Customer Reviews

Do the job, fast
I used these hole saws on vitreous china. The job was done neatly and quickly. I had started with a carbide grit hole saw, but, after hours of slow progress, decided to purchase these. The diamond dust hole saw took only minutes to complete the job. The carbide saw showed obvious signs of wear. The diamond dust saw looked as good as when I unpackaged it.

You might note the lack of a pilot bit and wonder how to center your hole. I used a small piece of plywood into which I had cut a hole to the size of the diamond dust hole saw I was going to use. I centered my template and secured it with duct tape. Once the hole was started, I was able to remove the template and continue.

Keep a spray bottle of water handy and frequently squirt the saw and material to keep it cool and lubricated.

Thumbs up
Great product at the price. I've only tried one of the bits so far but, it worked flawlessly.

Works well.
Great product. I used them to cut holes in 3/8" thick porcelain tiles. They take a while but they cut a nice clean hole without breaking the tile. Make sure to create a plumber's putty berm around the area you are cutting and fill it with water. This will make sure that the saw stays cool during cutting.
