3 otters 15Piece Diamond Hole Saw Kit, (6mm-50mm / 1/4"-2") Glass & Tile Drill Bits, Ideal for Glass, Bottles, Pots, Marble, Granite Stone

Well worth the price, as long as you follow the instructions and keep the bit cool with water so it doesn’t get hot they perform very decent. Also in mind the price of this set and it does well for your money. If this tool is something you foresee yourself using every day then you will probably want to invest in a more professional much higher priced set. If this is something you’re only going to be using a few times then this is the set for you. They cost under a buck a piece and you can’t beat that price. If this set is going to see a lot of use then it’s probably not going to stand the test. They are somewhat cheaply made but once again for the price they do a decent job for the price. I would probably buy again for my purposes.

It surprised me. It's making perfect circles and do the job as it has to be

This product is great. After a few uses it doesn't work the best. Eventually they will dull out and have to be replaced.

Clearly these aren't meant to be the highest quality tile hole saws judging by the price. I was not expecting a lot from them, as I only needed to cut a few holes. I was very much surprised! These did a great job on my tiles. I noticed a little chipping on the 7th hole I cut (in picture), but it will be covered by the escutcheon. The bits show some loss of diamond coating after use, but they are still usable (29mm bit was used, 25mm is new in picture). I'd never used a hole saw on tile before, and I found that if I clamped a piece of wood or tile with the the proper size hole in it over the top of my tile, I didn't have a problem with the saw walking away as others have noted.

I bought these a while back (maybe a few months) and just now got around to using them. I needed a 1 3/8" hole drilled through some ceramic tile for some copper pipe to stub through my floor for hydronic baseboard heating. Anyway, the closest one I found in this kit (if you wanna even call it that) was 40mm. Would've preferred standard, not metric, but whatever. You get what you pay for, right? Guess that's on me. I'm sure others have already pointed out the downsides to these, but here's my quick take. They're okay, if you go easy on them and put your drill on low speed and for god's sake stay in line with what you're cutting. Being that the arbor is made into the saw, it will bend if you get out of alignment with your work. This is what happened to me, halfway through a cut. Luckily, I was able to throw this thing in a bench vice and straighten it back out to finish my cut. The cut came out fine, but I have a few more to make, and honestly, I don't think this think this thing will make all of them. So...is what it is. You get what you pay for. I will go to the hardware store tomorrow and buy a quality diamond hole saw kit. This one is probably okay if you gotta make one or very few cuts, but otherwise I don't like it all that much. 3/5. Wouldn't recommend or buy again, honestly.

Drill bits used for ceramic glass acrylic and China. Worked well lasted quite a long time would recommend.

Not good when working with granitw rock. Even when applying lot of water to cool the process the rod attached to the tool head will snap. Lost three of them already. May work fune of soft material like glass or a thin marble surface.

Don’t expect to have these in the toolbox for year . But for $9. U get a lot of different sizes and they work for a few holes . Can’t ask for anything more than that . Drilled 2 holes with one size and 2 holes with another and cut like butter through both . I’m sure I could get a few more cuts but my job is done.

Good enough, for the money. There's some reviews saying that they're only good for one hole - Well I've used one for two holes (I mucked up the first one, my fault) in ceramic tiles, and I reckon it would go again. Recommend making a jig/guide with a bit of timber with a hole in it the same size as the hole saw, to help guide it in. These are DIY grade tools, which is fine for the price - I bought the whole set for much less than one of the saws would have cost from Bunnings, and I do only need them to work a couple of times; I'm only renovating one bathroom. Realise that you do get what you pay for, but if you only need to make a few holes, then these are the go!
