Hello, I bought the diamond grit cutting wheels for a single purpose, to cut a small imperfect geode in two for my daughter. When I got the cutting bits I found that they were mounted off center from the mandrel. This causes some excess vibration on the cutting tool so the overall quality isn't the best. With that said, the bits were able to cut through the many types of rock found in the specimen that I was cutting they cut well. I was cutting a rock that was about 1 1/2" inches (40 mm) in diameter and it only took me about 30 min. With the inexpensive price that I paid for them, I got a good bargain as I didn't even degrade the first bit that I used! Faithfully, Bowcoastie
