Review on 🔧 Portable Tapered Drilling Chamfering Sinking Tool by Maurice Stavros

This is a specialty tool that I will not use often. I had to enlarge the bridge bolt holes on the guitar. I bought it because it was cheap and I could use it as intended. The metal is not finely worked so if you need it for production I would look elsewhere. A nice feature is that you can load this tool into a drill chuck, but I only used it by hand because I was fine tuning an existing hole.
