I had to drill 1/2" holes through ceramic tile in my bathroom to install a double shower curtain rod. I'd not used this type of bit before and was looking for a standard masonry bit. However I saw this and liked the point to keep it from wandering.
It worked flawlessly. I drilled 4 holes through tile, hardiboard, then drywall. Each were perfect. I drilled at slow speed with mild pressure. I wet the tip periodically with water. This is common sense to me. It keeps things cooled down and acts as a lubricant. This bit performed great.
Use as directed with common sense and you'll be very successful!

Rated 4.0 out of 5.0 by ABE Good bit, hard pots
Bil was easy to use and it fit the drill correctly. Hard ceramic takes time to drill.

I used this to install a Kohler Hydrorail. The last thing I wanted was for it to wander or chip/crack my bathroom tile. After talking to a HD rep, he recommended this bit.
You need to follow the directions and run it slow. It took me about 5 minutes to drill out four holes. The best part about the design is it literally does not wander. It started and stayed directly on my mark then made a clean/crisp hole.

Rated 1.0 out of 5.0 by Transplanted For Glass and Tile...Worthless!
I needed to drill 2 holes into each of 2 ceramic outdoor planters to assist in draining rain water. This bit is marked specifically for glass and tile...Well, there's an abundance of ceramic tiles out there, so I see no difference in a ceramic planter.
The only good thing I have to say about the bit when new, is the claim of no skip hole starting actually works...That's where the good ends.
Max drilling speed for this bit is rated below 2,000 rpm. As a result, I had my drill on the low setting around 870 rpm.
I found that I was unable to drill halfway through the first hole! When I looked at the bit, the sharp point was worn down, and the sides were worn inwards toward the shank.
This bit was now useless. I ended up drilling all 4 holes with a concrete bit. Although the concrete bit is not intended for this job, it did the trick, unlike this Bosch bit.
This bit has no strength to it whatsoever. I have absolutely no idea what you’d be able to actually drill with this bit.
Not recommended. Look for a different bit that will actually accomplish what it’s purposed for. This is not it!

Rated 5.0 out of 5.0 by Brewmaster Use a Drill Press!
I was hesitant to purchase this bit after reading the reviews, but bought one anyhow. I used it to drill holes in glass block for a project and it worked great. I used it in a drill press and worked slowly while keeping the surface wet to keep the bit cooled. I don't know how long it will last, but after a couple holes it is still going strong. I can imagine this would be nearly impossible to do with a hand drill, but on a drill press it works great.
