I had to drill a hole through ceramic tiled it just installed on my wall. It did the job flawlessly I took my time and made sure that the bits stayed cool. Got the job done without any cracks in the tile or flaws. Just take your time and don't push and Rush the job when using the tool.

Used this to drill three holes in a large clay pot. It worked really well! Put pot rim-side down on a soft surface, outside. Wear earplugs and a mask. Wet the bottom of the pot. Start drilling at a 45 degree angle until the bit bites into pot, then move to vertical. Done!

I was nervous to cut through the porcelain tile backsplash in my kitchen to install a microwave bracket, since I'd never done anything like that, but this drill bit was able to drill two holes for the stud screws cleanly. I did have some challenges with the bit walking as I was starting a new hole, but I could have probably prevented that by applying more layers of tape to act as a guard. This isn't a fast process, btw. Expect to take a couple of minutes for each hole, using moderate pressure and speed, while stopping often to dip the drill bit in water.

This drill bit works better than other types of drill bits on porcelain. Most of the other 5* reviews are accurate. I used the bit to make 12 holes in porcelain tiles in a shower to install grab bars. It takes less than one minute to drill each hole. Be careful to start drilling at an angle to start the cut than slowly rotate your drill to a perpendicular position so that the bit doesn't slip across the face of the tile. Be diligent to clean the bit between each hole and check during each hole drilling session to clean out porcelain debris which will pack the channel inside the bit. The bit will get hot so spray with water or intermittently stop drilling and dunk the bit in water. The bit looked brand new after 12 holes. This bit definitely works well for the price.

This Lennox bit made short work of my project. I used it on porcelain tile and got clean holes every time. Keep it cool by way of dipping it in water periodically and keep the hollow shaft free of drillings and you'll have a bit that you'll be eager to use over and over. Very good quality. Well worth the price.

I am installing a railing along my front porch and had to drill approximately 36 holes through the porcelain tile. Because of the positioning, I had to drill a few holes with the improper technique, which burned them up in only a couple holes. When I used them the proper way, they lasted for at least 12-15 holes. The packaging has pictures to show the proper technique but it is not obvious. Here is the best way, which is consistent with the instructions. 1. drill a 9/32 hole through a piece of 1/2 -3/4 piece of wood. Make sure the piece is long enough to stand on or lean on while you are drilling. Drill the hole close enough to the edge so you can still use it as a guide when you drill close to a wall. 2. line the guide over the marked hole location. 3, drill just deep enough to create a circular ring in the tile. 4. remove the guide and begin to drill FULL SPEED and apply as much pressure as you can as you flood the cutter and hole with water using a squirt bottle. This will flow the debris out of the hole and keep the bit cool. The heat will not affect the diamond, but it will overheat the adhesive that is holding the diamond dust to the steel bit and cause it to release. 5. After each hole, use a finish nail to clear the tile plug from inside of the bit. If you don't do this regularly, the plug will eventually build up and jam into the inside of the bit. Then, instead of penetratingly into the tile, it will just spin in place and heat up. 6. repeat.

Great quality tool, as expected from a brand of Lennox’s reputation. Will definitely be ordering more in future.

Durable and long lasting. Relatively easy to use on ceramic but so slow on porcelain as expected. Keeping it wet and cool is a must.

I was forced to order this hole saw to complete a bathroom remodel in my home. I needed to open holes in the marble wall tile of my shower surround for the faucet stems and spout. Marble is not the hardest of materials, so I kept the drill speed down and sprayed the saw with water as it proceeded. No complaints, it quickly made a nice clean hole through 1/2 inch marble, thin set and backer board...I just wish I could have found one to borrow.
