Review on Amana Tool Countersink Adjustable No Thrust Cutting Tools by Sam Sergio

Significant wobble on entry after only a few uses. The material of the main adapter connected to the drill chuck is not very strong. I think I've used it about a dozen times and was surprised it was already bent. I was very careful with this, but turned the bit over with the bit turned on (I'm sure we've all done this). I can't believe this could warp the drill shaft.
