Review on Deburring Countersink Askwhy RD16 5 BC1651 Aluminum by Alvaro Delic

I only use this to clean up 3D prints, but for the money it's ok. I use a genuine Noga reamer in my garage for metal projects. They're similar, but I don't know how well they'll hold up against Noga in their intended use on metal. However, if you don't need a professional tool, this might work.
