So I have a chalice that I want.to frag. I just got a 545 diamond wheel bit for my dremel. I have seen videos of people fraging with a dremel. my question is, where to cut. The chalice is growing off of the rock as if it is plating. Is it ok to cit where it is hanging off the rock. I will be cutting just the skeleton and flesh if I do. It is kind of thin. Here is pic. Any word of advice or experience would help.
