A very useful tool. I recommend it to everyone. It is robust and easy to work with.

This is an awesome invention. If you need to cut nice perfect round holes in tile, especially porcelain, this is the Diamond Drill Bit Tile Glass Hole Saw to use. It worked beyond what I expected.

This is the perfect tool for drilling into acid-resistant countertops. I had to enlarge a faucet hole and it worked great. It was my first time ever drilling into this type of countertop and it worked perfectly. One will not go wrong with this tool in the tool box. I highly recommend this one you will not go wrong!

Read how others used this and you'll be glad you bought this. I used plumbers putty to keep in water and diamond tip hole saw and went slow on marble and I cut a 3-inch hole that the greatest tile cutter in the world would envy.

This really helped us drill perfectly round holes, and in the exact location, we needed them to be, in our hard porcelain tile. I figured this gadget couldn't work as easy as advertised but I knew drilling the holes freehand was going to be a frustrating mess so we gave this a try. Bought a diamond hole saw and were good to go. It was quick and easy to use and we couldn't be happier with the outcome.

This part worked great, I used some duct tape under it to make sure it didn’t get squirmy when I first started, held in place great for my cut through granite to install a soap pipe.

Great Diamond Drill Bit Tile Glass Hole Saw! It worked perfectly, allowed me to drill a hole in different tiles porcelain, and ceramic without an issue. Gave me a perfect hole! It is very easy to use, just don't forget the water.

I used to make these, to cut holes in the stone. But I'm retired. I thought what the heck? Buy one instead. This Diamond Drill Bit Tile Glass Hole Saw is worth every penny and saved me the time it takes to put one together myself. The suction cup and bearings are of good quality and work very well. Why take a risk and the extra time & effort, cutting free hand? I always appreciate smart tools that make precision work, fool-proof for the professional.

I ordered and used this to enlarge a countertop hole for a kitchen faucet. I had been worried about centering the hole given the existing hole being in place. The suction on this guide kept it in place and it worked perfectly. As a result, I avoided having to pay a $150 countertop service call. Well worth the price.

My husband used this for the shower remodel and he raved about how well it worked. He then used it to drill the holes for the vanity sinks and faucets.
