Average review
I ordered these after burning up several other manufacturers product. I am so glad that I found the ad for these bits. We are a small jewelry business and as such we cycle through several operations on a monthly basis. We will work on the tumbled products from our bank of tumblers every four weeks in process and then we mount these stones into jewelry. One way we mount the stones is to drill a hole through them and fit a small piece of metal through the hole and attach that to an earring or necklace. We make several other pieces of jewelry but mostly earring and necklace sets. We have always lost several valuable stones to the drilling process until we began using these drill bits which are engineered to drill stone. I have usually lost about $25 worth of broken stones each time we drill. No more stone broken.
