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）

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.

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 price on these bits, but that wouldn't matter if they were junk, but they're not! Great quality; I just finished installing a grab bar in our ceramic tile shower and used the next-to-smallest bit. It quickly cut through the tile, and didn't wander. All six holes went smoothly.

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

I needed a new set of masonry drill bits because my old set became scattered (someone around here doesn't put things back where they belong, so I'm hiding these)! I like that there are some duplicates of the more commonly used sizes. I've already used these more than a dozen times and am happy. They seem to be good quality. If something happens, like if one breaks or becomes dull after little use, I'll be back to detract stars. Meanwhile, I do recommend these for the price value and quality.

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.

Yes, it will drill concrete. However, the 1/8 inch drill tip broke off after the third use. The larger size seems a more sturdy.

Nice! These worked perfectly with my drill and allowed me to drill holes into my ceramic pots so they can be used for more than decoration! 😊 Drilling was a VERY slow process for my thicker pots, but I got through it without cracking them, so I call that a win! Highly recommend.
