10-Piece Masonry Drill Bit Set for Concrete Tile Glass Ceramic Brick,1/8 to 1/2 Inch Drilling Bits with Triangle Handle,Tungsten Steel Alloy Tip.（Black）

If I could give this product 10 stars I would.I used it to drill a hole through a tiled wall. I was most worried about the bit drifting from the center of the hole once it started rotating. It did not and held to the position I wanted. I drilled 6 holes without issue - sharp on the last hole as the first.One tidbit I'd share is to drill wet. Water takes away the waste (ie. powder created from the drilling process) and the heat. Keeping the drill bit cool is an important element of keeping the tool sharp. We did this using a spray bottle and keep a steady stream of water on the work area.

Great drill bits!! They drilled through ceramic & hard plastic plant pots, with ease! My project went smoother than I expected. They seem to be high quality...& for a great price. I definitely recommend these drill bits!

Some tile is HARD to drill through. I needed to install shower safety bars and neither my regular drill bits nor my carbide masonry bits could make a hole.I decided to try this set and I'm glad I did!I used the smallest bit first to drill the (12) pilot holes. I drilled at a very low speed, dipping the tip of the drill bit in a glass of water every 30 seconds to cool it off. It was a slow process. I was concerned that the bit would wear out and tried a couple of times to switch to a carbide masonry bit to finish the holes, but those just wouldn't penetrate the tile. My concern was unfounded. The smallest bit from this set made it through all 12 holes, slow and steady.Then I enlarged the holes with each next size up until they were big enough. That went much more quickly. It seems that the initial holes are very tough, but enlarging holes is easier. Even my carbide masonry bits worked for that.These bits are a great value, and work wonderfully if you take your time and make sure they don't overheat (by dipping in water). High end diamond bits would have probably saved time, but cost at least 10x as much.

I simply bought these because they were inexpensive and I needed a spare set of masonry bits. These seem ok but pretty sure they'll hold up longer than my other ones did

worked great to drill thru shower ceramic tile and concrete substrate. clean hole no tile chipping at all drilled several holes to install shower grab bars. will definitely buy again when needed

Quality is not what I expected, maybe you get what you paid for. I used two of them and the tips got gnawed off in only one use.Buy a better quality ones.

This set of masonry bits worked very well with my ordinary home electric drill (corded). I followed the directions, kept the bits wet by dipping in a bucket of water, and they drilled through the brick veneer on the front of my house with no difficulty. I was replacing a flagpole bracket that had pulled out with new, larger expansion shields and bolts. I thought drilling a 1/2" hole would be hard, but these bits worked easily and cleanly. I didn't need a heavy masonry drill after all.

Excellent drill bits. I ordered these and diamond drill bits to make holes in marble and zellige tile, which are both very fragile and easy to crack. These carbide bits are much easier to use, so I hoped they would work, and they did an excellent job with not a single cracked tile. Make sure to drill a pilot hole with a small one first.
