I bought these to put holes in some nice ceramic pots because my schlumbergera (Christmas cactus) and spider plants were getting BIG and I needed big pots with drainage, I had some big ceramic pots with no holes in them, and these drill bits were cheaper than buying new big pots. I had never used a diamond bit before.I don't know if diamond drill bits are supposed to stay on course, or if the wobbling was due to the fact that I didn't know how to properly use them. The holes might have a little shelf here and there. But these bits put holes in the bottoms of my ceramic pots just fine using my Craftsman electric drill. The pots did not break. And I am very happy with them. I did wear my kid's chemistry class goggles, and am glad that I did so.
