Using these bits for installing a wall against a concrete foundation. Still using the first bit after about 30 holes drilled. These work best with a hammer drill. Not an impact drill.

You can see in the picture that I had to drill through 1/4 glass mirrored tiles to create a hole to mount the brass flanges on my wetbar project. I bought 1/4 drill bits, similar to these but a different brand, that seemed to drill faster during my testing. However, I realized that 1/4" was too big. A lot of companies do not make glass bits like this smaller that 1/4"/6mm. I ordered 4mm. from this company - Mgtgbao. (what a stupid name).It definitely took longer to drill though a 1/4 glass tiles with the Mgtgbao 4mm drill but than it did with the other brands 6 mm drill bit. In the end, though, the Mgtgbao got the job done.I also tried the round diamond tip drill bits for glass. They were really SLOW. The Tungsten Carbide Tip bits seem to work better for my glass tile.This was my first project which required me to drill through glass, which is why I experimented with different drill bits.BTW - the super-expensive bits from the big-box hardware store ($17 for ONE bit) did NOT work any better than these bits - which cost less than $20 for 10 bits.

I needed to drill 6mm holes in a few large form porcelain tiles that I'm redoing our bathroom in to attach a few things through the tile to the subfloor. These bits were perfect for that. I watched a few online videos and most seemed to say that this style of bit is less likely to crack the tile as compared to the type of bits that look like metal bits and have the twisting grooves running the length of the bit. I can attest that 9 holes through the porcelain tile later and I have zero cracks to complain about. I ran the drill bits through the tile and kept a wet sponge handy and added water every few seconds to keep the tile and bit lubricated.I used 5 bits for the 9 holes as I didn't want to chance the tile cracking by using a bit too many times. I truly don't know how many drilled holes you can get out of one bit but I was keeping around two holes per bit. I included a picture of a test hole I drilled in a spare piece of tile and then a picture of the toilet flange that was installed on the tile as a result of being able to cleanly drill through the tile.I highly recommend these for any small holes you need to drill through tile.

You may or may not be able to drill all the way through the concrete with these. I used it on tile (with water for lubrication) worked just fine. Just go as far as you can with the drill. But take your time don't use too much force.These should be good for about 3 or 4 projects each.

I tried some other from Home Depot or Reno Depot, but they was expensive and not work really well.Here for this price, they really work well. Take note you could probably use one bit to make one-two or three hole. But at this price, it's worth it !

Comes with 10 bits six mm One holding CaseWould’ve been nice if there was various sizes in this kit , on tile make sure you use water when drilling it worked well on some of the tiles for the wall where I had to put holes inThey say if you’re drilling into concrete to drill dry I’m not sure I haven’t really done any experimenting with concrete yet but subject to later review updates

This is a good set but I wish they sold them in varying sizes rather than just a pack of a single size. I just purchased my first hammer drill and these work amazing with it. I remember trying to drill into the outside of my house and spending a half hour on one hole while these bits with my new hammer drill went through it in no time.
