How does this drill insert into my hand held drill? It looks so different than my other drill bits.

I want a diamond drill bit to drill drainage holes in pottery for my plants. I saw a video using a diamond drill bit. I want a diamond drill bit, but am unsure if it can be inserted just like my other drill bits?

Answer: 
It fits in like any other drill bit. The large side is what fits into the drill chuck. The small side is a hole saw.

Rated 4.1 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by 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! December 31, 2011
Rated 4.0 out of 5.0 by Required to drill a hole in porcelain 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. December 16, 2013
Rated 5.0 out of 5.0 by 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. January 2, 2014
Rated 2.0 out of 5.0 by 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. January 18, 2014
Rated 5.0 out of 5.0 by 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. February 2, 2013
Rated 4.0 out of 5.0 by 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. January 28, 2014
Rated 5.0 out of 5.0 by A must Use for Porcelain Tile This worked great for Porcelain Tile. Tried other drilll bit here from the site to make multiple holes on Porcelain Tiles but theses were the only ones that worked May 27, 2013
Rated 3.0 out of 5.0 by Good for one or two holes Good for one or two holes in porcelain tile, probably works much better on the softer ceramic tile July 2, 2013
