This week only, the three-piece set is on sale.
It's unlikely, in my opinion. A cast iron sink is 98 % iron in thickness, with only a glass like material known as porcelin as the top layer being a glass like material known as porcelin. It's for that layer, not the cast iron, that you'll need a diamond hole saw.
The shank on mine was 1/4" hex.

Because they are inexpensive, I purchased several different sizes. They're great at what they do, and they got the job done quickly and professionally. All of this being said, I strongly advise you to purchase the Drilax hole saw guide, as these hole saws lack a centering bit and will walk all over your tile if you try to freehand the cut, causing the tile to be destroyed. The guide attaches to the tile with a large suction cup and holds the hole saw in place until you get it started. This was a two-person job because the saw blade needed to be cooled with water. I also used a cordless drill because I didn't think standing in a puddle of water with a drill plugged into 110 volts was a good idea.
" Unfortunately, it did not make it through, as shown in the photo. To accommodate various countertop thickness differences, I had to run to the big box store and buy a "standard" bit, which is obviously much deeper. This is a five-star piece if you have thinner countertops. I'm giving it two stars today because it was a waste of my time and money for a job that it couldn't complete.
I had to wrap duck tape around the shaft of the drill so it could grab onto something to cut the hole for my shower head arm in my tile, but it worked great. I'm not sure what it's supposed to be used for, but the shaft is completely smooth, so the drill won't be able to grip it.
Only one hole had to be drilled, and it easily passed through my 1 1/8" granite countertop. If more holes were needed, I'm sure it could do so. Note- While drilling, be sure to add water. I built a dam out of plumber's putty around the area where I was drilling and filled it with about 1/8" of water. It worked perfectly.
Those who complain are probably inexperienced and are using too little water and too much pressure. Allow time; I have mine mounted in a tripod drill press and apply a little pressure, but mostly let the machine's weight do the work. I've wrapped a clay ring around it and filled it with a few ounces of water. A spray bottle filled with water could also be used. It doesn't have to be soaked. Simply stay damp.
There was only about a 1/16th of a second left. Then it was no problem for me to finish the hole. The job was completed in under 5 minutes. I kept it wet the entire time, and my countertop was granite, so it worked out perfectly.
This is the first and last time I've used something similar to add a security bar to my shower. Although most, if not all, cutters should include a center bit, I was unable to locate one. Because I am not an expert, it would walk all over the tile, earning it only three stars.
I bought the Drilax 1" diamond drill (core) bit to install a soap dispenser in our 1" thick granite. The total cost, including shipping, was significantly less than any local store. br>The bit arrived quickly, and with the help of a 1" guide block, it made quick work of it, leaving a very smooth 1" diameter hole. br>Drilax is something I would strongly suggest.
