Like some comments below, read the instructions. The bit has to be wet at all times, removing occasionally to clear debris and ensure that the bit is wet and doesn’t overheat. I have drilled more than 20 holes in ceramic tile and there is still life left. Keep 2 sided sticky pads on hand, once they get wet they are useless.

We had to drill two 5/16″ holes in our 1/2″ tile granite backsplash to install a new microwave. This little gadget saved the day. The water well is small so had to refill it a couple of times in order to drill each hole but not a problem. It’s small size makes it easier to use in tight spots. No special drill needed. We used our cordless drill. We placed a towel under our work area to catch the excess water from the refills so that we wouldn’t need to remove the unit each time the top half was refilled. What great little invention!

Has a problem staying on the wall were your drilling the hole to catch the water. Used several pieces of tape to complete the drilling. Also the holes for the water to go through the bottom part went to fast and filled the bottom part to fast. Not worth the price, you can put the bit in a dish of cold water every few minutes.

Goes through glass quickly and cleanly. I thought the bit would destroy the tile when drilling near the edge of a 1″ x 2″ glass tile, but it worked like a champ. I had a lot of holes to drill, so I thought I would run out of the stickers, but you can also drill free-hand and periodically dip the bit in a cup of water. I drilled 12 holes and saw no wear on the bit. The water-drip system worked well, though I had to tape up some of the holes or it would run out of water too quickly. Also, the sticker seals the water from dripping down the wall only if there are no grout lines under the seal. If you’re going to use those spring activated toggle bolts, you will probably need a bigger bit. All in all, a great buy.

This is a good set up but you will have to buy three of them to drill out 6 holes I was drilling through 1/4 porcelain. It cuts really clean wish you could just buy more bits than buying kit

The drill did what it was supposed to, but should be considered a throw away item since the bit only holds up to a few holes before breaking down. Even with the water on the bit, the tip will melt and flatten. It’s a bit messy, but for the price was probably to be expected. The first hole or two was impressive, but after that went down hill. I was disappointed that installing my shower doors that I was forced to go through two bits just to drill six holes. That starts adding cost to the overall project.

Excelent performance. Worked very well to do two holes in wall tiles.

This works for 2-3 holes in hard porcelain or ceramic tile. It is a good idea but cheaply made and the bit is of low-average
