Rated 3.0 out of 5.0 by 1930sRemodel It's hard to drill thru tile, here take these.
Notice the tiny warning on the back of the package "Not for ceramic tile". They still worked if I went slowly and didn't "twist" the bit.

I needed to drill a hole in a glass jar for a small project. I selected a bit from the kit and it worked perfectly and did exactly what I needed to do with ease. I put a little "blue painter's tape" over the area I drilled prior to starting. No problems. Work safely and wear gloves!

Rated 1.0 out of 5.0 by MikeB One time use only... if lucky.
I tried to use these to drill a clay tile... what the manufacture recommends the product for clearly marked on the packaging.
I did a test run using a scrap piece of tile. To keep the area wet I drilled through the tile with a sponge around the bit. I turned down the speed of the drill, started out slowly, and with pressure on the sponge kept the area wet. Test run went perfectly.
The blade on the bit snapped as soon as I touched it to the next piece of tile; luckily I was able to get the hole drilled with the next size up. Next hole... the blade snapped as soon as I touched it to the tile... had to use the larger bit. Third hole... same result.
Next step.. off to Lowe's to get a Diamond Arbored Hole Saw. This product cost twice as much but was worth the money.

Rated 5.0 out of 5.0 by MicD Works on Spring Steel
I needed something with a very hard tip, as I had already burned up a couple regular drill bits, before I realized I was trying to drill into the extremely hard spring steel of a knife pocket clip I was modifying.
I was just trying to open up a small hole in the thin spring steel, and the tapered point on these bits was perfect.
Went slow and used cutting oil, got just the right sized hole I needed.

Easy to use but don't force it. This bit can get hot and break. That will break the bottle. Start with the smallest and work up to the size you want.

Rated 5.0 out of 5.0 by Eddie Ryobi Glass and Tile Bits #AR1650G Faster Than Bosch
Ryobi vs Bosch Glass & Tile Drill Bits, Ryobi Faster
I wanted to drill holes in some ceramic flower pots, and my multipurpose drill bits could not get the job done. On February 8, 2015, I bought a 1/2 inch Bosch Glass & Tile� drill bit and a 4-piece set of Ryobi Glass and Tile drill bits #AR1650G ranging from 1/8 inch to 5/16 inch. I started with the smaller Ryobi bits and they zipped right through the first ceramic pot. I used the Bosch drill bit to enlarge the holes, and it seemed to take much longer. I then tested each drill bit to see how long it took to get through another ceramic pot. The 2nd pot had a thick glazed bottom and took longer. The times to drill through the 2nd Ceramic Pot: Ryobi 1/8 inch bit: 40 seconds. Ryobi 3/16 inch bit: 50 seconds Ryobi 1/4 inch bit: 65 seconds Ryobi 5/16 inch bit: 70 seconds Bosch 1/2 inch bit: 170 seconds I then used a terracotta pot with 4 sides. Each of the Ryobi bits drilled through the pot in 5 seconds or less. The Bosch 1/2 inch bit took 35 seconds to drill through the pot. Both brands got the job done, but all the Ryobi bits did it in such a small fraction of the time it took Bosch, that I have to believe their better performance is related more to their design than to the larger size of that particular Bosch item. I know the drill bit brands would need to be the same sizes for an objective comparison, but I am going to try some other brands of 1/2 inch drill bits for glass and tile before I buy another Bosch. I would buy a Ryobi 1/2 inch drill bit for glass and tile if they made one.
