Rated 5.0 out of 5.0 by CTGuy Wow!
My son & I spent 1.5 hours drilling two holes in porcelain tile using 5 carbide bits. I was going to buy more bits, but decided to try this one instead. What a difference! We drilled the final two holes in 10 minutes - 9x faster. (It wasn't the quality of the carbide bits. My contractor drilled through this tile and it took him about this long as well.)
The instructions are on the bit. To drill vertically, you'll need two people - one to operate the drill and one to hold a paper towel under the bit and spray water on it. All you need is a spray bottle to keep it cool.
Talk about the right tool for the job!

The secret to using this drill bit is to have a helper spray a continuous stream of water on the bit and into the hole while you are drilling. The first bit I bought was only good for 2 holes even though I would stop every few seconds and sponge the bit with water. When I bought the second bit, I asked my wife to spray continually while I drilled and that made the difference. I was able to drill 4 holes in about 8 minutes. The bit is still good for a few more holes.

Rated 5.0 out of 5.0 by BilltheEngineer Works great on very hard stone
I used this to drill four holes to mount a shelf in my bathroom in some stone tile. Not sure what kind of stone tile it is, but standard masonry bits would barely make a mark in the stone. After making four holes in 20 minutes the bit still looked like new. I kept the bit cool with ice cubes while drilling and it worked like a charm. Holes were nice and straight and clean.

Rated 2.0 out of 5.0 by joeydubs Only Good For a Few Holes
I used this bit on 6 holes in porcelain tile and it failed on the 6th hole. For the money, I would expect it to work on small projects for many years, not fail after the 6th use. The only reason I gave it a fair rating was because it did work well for the 6 holes it drilled as I had no issues of cracking/splitting any tile.

Rated 4.0 out of 5.0 by RIck Pretty good tool
This drill lasted 10 holes in porcelain tile following the manufacture's instructions. It was slow going but held up well and could probably go a few more holes before replacement is needed.

Rated 5.0 out of 5.0 by DJCutcher Perfect for drilling holes in Porcelain Tile
I was having extreme difficulty putting a grab bar in my shower. Several hours and (4) carbide drill bits later I found this product at Home Depot.
With the Ridgid diamond drill bit, I was able to complete the project, where at one point it seemed hopeless...
I completed (5) holes, and the drill was still working like new.
Great product for drilling holes in porcelain tiles.

Rated 3.0 out of 5.0 by catchey Good for one or two holes
Good for one or two holes in porcelain tile, probably works much better on the softer ceramic tile
