Rated 4.0 out of 5.0 by Don Works well on cement shingle siding
I purchased these to drill holes in fiber-cement siding as my masonry bits had trouble drilling through. They worked very well- were fast and never walked. However; when I tried drilling porcelain tile the 1/4" bit broke after about one minute of drilling,

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.

Rated 5.0 out of 5.0 by George Nice bit set
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.
