Perfect for my mistakes

I bought this tiny drill head because I had a piece I made with about 60 ish holes, and 13 were glazed closed. It worked exactly as I needed it to. The only issue I had was that it is a VERY small thin diameter and my Dremel chuck was a little bigger. I eventually squeezed it to hold. I can’t afford to buy a new Dremel so I just tightened it way too far….. but I saved my piece. Bottom line, I was very happy with he drill bit.
