Lynn Posted February 26, 2013 Report Share Posted February 26, 2013 Hello, An aunt gave me these miniature bone. I try to make jewelry. I have to make a hole about 4-6 mm deep at the end of the figurine for my project. I tried it with a dremel. I used carbide bits without much success. Then diamond bits without much success ... I finally read that acid softened bone. So I put vinegar on the tip of my figure, and after 24 hours, I could drill a little but not enough (only about 2 mm). So I put sulfuric acid because it is more acidic than vinegar. After a few hours, I could drill more easily. However, I would like to know if there is a less dangerous method for what I need to do. I put a mask, gloves and goggles, but I do not like so much dust that occurs when I drill. I'm a little scared to breathe acid despite all my precautions ... Sorry if there are mistakes in my message. Is that I am French and I use google translation to help me. Thank you very much for your help Lyne Link to comment Share on other sites More sharing options...
