Had to use that's when drilling through my quartz slab and they worked beautifully. Make sure you use water when drilling!

Great thus far. I have used the 50mm and have bored three holes into glass already. It is still going strong.

It’s a cheap Chinese probably tool, the shafts that fit into the drill are basically all different, not that that really matters but is weird, I used multiple and one specific one to drill through about 7 bottles and it still works good. For the price of this whole set you can get maybe 1 brand name drill. For what I need it for once in a while it’s great

Was happily surprised when I saw the quality of this set. Because of the low cost I did not expect the amount of diamonds on the cutting edge. I use these for cutting glass for stained glass projects. They arrived quickly and work very well. I would buy these again. Without a doubt.

I've used a smaller and a larger one so far. Both have made several nice, clean, holes, without any reduction in performance. Take it slow, and cool the bit with water regularly, and they work very well.

Drilled a 1-3/8" hole quickly and easily. Squirted with a spray bottle - cut through ceramic tile like a boss. Does want to run away when you start - start at an angle until you get a groove established, then you'll be good to go!

These little drill bits work. Had to make the hole in my birdhouse smaller so the big birds wouldn't be able to stick their beaks in and terrorize the little birds. Worked great.

Very valuable for the money. I bought them for my tile project of my bathroom

Go slow, use lots of water, not the highest quality...but the price is INCREDIBLE! I can still get 8 to 10 cuts per bit before they wear out. If you do it dry and get it hot you will burn them up in 1 hole.

I bought these to use to drill holes in bottles. So far I've drilled about 8 holes and have not had a problem. A good investment for a small price.
