I was skeptical, as this is a 40 dollar set of diamond bits for the price of one name brand bit at Lowe's. I have made about 6 cuts in 1.5" granite with the 2" bit with no signs of it slowing down. For the cost, that will do just nicely. Keep them wet when cutting and I expect you will get some decent mileage out of them.
The last time I drilled a hole in 2" of granite it took 15 minutes. With these bits it took less than 2 minutes to go through. The hole was clean and the granite did not stick in the bit. I used it for a sink top that the contractors messed up on during our renovation, and now have a terrific looking sink for my outdoor kitchen.
Wanted to drill a hole in granite for a vessel sink. These worked well, although the granite was a little deeper that the saw depth. Was able to take part out and then finish. After I finish building the vanity, I'll use a different size for the faucet. Very pleased.
I bought another rather inexpensive set recently, and the "diamonds" washed off immediately drilling the first hole through soft sandstone. These are much sturdier. I drilled a total of about 10" through sandstone using the first bit (1.75") and the bit held up very well. Obviously these aren't what a full-time granite driller should buy, but for the homeowner who has occasional reasons to cut holes in stone, these are perfect.
Took some practice to cut holes in wine bottles for lights, but once I had it down I was popping these things out right and left! Only drawback is that the glass can get stuck IN the bit... and I can't remember if there's a back poke hole to pop the stuck ones out...
Using the guide with the wet hole saw bits, makes life easier and helpful for all tile bathroom fixtures.
I used it for tile and it cut right through no problem, and I like how they fit my Milwaukee drill!
Fairly good product. My first try using the guide was not successful as the drill bit walked on me. As a result, i duct taped the guide to the tile as shown. I did this for each drilled hole location and all holes were drilled successfully. I did have have a few edge chips when drilling on porcelain tile. I would buy it again.
This hole saw set is more than $100 cheaper than spyder, lennox, bosch, or similar. I use these for plumbing and electrical holes through porcelain and ceramic tiles, and the holes produced are exactly as I would expect from even the best brands. I am extremely happy with my purchase. I also use the guide,worth it as well. I have extremely high expectations and all where exceeded for the price paid. I highly recommend this kit.
The product cut great! Everything worked out well was just left with one less bit in the set.
This drill bit is amazing! With a little water and about a minute and a half this bit cut right through an inch and a half of very strong fire kilned clay. Washed the boy off and sun dried it. Looks like it has barley been touched. I would have been happy to pay twice as much for the great set of diamond hole saw bits.
Very nice set for the money. Plenty of sizes to choose from and the carrying case is very nice. I used one of the smaller drill bits to drill a hole in an old Mason jar to make a lamp. The Mason jar happened to be the liner of the inside of an older water cooler bottle. I was happy with the ease and speed that the drill cut the glass.
The bits went through very well but have not used them twice.
My quartz is 1” thick and bit measured as cutting 1 1/8” but it bottomed out before I broke through. So I tapped the hole with a small ball peak hammer and it broke out. It will take an odd shape out of the bottom of your counter top so beware if it’s exposed. In my case nobody will see it.
All in all for the price of one bit at Home Depot I got a set of 10. I’m happy!
