Cut through stucco wall
Worked surprisingly well. I used it to cut through stucco/concrete exterior wall. I wanted to install a round 4-1/8 receptacle for a security light and this cut the perfect size hole. Not deep enough to cut through completely, but got me most of the way there. I just used a 1/8 masonry drill bit to drill around and finally, a couple taps with a hammer to break through. Had this been about 1/4 deeper inside, it definitely would’ve cut through completely. Go slow and use a spray bottle to keep it wet. I cut two holes in a wall about 1-1/4 deep, still plenty of life left.

Helped me remove a headless screw
I used this to remove a screw on which the head had rusted and crumbled. It was used to mount a shower slide bar and we didn't have more replacement tile, so I needed to get the screw out. I measured the broken screw's mate's diameter and determined that these 6mm hole saws would work. Using the hole saw, I drilled through the cement backerboard around the screw. I went pretty slow as I wasn't able to use any water to cool or lubricate the saw. Probably took about 10-15 minutes. The screw came loose just as the hole saw broke, and lodged in the hole. After removing the problem screw, I just used a larger-diameter screw to bite into the inside of the broken hole saw and pulled it out. I was pretty hard on the saw, putting a good amount of force on the drill, and for the price I would consider this a consumable and a good tradeoff for getting the job done. I can't speak for other use cases but for mine, it worked very well and the price meant my DIY repair was a good value.

Very good, short term drill for tile or stone
I'm a remodeler, and purchased this hole saw to cut a hole in tile for a shower valve. Being so large, I wondered how I could get it to accurately cut a hole in my tile without it wandering and scuffing up the surface. I did three steps which made my hole cutout perfect. First I cut a hole in a piece of backerboard using the hole saw. This piece was to be my cutting guide. Then, I cut a piece of sponge and put it inside the bit so that it would release water and cool the bit as I drilled my hole in the tile. I positioned the backerboard on the tile and clamped it there. Then I soaked the hole saw and sponge in water and proceeded to cut the hole in the tile. The sponge and water kept the bit cool and the backerboard template kept the hole saw from wandering. It was a perfect cut! This bit is by far the most economic way to cut a clean hole. The bit is already much duller that when new, but it will work great for several cuts, but not many more than that. Keeping the bit wet and cook is essential- otherwise your bit might not last more than one or two holes. There are many others costing 10x more and made for daily use, but my use was one or two times only, and for that, this bit was perfect.

Got the job done...
I used this to install a 4" freestanding tub drain on a concrete slab floor. The bit worked as expected. It would have easily cut through the porcelain tile.

Good for TWO (2) holes...
I needed to cut TWO (2) holes in porcelain tile for tub faucet valves. This bit handled the job, but just. After the 2nd hole, the abrasive was essentially gone, and I would not want to use it again. Still, for my need, it was a better value than a much more expensive big name item which would have lasted but never been needed again. The cuts were smooth and clean. I used a scrap of Kerdi-board into which I had drilled a hole w this bit. Light pressure held the foam board in place on the tile, contained the water added into the cut-out void, and make the drilling start and finish easily. No skittering.

These bits are even tougher than I expected.
I bought these with the hopes that by buying a whole set they would be able to drill a small hole in a sintered (very hard metal) gear. I used one of these bits, drilled through the gear and into the shaft, and used an old broken drill bit to make a pin. The gear was slipping on the shaft and wouldn't turn the shaft to make my nibbler work. I tried a TiN coated bit and a cobalt bit to no avail. The sintered gear was just too hard. I used just one of these little diamond bits and it was still working when I finished drilling the hole through the gear and into the shaft. I couldn't see any wear on that bit. Simply amazing! The nibbler works fine (at least for now).

Will not drill holes in tile.
I ordered these because I had an expensive Bosch bit that drilled exactly one hole in the grout line of my bathroom tile wall. When I went to drill the second hole for a towel bar, the bit tip was trashed. So I bought these hoping to get maybe a dozen holes drilled into the tile for things like towel bars, hooks and the toilet paper holder. One of these finished the hole started by the Bosch bit, then was done. So between the Bosch bit and one of these, I got one towel bar installed. Two bits down. I grabbed a new one of these and didn't get through the glazed layer before the second bit was done. These are garbage and I am returning them in an effort to find something that will work. And yes, I was using a spray bottle and spraying water on them as they drilled. It didn't matter. The rough texture on the bit was gone in a few seconds. Also, the bit shafts are hollow so I didn't expect much.

This hole saw works well. I needed to cut a shower valve hole in a 12 x 12 tile and it did it nicely. I ended up cutting a guide block out of wood, then clamping it to the tile. I submerged the tile and guide block in a concrete mixing pan and filled it with water and had no trouble cutting the hole. It took about 5 minutes to cut at slow speed on a cordless drill. Recommended.

Etremely recomended. Cuts through tile like butter. Very easy to use, high speed at the start since it does not come with a pilot hole drill bit. Buy with confidence and guranteed.

Cuts a very clean hole with water. Made about 30 cuts in limestone so far and bit is going strong!
