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）

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.

Excellent cut quality. No skating or drifting. No pilot holes. 5 holes in one 4 inch tile, with no breakage or cracking, on an unsupported tile. No chipping on all but the 1/2 inch bit, but it was minimal, and a bit of water, or higher speed than what I used, is very manageable. 4 pointed bit made drilling very easy with only a very fine powder left. Excellent product!

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.

Took 15 minutes to drill through the tile. Broke after 3 to 4 holes

I got these to drill into ceramic pots. I had never drilled through ceramic before and to be fair, I'm also a bit of a rookie on the drill. Packaging was nice and easy to open. I was easily able to put the drill bit in and drill through my ceramic planter pots without cracking them.Very happy with the price point and they worked well for exactly what I needed.

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.

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.

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!
