Review on Enhance Your Jewelry Making Process with Chuck Collets for Small Pieces by Deron Gilliam

Have you ever seen a 62 mil drill run over 100 mils? I had. The collets seemed decent and the main body seemed fine. The collar that grips the collet seems to have a crazy offset between the threads and the conical surface that grips the collet. There was also a lot of sanding dust in the box and the parts were covered in some kind of rusty goo.
