I enjoy making jewelry and am working with pearls. The holes were too small to get the chain thru and the drill I had purchased, well, the bits were too big. I have had extreme satisfaction with this small drill. One has to be careful in using the bits b/c they are a little fragile, giving their small size. Excellent purchase and I have purchased two! Has really simplified my work and decreased my stress!!!

I have these in my hands and I still can't believe that exist drill bits so tiny. I have hair in my head more thicker than these bits. the only thing that confuse me a little was the identification. I am a modelist, I have bits of 1/16 and 1/32, but the thicker of these looks like 1/64 or more thin. the box is great, with a system to get only the desired bit. great product at great price.
