6PCS Ceramic Tile Drill Bits, Mgtgbao Masonry Drill Bits Set for Glass, Brick, Tile, Concrete, Plastic and Wood Tungsten Carbide Tip for Wall Mirror and Ceramic Tile with Size (6mm-12mm).

Works on floor tile.

In an attempt to install a handicap bar in our shower I discovered just how hard real ceramic tiles are. I started with a standard 1/8" carbide tip bit. It would not even scratch the surface. Next I used a very small Dremel ball bit to make a starter hole. I was able to make a small indentation but in the process wore out the Dremel ball bit. I again tried the carbide bit but it was a waste of time. I accomplished nothing.I searched Amazon and found these bits. They were a bit spendy but the ratings were very good and most of the top ratings appeared to be by people who knew what they were doing. These bits are amazing. The box comes with two 2 ea. for the 6mm size. I started drilling using a water sprayer to clear the tailings every 30 sec. I also spun the bit in a water container every 30 sec. to cool it. I was shocked at how hard I had to push but after about 6 min of drilling, stopping, cooling and drilling I finished the first hole. I continued to drill and completed 3 holes without any damage to the ceramic tile. The only problem was the drill got so hot I had to let it cool for several hours. I was concerned that the bit might be getting dull but used the same bit for the next hole, and the next hole and finally the last hole. Two sets of three holes each and no damage or cracking to the tiles. If you observe the attached picture the top bit has never been used and the bottom bit drilled six holes through the hardest ceramic tile I have ever come across. It took no longer to drill the last hole than the first. I see no significant wear on the bottom bit other than the coating being worn off. Whiteout reservation I wholeheartedly recommend these bits.

Did the job. Wish they added 5/8” size.

These drill bits are awesome. Perfect clean cut thru kitchen backsplash ceramic tile. Didn't need to tape or use water when drilling. Took about 20 sec for 9mm tile each hole. Put up hood range last night without issues. I highly recommend these drill bits, especially for DIY projects.

Looked like a quality item. But didn't need them and returned them. Grab bars came with their own drill bit .

The best set i ever used

Did not do anything to tile. The edgesWere t even sharp! I would not buy again.

I bought these to drill holes in pots I bought at the thrift store to use for plants. It was pretty tough to make the holes, but because I have no experience doing this, I don't know if the time it took to make a hole was normal or if these aren't good bits. Regardless, it still ultimately made the holes and the price was right on the bits. I don't know if I would recommend these for heavy use, but if you just want to put a few drainage holes in flea market finds, I think these are a good bet.
