> 24 hourOne star off because one of the bearings was off and loose in the box. Thought it was missing a screw, but found it. The diamond saws , is what I expect. Not any better than others I have purchased and not any worse. Use water and they will give you good life. The suction on the guide was weird. It stuck good on tile but did not stick at all to a non porous formica top. Wish there was some sort of case though.

> 24 hourThe bits are well made and withstood the task at hand which was about 1.5 of solid granite. The odd contraption they include with the bits is honestly a terrible attempt at whatever it is they thought they were solving. It is useless. I just chucked it away. I use a 90 degree portable press to prime my hole and then finish it off by hand with the drill. I wish theyd shave off the price and save us the extra plastic and bearings. Other than that, a great product.

> 24 hourThis kit worked well for the application. However, we had to buy a specific bit for our job as a 32mm was not included in the set. It seemed to have virtually everything else. I cannot speak to longevity as weve only used it once after we bought the size bit we needed. The suction cup did slip a little but didnt hurt anything.

> 24 hourI bought these to cut glass and ceramics. They work as described but won’t last very long. I got two good cuts and the diamond coating was almost completely gone. For big jobs I would purchase their higher quality cutting tools.

> 24 hourIn general work well. But first out of the box failed in 2 minutes. Would have given 5 star because it was inexpensive, had first not failed so fast

> 24 hourUpdate: The seller reached out to me after reading this review and offered a full refund or replacement. :) Original review: No instructions for the guide are included in the box. I stuck the guide to a clean, flat matte finish ceramic tile (not over a grout line), pressed the lever down, and there was enough suction to keep the guide on the wall, but not enough to keep it from wandering once I started drilling through the tile. I ended up making my own jig out of wood and clamping it in place to keep the bit from wandering. I drilled at medium speed using moderate pressure, pausing every ten seconds or so to mist the area with water. The 40mm bit worked fine, and got through the 7mm ceramic tile in a couple of minutes.

> 24 hourNeeded to drill thru our brick home and foundation stones to install a new furnace. Was initially impressed at how well the 2 bit went thru the brick, but then it caught and the drill spun, and bent the bit. I thought it was done, but I put the bit back in the hole and carefully bent it back straight (mostly) and was able to keep drilling. Make sure to hold the drill securely! Have to stop every inch depth and chisel out the brick plug as the bit bottoms out at that point. Next hole was through foundation stone (oolite I think) with the 1.5 bit. The cutting surface got gunked up with the dust from the stone and got stuck in the hole. Ended up having to use a bigger bit to drill around the stuck bit and with much patience and difficulty dig it out of the hole. The shank on this bit then broke off, leaving it useless. I was able to put a bolt thru the hole to get a little more use out of it (see the pic), but not ideal. Maybe a setup like a wood hole saw set - with one shank that screws on to all the hole saws would be a sturdier design. FYI If youre drilling a deep hole, the 3/8 collet forstner bit extender does work with these bits, but the shank on these bits is so short that only one set screw will engage the bit. And be careful that screw doesnt loosen so you lose the bit in the hole! If youre looking for a one time use, or just light hobby use, these bits might work, but any heavier use and they are just not up to the task. Hope this helps somebody.

> 24 hourI installed a new quartz countertop and needed to drill holes for the faucet and vessel sink. This kit made it easy to start the hole and maintain the cut. I only made one hole with two different size bits, so I cant attest to how well they hold up. But the suction apparatus worked great and made the job much easier. Great kit for a home owner.
