the 18V rechargeable tools and batteries. However, sometimes you have to remember Ryobi is exclusive to The Home Depot and they will often push this line on you against other brands. I had purchased Ryobi masonry bits and they wore out and took a lot of effort to use in concrete block walls. Bosch and DeWalt are higher cost for a reason.
The bits from Bosch worked amazing!! I was drilling holes into glazed ceramic tiles on bathroom wall and kitchen wall. These bits did it in mere seconds with no hesitation. Follow the instructions and lightly score the tile, start the drill slow and easy and boom, it was done.
