It worked very well. One should be careful not to let the drill bit overheat, especially the smaller one, otherwise it bends and eventually it breaks.

Dear Customer, thank you for taking the time to post your rating on Rubi products. For future reference, it would be helpful to provide comments regarding any issues you may have had with our product so that we can address your legitimate concerns. At Rubi Tools, we take our continuous improvement program very seriously and we always appreciate constructive feedback that will help better our product.
Feedback such as what material were you drilling through, did you use water with these wet drill bits, what speeds where you using to drill, or did these not fit your drill would be very helpful to determine what went wrong. For example, one dry cut with wet bits will destroy the diamond surface of the bits and permanently damage there ability to drill holes. We are here to help and want to ensure that we do what we can to help you through your project.
As always, feel free to contact customers service at 305-715-9892 or by email at rubitools.usa@rubi.com so that we can help resolve any issues and answer any questions that you may have regarding your purchase. You can also find our tips on our Rubi YouTube video channel for extra guidance.

Excellent kit! A must-have tool if you were do drill a porcelain tile. I used this kit for drilling 6 holes for a toilet flange in a porcelain tile floor on a concrete slab in the basement. It worked as expected. You just have to go slow and easy on the drill bit. Also make sure you have plenty water to cool of the bit as it gets hot.

Good idea for keeping glass or ceramic cuts wet
Good idea for keeping glass or ceramic cuts wet. The hole cutting (drilling) bits are of decent enough quality for do quite a few jobs. The smart aspect of this kit was the ability to keep the cutting tool, and glass, cool and wet. The advantage of this is cutting down on hazardous dust created from hard ceramics and glass debris, not just keeping the substrate from fracturing. This is a great little kit, because you don't have to configure your own, water source solution, to drill safely. Although it's not the most optimal solution, it is a solution. It also comes packaged together. I'd recommend it.
