Review on Garage Rotary Holder Mandrel with Enhanced Polishing Capabilities by Richard Cuneo

This would be a great product as the slots are big for bits/cutter and the center compartment is great for files etc but it doesn't twist/spin easily which is a lot is frustrating. I tried it on multiple surfaces to see if that was the problem, but no, it's just bad design. I have several lathe drill bit holders and they soon bounce back so I don't think it's user error. I don't recommend this if you want a holder that rotates easily.
